{{Judicial interpretation}}

'''Statutory interpretation''' is the process by which courts interpret and apply [[legislation]]. Some amount of interpretation is often necessary when a case involves a [[statute]]. Sometimes the words of a statute have a plain and a straightforward meaning, but in many cases, there is some [[ambiguity]] in the words of the statute that must be resolved by the judge. To find the meanings of statutes, judges use various tools and methods of statutory interpretation, including traditional canons of statutory interpretation, legislative history, and purpose.
In [[common law]] jurisdictions, the [[judiciary]] may apply rules of statutory interpretation both to legislation enacted by the [[legislature]] and to [[delegated legislation]] such as administrative agency [[regulation]]s.

== History ==
Statutory interpretation first became significant in common law systems, of which historically [[English law#Common law|England]] is the exemplar. In Roman and civil law, a statute (or code) guides the magistrate, but there is no judicial precedent. In England, Parliament historically failed to enact a comprehensive code of legislation, which is why it was left to the courts to develop the common law; and having decided a case and given [[ratio decidendi|reasons for the decision]], the decision would become binding on later courts.

Accordingly, a particular interpretation of a statute would also become binding, and it became necessary to introduce a consistent framework for statutory interpretation. In the construction (interpretation) of statutes, the principal aim of the court must be to carry out the "intention of Parliament", and the English courts developed three main rules (plus some minor ones) to assist them in the task. These were: the [[mischief rule]], the [[literal rule]], and the [[Golden rule (law)|golden rule]].

Statutes may be presumed to incorporate certain components, as Parliament is "presumed" to have intended their inclusion.<ref>Trevor Lyons (2016), ''Notes on the English Legal System'', Liverpool John Mores University</ref> For example:

* Offences defined in criminal statutes are presumed to require ''[[mens rea]]'' (a guilty intention by the accused): ''[[Sweet v Parsley]]''.<ref>Sweet v Parsley [1970] [[Appeal Cases Law Reports|AC]] 132, [1969] 2 [[Weekly Law Reports|WLR]] 470, 53 Cr App R 221, [1969] 1 All ER 347, HL, reversing [1968] 2 QB 418</ref>
* A statute is presumed to make no changes in the common law.
* A statute is presumed not to remove an individual's liberty, vested rights, or property.<ref>As with [[EU law]], so in the UK an individual who is specifically targeted by a statute will normally have standing to bring a challenge by way of [[judicial review]].</ref>
* A statute is presumed not to apply to the Crown.
* A statute is presumed not to empower a person to commit a criminal offence.
* A statute is presumed not to apply retrospectively (whereas the common law is "declaratory": ''[[Conspiracy (criminal)#Conspiracy to corrupt public morals and conspiracy to outrage public decency|Shaw v DPP]]'').<ref>''Shaw v DPP'' [1962] [[Appeal Cases Law Reports|AC]] 220</ref>
* A statute is to be interpreted so as to uphold international treaties to which the UK is a party. In the case of EU law, any statutory provision which contravenes the principle embodied in the EU treaties that EU law is supreme is effectively void: ''[[R (Factortame Ltd) v Secretary of State for Transport|Factortame]]''.<ref>''R (Factortame Ltd) v Secretary of State for Transport (No 2)'' [1991] 1 [[Appeal Cases Law Reports|AC]] 603</ref>
* It is presumed that a statute will be interpreted ''[[ejusdem generis]]'' ("of the same kind"), so that words are to be construed in sympathy with their immediate context.

Where legislation and [[case law]] are in conflict, there is a presumption that legislation takes precedence insofar as there is any inconsistency. In the [[United Kingdom]] this principle is known as [[parliamentary sovereignty]]; but while Parliament has exclusive competence to legislate, the courts (mindful of their historic role of having developed the entire system of common law) retain sole competence to ''interpret'' statutes.

==General principles==
The age old process of application of the enacted law has led to the formulation of certain rules of interpretation. According to Cross, "Interpretation is the process by which the courts determine the meaning of a statutory provision for the purpose of applying it to the situation before them",<ref>Rupert Cross, Statutory interpretation, 3rd Edition, p.34 {{ISBN|978-0406049711}}</ref> while Salmond calls it "the process by which the courts seek to ascertain the meaning of the legislature through the medium of authoritative forms in which it is expressed".<ref>SALMOND: "Jurisprudence"11th Edition, p.152</ref> Interpretation of a particular statute depends upon the degree of creativity applied by the judges or the court in the reading of it, employed to achieve some stated end. It is often mentioned that common law statutes can be interpreted by using the Golden Rule, the Mischief Rule or the Literal Rule. However, according to [[Francis Bennion]], author of texts on statutory interpretation,<ref>Stanford Libraries, [https://searchworks.stanford.edu/view/10398508 Bennion on statutory interpretation: a code], accessed 25 November 2022</ref> there are no such simple devices to elucidate complex statutes, "[i]nstead there are a thousand and one interpretative ''criteria''".<ref>{{cite book |last1=Bennion |first1=F |title=Understanding Common Law Legislation: Drafting and Interpretation |date=2009-05-28 |publisher=Oxford University Press |isbn=9780199564101 |page=12}}</ref>

=== Intention of the legislature ===
A statute is an edict of a legislature,<ref>Supreme Court of India, [https://indiankanoon.org/doc/932434/ Vishnu Pratap Sugar Works (Private) Ltd. v. Chief Inspector of Stamps], U.P., AIR 1968 SC 102, p. 104</ref> and the conventional way of interpreting a statute is to seek the "intention" of its maker of framer. It is the judicature's duty to act upon the true intention of the legislature or the mens or sentential legis. The courts have to objectively determine the interpretation with guidance furnished by the accepted principles.<ref>R v. Secretary of State for the Environment expert Spath Holme, (2001) 1 All ER 195, p. 216(HL)</ref> If a statutory provision is open to more than one interpretation the court has to choose that interpretation which represents the true intention of the legislature.<ref name="auto">{{cite journal |last1=Nourse |first1=Victoria F. |title=A Decision Theory of Statutory Interpretation: Legislative History by the Rules |journal=Yale Law Journal |date=2012|volume=122|issue=1|url=https://www.yalelawjournal.org/pdf/1104_6t1o52ma.pdf}}</ref><ref>Venkataswami Naidu v.

=== Conflict of laws within a federation ===
{{More citations needed section|date=March 2016}}
[[Federal republic|Federal]] jurisdictions may presume that either federal or local government authority prevails in the absence of a defined rule.  In [[Canada]], there are areas of law where provincial governments and the federal government have concurrent jurisdiction. In these cases the federal law is held to be paramount. However, in areas where the Canadian constitution is silent, the federal government does not necessarily have superior jurisdiction. Rather, an area of law that is not expressly mentioned in Canada's Constitution will have to be interpreted to fall under either the federal residual jurisdiction found in the preamble of s. 91—known as the Peace, Order and Good Government clause—or the provinces residual jurisdiction of "Property and Civil Rights" under s. 92(13A) of the 1867 Constitution Act.  This contrasts with other federal jurisdictions, notably the [[United States]] and [[Australia]], where it is presumed that if legislation is not enacted pursuant to a specific provision of the federal [[Constitution]], the states will have authority over the relevant matter in their respective jurisdictions, unless the state's definitions of their statutes conflicts with federally established or recognized rights

==== Meaning ====
{{more citations needed section|date=March 2016}}
The [[judiciary]] interprets how legislation should apply in a particular case as no legislation unambiguously and specifically addresses all matters. Legislation may contain uncertainties for a variety of reasons:
* Words are imperfect symbols to communicate intent. They are ambiguous and change in meaning over time. The word "let" used to mean 'prevent' or 'hinder'<ref>{{Cite OED | let | id=1}}</ref> and now means 'allow'. The word "peculiar" is used to mean ''both'' specific ''and'' unusual, e.g. "kangaroos are peculiar to Australia", and "it's very peculiar to see a kangaroo outside Australia".<ref>{{Cite OED | peculiar}}</ref>
* Unforeseen situations are inevitable, and new technologies and cultures make application of existing laws difficult. (e.g. does the use of a new cloning technique create an embryo within the meaning of statute enacted when embryos could only be created by fertilisation?)<ref>{{Cite journal|last1=Pattinson|first1=Shaun D.|last2=Kind|first2=Vanessa|date=2017|title=Using a moot to develop students' understanding of human cloning and statutory interpretation|journal=Medical Law International|volume=17|issue=3|pages=111–133|language=en|doi=10.1177/0968533217726350|pmid=28943724|pmc=5598875}}</ref>
* Uncertainties may be added to the statute in the course of enactment, such as the need for compromise or catering to special [[interest group]]s.

Therefore, the court must try to determine how a statute should be enforced. This requires '''statutory construction'''. It is a tenet of statutory construction that the legislature is supreme (assuming constitutionality) when creating law and that the court is merely an interpreter of the law. Nevertheless, in practice, by performing the construction the court can make sweeping changes in the operation of the law.

Moreover, courts must also often view a case's '''statutory context'''. While cases occasionally focus on a few key words or phrases, judges may occasionally turn to viewing a case in its whole in order to gain deeper understanding. The totality of the language of a particular case allows the Justices presiding to better consider their rulings when it comes to these key words and phrases.<ref>{{Cite journal|last=Brannon|first=Valerie|date=11 Feb 2021|title=Statutory Interpretation: Theories, Tools, Trends|url=|journal=Congressional Research Service|publication-date=5 April 2018|volume=|pages=25|via=}}</ref>

Statutory interpretation is the process by which a court looks at a statute and determines what it means. A statute, which is a bill or law passed by the legislature, imposes obligations and rules on the people. Although legislature makes the Statute, it may be open to interpretation and have ambiguities. Statutory interpretation is the process of resolving those ambiguities and deciding how a particular bill or law will apply in a particular case.

Assume, for example, that a statute mandates that all motor vehicles travelling on a public roadway must be registered with the Department of Motor Vehicles (DMV). If the statute does not define the term "motor vehicles", then that term will have to be interpreted if questions arise in a court of law. A person driving a motorcycle might be pulled over and the police may try to fine him if his motorcycle is not registered with the DMV. If that individual argued to the court that a motorcycle is not a "motor vehicle", then the court would have to interpret the statute to determine what the legislature meant by "motor vehicle" and whether or not the motorcycle fell within that definition and was covered by the statute.

There are numerous rules of statutory interpretation. The first and most important rule is the rule dealing with the statute's plain language. This rule essentially states that the statute means what it says. If, for example, the statute says "motor vehicles", then the court is most likely to construe that the legislation is referring to the broad range of motorised vehicles normally required to travel along roadways and not "aeroplanes" or "bicycles" even though aeroplanes are vehicles propelled by a motor and bicycles may be used on a roadway.

In Australia and in the United States, the courts have consistently stated that the text of the statute is used first, and it is read as it is written, using the ordinary meaning of the words of the statute.

Below are various quotes on this topic from US courts:
*[[U.S. Supreme Court]]: "We begin with the familiar canon of statutory construction that the starting point for interpreting a statute is the language of the statute itself. Absent a clearly expressed legislative intention to the contrary, that language must ordinarily be regarded as conclusive." ''Consumer Product Safety Commission et al. v. GTE Sylvania, Inc. et al.'', 447 U.S. 102 (1980).  "[I]n interpreting a statute a court should always turn to one cardinal canon before all others.&nbsp;... [C]ourts must presume that a legislature says in a statute what it means and means in a statute what it says there." ''Connecticut National Bank v. Germain'', [[Case citation|112 S. Ct. 1146, 1149]] (1992). Indeed, "when the words of a statute are unambiguous, then, this first canon is also the last: 'judicial inquiry is complete.{{'"}} 503 U.S. 249, 254. 
*[[9th Circuit Court of Appeals]]: In the dissent from ''en banc'' rehearing of ''[[Silveira v. Lockyer]]'' 312 F.3rd 1052 (2002), dissent at 328 F.3d 567 (2003) at 575, Judge Kleinfeld stated "it is 'a cardinal principle of statutory construction that we must give effect, if possible, to every clause and word of a statute.' ''[[Williams v. Taylor (Terry Williams)|Williams v. Taylor]]'', 529 U.S. 362, 404, 120 S.Ct. 1495, 146 L.Ed.2d 389 (2000)."
*[[Supreme Court of Virginia]]: "Every part of an act is presumed to be of some effect and is not to be treated as meaningless unless absolutely necessary." ''Red Ash Coal Corp. v. Absher'', [[Case citation|153 Va. 332, 335]], 149 S.E. 541, 542 (1929). This is known as the rule against surplusage.
*[[Supreme Court of Alaska]]: "In assessing statutory language, unless words have acquired a peculiar meaning,  by virtue of statutory definition or judicial construction,  they are to be construed in accordance with their common usage." ''Muller v. BP Exploration (Alaska) Inc.'', 923 P.2d 783, 787-88 (Alaska 1996); 
*[[Arkansas Supreme Court]]: "When reviewing issues of statutory interpretation, we keep in mind that the first rule in considering the meaning and effect of a statute is to construe it just as it reads, giving the words their ordinary and usually accepted meaning in common language. When the language of a statute is plain and unambiguous, there is no need to resort to rules of statutory construction. A statute is ambiguous only where it is open to two or more constructions, or where it is of such obscure or doubtful meaning that reasonable minds might disagree or be uncertain as to its meaning. When a statute is clear, however, it is given its plain meaning, and this court will not search for legislative intent; rather, that intent must be gathered from the plain meaning of the language used. This court is very hesitant to interpret a legislative act in a manner contrary to its express language, unless it is clear that a drafting error or omission has circumvented legislative intent." ''Farrell v. Farrell'', 365 Ark. 465, 231 S.W.3d 619. (2006)
*[[New Mexico Supreme Court]]: "The principal command of statutory construction is that the court should determine and effectuate the intent of the legislature using the plain language of the statute as the primary indicator of legislative intent." ''State v. Ogden'', 118 N.M. 234, 242, 880 P.2d 845, 853 (1994)  "The words of a statute&nbsp;... should be given their ordinary meaning, absent clear and express legislative intention to the contrary", as long as the ordinary meaning does "not render the statute's application absurd, unreasonable, or unjust." ''State v. Rowell'', 121 N.M. 111, 114, 908 P.2d 1379, 1382 (1995) When the meaning of a statute is unclear or ambiguous, we have recognized that it is "the high duty and responsibility of the judicial branch of government to facilitate and promote the legislature's accomplishment of its purpose." ''State ex rel. Helman v. Gallegos'', 117 N.M. 346, 353, 871 P.2d 1352, 1359 (1994);  ''New Mexico v. Juan'', 2010-NMSC-041, August 9, 2010
* [[California Court of Appeals]], 4th District: "Our role in construing a statute is to ascertain the intent of the Legislature so as to effectuate the purpose of the law. (''People v. Jefferson'' (1999) 21 Cal.4th 86, 94 [86 Cal.Rptr.2d 893, 980 P.2d 441].) Because the statutory language is generally the most reliable indicator of that intent, we look first at the words themselves, giving them their usual and ordinary meaning. (''People v. Lawrence'' (2000) 24 Cal.4th 219, 230 [99 Cal.Rptr.2d 570, 6 P.3d 228].) We do not, however, consider the statutory language in isolation, but rather examine the entire substance of the statute in order to determine the scope and purpose of the provision, construing its words in  context and harmonizing its various parts. (''People v. Acosta'' (2002) 29 Cal.4th 105, 112 [124 Cal.Rptr.2d 435, 52 P.3d 624].)" ''Alford v. Superior Court'' (People) (2003) 29 Cal.4th 1033, 1040
*[[United States Court of Appeals for the Second Circuit]]: "As in all statutory construction cases, we begin with the language of the statute. The first step is to determine whether the language at issue has a plain and unambiguous meaning with regard to the particular dispute in the case." ''[[Barnhart v. Sigmon Coal Co.]]'', 534 U.S. 438, 450 (2002); "[U]nless otherwise defined, statutory words will be interpreted as taking their ordinary, contemporary,  common meaning." ''United States v. Piervinanzi'', 23 F.3d 670, 677 (2nd Cir. 1994).
*[[Maryland Court of Appeals]]: "[W]e begin our analysis by reviewing the pertinent rules of [statutory construction]. Of course, the cardinal rule is to ascertain and effectuate legislative intent. To this end, we begin our inquiry with the words of the statute and, ordinarily, when the words of the statute are clear and unambiguous, according to their commonly understood meaning, we end our inquiry there also." ''Chesapeake and Potomac Telephone Co. of Maryland v. Director of Finance for Mayor and City Council of Baltimore'', 343 Md. 567, 683 A.2d 512 (1996)
* [[Indiana Court of Appeals]]: "The first and often last step in interpreting a statute is to examine the language of the statute. We will not, however, interpret a statute that is clear and unambiguous on its face."  ''Ashley v. State'', 757 N.E.2d 1037, 1039, 1040 (2001).

====Internal and external consistency====
It is presumed that a statute will be interpreted so as to be internally consistent. A particular section of the statute shall not be divorced from the rest of the act. The '''''ejusdem generis''''' (or ''eiusdem generis'', Latin for "of the same kind") rule applies to resolve the problem of giving meaning to groups of words where one of the words is ambiguous or inherently unclear. The rule states that where "general words follow enumerations of particular classes or persons or things, the general words shall be construed as applicable only to persons or things of the same general nature or kind as those enumerated".<ref>[https://case-law.vlex.com/vid/walling-v-peavy-wilson-887696670 ''Walling v. Peavy-Wilson Lumber Co., No 213''], 49 F. Supp. 846, 859 (W.D. La. 1943), where the issue involved interpretation of the words "board, lodging, or other facilities"</ref>

A statute shall not be interpreted so as to be inconsistent with other statutes. Where there is an apparent inconsistency, the judiciary will attempt to provide a harmonious interpretation.{{example needed|date=November 2022}}

====Statements of the legislature====
Legislative bodies themselves may try to influence or assist the courts in interpreting their laws by placing into the legislation itself statements to that effect. These provisions have many different names, but are typically noted as:
* ''Recitals'';<ref>{{cite web
 |url         = http://eur-lex.europa.eu/en/techleg/10.htm

}} 
</ref>
* ''Findings'';
* ''Declarations'', sometimes suffixed with ''of Policy'' or ''of Intent''; or
* ''Sense of Congress'', or of either house in multi-chamber bodies.

In most legislatures internationally, these provisions of the bill simply give the legislature's goals and desired effects of the law, and are considered non-substantive and non-enforceable in and of themselves.<ref>Norman J. Singer, ''Sutherland Statutory Construction'', 6th Edition, Vol. 1A, §20.12 (West Group 2000)</ref><ref>''American Jurisprudence'' 2d<!-- 2nd edition? -->, Vol. 73, "Statutes" (West Group 2001)</ref>

However in the case of the European Union, a supranational body, the recitals in Union legislation must specify the reasons the operative provisions were adopted, and if they do not, the legislation is void.<ref name="Klimas & Vaiciukaite 2008">Klimas, Tadas and Vaiciukaite, Jurate, "The Law of Recitals in European Community Legislation" (July 14, 2008). ''ILSA Journal of International & Comparative Law'', Vol. 15, 2008. {{SSRN|1159604}}</ref> This has been interpreted by the courts as giving them a role in statutory interpretation with Klimas, Tadas and Vaiciukaite explaining "recitals in EC law are not considered to have independent legal value, but they can expand an ambiguous provision's scope. They cannot, however, restrict an unambiguous provision's scope, but they can be used to determine the nature of a provision, and this can have a restrictive effect."<ref name="Klimas & Vaiciukaite 2008"/>

== Canons ==

Also known as canons of construction, canons give common sense guidance to courts in interpreting the meaning of statutes. Most canons emerge from the [[common law]] process through the choices of judges. Critics{{who|date=February 2022}} of the use of canons argue that the canons constrain judges and limit the ability of the courts to [[judicial activism|legislate from the bench]]. Proponents{{who|date=February 2022}} argue that a judge always has a choice between competing canons that lead to different results, so judicial discretion is only hidden through the use of canons, not reduced. 
These canons can be divided into two major groups:

# Textual canons 
# Substantive canons

{{Incomplete list|date=February 2021}}

===Textual canons===

Textual canons are rules of thumb for understanding the words of the text. Some of the canons are still known by their traditional [[Latin]] names.

;    Plain meaning: When writing statutes, the legislature intends to use ordinary English words in their ordinary senses. The United States Supreme Court discussed the [[plain meaning rule]] in ''Caminetti v. United States'',<ref>''Caminetti v. United States'', [[Case citation|242 U.S. 470]] (1917)</ref>  reasoning "[i]t is elementary that the meaning of a statute must, in the first instance, be sought in the language in which the act is framed, and if that is plain&nbsp;... the sole function of the courts is to enforce it according to its terms." And if a statute's language is plain and clear, the Court further warned that "the duty of interpretation does not arise, and the rules which are to aid doubtful meanings need no discussion". This means that the plain meaning rule (and statutory interpretation as a whole) should only be applied when there is an ambiguity. Because the meaning of words can change over time, scholars and judges typically will recommend using a dictionary to define a term that was published or written around the time the statute was enacted. 
;    Technical meaning: As opposed to the plain meaning rule, the technical meaning rule applies the specific context and rules of grammar that are applied if the term is well defined and understood in an industry setting. To determine if there is a technical meaning, judges will look at whether the surrounding words are technical, and whether the act was directed to a technical audience.<ref name=":1">{{Cite web |title=Nix v. Hedden, 149 U.S. 304 (1893) |url=https://supreme.justia.com/cases/federal/us/149/304/ |access-date=2023-04-14 |website=Justia Law |language=en}}</ref> They can also look to the title, the purpose, or the legislative history to indicate whether there is technical meaning implied in the statute.<ref name=":1" /> This concept is most easily defined in the case ''Frigaliment Importing Co. v.

;    ''Ejusdem generis'' ("of the same kinds, class, or nature"): When a list of two or more specific descriptors is followed by more general descriptors, the otherwise wide meaning of the general descriptors must be restricted to the same class, if any, of the specific words that precede them.<ref>{{cite encyclopedia |last1=Singer|first1=Norman J. |last2=Singer |first2=J.

This canon is not favored by most scholars, lawyers, or judges. 
;    ''Noscitur a sociis'' ("a word is known by its associates"): When a word is ambiguous, its meaning may be determined by reference to the rest of the statute. This canon is often used to narrow the interpretation of terms in a list. We understand words in an act, particularly listed in words, by considering the words surrounding them. If two or more words grouped together have similar meaning, but are not equally comprehensive, a more general word will be limited and qualified by a more specific one.<ref>See generally, {{cite encyclopedia |last1=Singer|first1=Norman J. |last2=Singer |first2=J.

;    ''Reddendo singula singulis'' ("rendering each to each"): "When a will says "I devise and bequeath all my real and personal property to A", the principle of reddendo singula singulis would apply as if it read "I devise all my real property, and bequeath all my personal property, to A", since the word devise is appropriate only to real property and the term bequeath is appropriate only to personal property."<ref>{{Cite web|url = http://definitions.uslegal.com/r/reddendo-singula-singulis/|title = US Legal definitions}}</ref>
;    ''Generalia specialibus non derogant'' ("the general does not derogate from the specific"): {{main|lex specialis}} Described in ''The Vera Cruz''<ref>''The Vera Cruz'', (1884) 10 [[Appeal Cases Law Reports|App Cas]] 59</ref> as: "Now if anything be certain it is this, that where there are general words in a later Act capable of reasonable and sensible application without extending them to subjects specially dealt with by earlier legislation, you are not to hold that earlier legislation indirectly repealed, altered, or derogated from merely by force of such general words, without any evidence of a particular intention to do so." This means that if a later law and an earlier law are potentially—but not necessarily—in conflict, courts will adopt the reading that does not result in an implied repeal of the earlier statute.  Lawmaking bodies usually need to be explicit if they intend to repeal an earlier law.

===Substantive canons===

Substantive canons instruct the court to favor interpretations that promote certain values or policy results.

;    ''Charming Betsy'' canon : National statute must be construed so as not to conflict with international law.  See [https://constitutionallawreporter.com/2015/10/06/historical-charming-betsy-and-constitutional-law-2/ ''Murray v. The Charming Betsy''], [[case citation|6 U.S. (2 Cranch) 64]]  (1804):  "It has also been observed that an act of Congress ought never to be construed to violate the law of nations if any other possible construction remains&nbsp;..."
;    Interpretation in light of fundamental values : Statute does not violate fundamental societal values. See, for example, ''[[Holy Trinity Church v. United States]]'',<ref>''Holy Trinity Church v. United States'' [[case citation|143 U.S. 457]] (1892)</ref> or ''Coco v The Queen'' (Australia).<ref>{{cite AustLII|HCA|15|1994|litigants=Coco v The Queen |parallelcite=(1994) 179 [[Commonwealth Law Reports|CLR]] 427 |courtname=auto}}.</ref> However, legislation that is intended to be consistent with fundamental rights can be overridden by clear and unambiguous language.<ref>{{cite AustLII|HCA|40|2004|litigants=Electrolux Home Products Pty Ltd v Australian Workers' Union |parallelcite=(2004) 221 [[Commonwealth Law Reports|CLR]] 309 |date=2 September 2004 |courtname=auto}}.</ref>
;    [[Rule of lenity]] : In construing an ambiguous criminal statute, the court should resolve the ambiguity in favor of the defendant.<ref name="Rule of Lenity - Economist">{{cite news | url=https://www.economist.com/blogs/democracyinamerica/2015/11/child-pornography-and-law | title=A man's jail term turns on a comma | newspaper=The Economist | date=4 November 2015 | access-date=9 November 2015}}</ref><ref>{{cite book |last1=Scalia |first1=Antonin  |last2=Garne |first2=Bryan A.  |date=2012 |title=Reading Law: The Interpretation of Legal Texts|publisher=Thomson/West |isbn=9780314275554 |quote=Blurred signposts to criminality will not suffice to create it.}}</ref>{{rp|296–302}}  See ''McNally v. United States'';<ref>''McNally v. United States'', 483 U.S. 350 (1987)</ref> ''Muscarello v. U.S.''<ref>''Muscarello v. U.S.'' , 524 U.S. 125 (1998)</ref> (declining to apply the rule of lenity); ''Evans v. U.S.'';<ref>''Evans v. U.S.'', 504 U.S. 255 (1992) (Thomas, J., dissenting)</ref> ''Scarborough v. U.S.'';<ref>''Scarborough v. U.S.'', 431 U.S. 563 (1977) (Stewart, J., dissenting);</ref> ''United States v. Santos'' (2008). This is almost a junior version of the vagueness doctrine, and can be used for both criminal or civil penalty. 
;    Avoidance of abrogation of state sovereignty (United States): See ''[[Gregory v. Ashcroft]]'';<ref>''Gregory v. Ashcroft'' 501 U.S. 452 (1991)</ref> see also ''Gonzales v. Oregon'';<ref>''Gonzales v. Oregon'' 546 U.S. 243 (2006)</ref> see also ''[[Nevada Department of Human Resources v. Hibbs]]'',<ref>''Nevada Department of Human Resources v. Hibbs'' 538 U.S. 721 (2003)</ref> except where such would deprive the defendant of bedrock, foundational rights that the federal government intended to be the minimum floor that the states were not allowed to fall beneath: ''Dombrowski v Pfister''.<ref>''Dombrowski v Pfister'', 380 U.S. 479 (1965).</ref>
;    'Indian' canon (United States): National statute must be construed in favor of Native Americans. See ''[[Chickasaw Nation v. United States]]'':<ref>[https://www.law.cornell.edu/supct/html/00-507.ZS.html ''Chickasaw Nation v. United States''], [[case citation|534 U.S. 84]]  (2001)</ref>  "statutes are to be construed liberally in favor of Indians with ambiguous provisions interpreted to their benefit." This canon can be likened to the doctrine of {{lang|la|[[contra proferentem]]}} in contract law.

===Deference===

Deference canons instruct the court to defer to the interpretation of another institution, such as an administrative agency or Congress. These canons reflect an understanding that the judiciary is not the only branch of government entrusted with constitutional responsibility.

;    Deference to administrative interpretations (US ''Chevron'' deference): If a statute administered by an agency is ambiguous with respect to the specific issue, the courts will defer to the agency's reasonable interpretation of the statute. This rule of deference was formulated by the [[Supreme Court of the United States|United States Supreme Court]] in [[Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc.|''Chevron v. Natural Resources Defense Council'']].<ref>''Chevron v. Natural Resources Defense Council'', [[Case citation|467 U.S. 837 (1984)]]</ref>  On June 28, 2024, in the landmark case [[Loper Bright Enterprises v. Raimondo]], the United States Supreme Court explicitly overturned the doctrine of Chevron deference.  The case was cited as precedent in a federal case (Tennessee v. Becerra) the very next week.  Loper says, in part, "Chevron is overruled. Courts must exercise their independent judgment in deciding whether an agency has acted within its statutory authority, as the APA [Administrative Procedures Act] requires."

;    Avoidance canon (canon of constitutional avoidance): If a statute is susceptible to more than one reasonable construction, courts should choose an interpretation that avoids raising constitutional problems. In the US, this canon has grown stronger in recent history. The traditional avoidance canon required the court to choose a different interpretation only when one interpretation was actually unconstitutional. The modern avoidance canon tells the court to choose a different interpretation when another interpretation merely raises constitutional doubts.<ref>Einer Elhauge (2008). ''Statutory Default Rules: How to Interpret Unclear Legislation''. [[Harvard University Press]]. [https://books.google.com/books?id=l4A0BVUeYHsC&pg=PA237 pp. 237–239]. {{ISBN|978-0-674-02460-1}}.</ref><ref>''United States v. Jin Fuey Moy'', 241 U.S. 394, 401 (1916).</ref>

The avoidance canon was discussed in ''Bond v. United States'' when the defendant placed toxic chemicals on frequently touched surfaces of a friend.<ref>''Bond v. US'', 134 S. Ct. 2077, 2085 (2014) (quoting 18 U.S.C. 229(a)(1)(2014). Cited in Brannon, V. C. (2018). ''Statutory Interpretation: Theories, Tools, and Trends'' (CRS Report No. R45153). Congressional Research Service. 29–30.</ref> The statute in question made using a chemical weapon a crime; however, the separation of power between states and the federal government would be infringed upon if the Supreme Court interpreted the statute to extend to local crimes.<ref name=":0">''Bond v. US'', 134 S. Ct. 2077, 2088-2090 (2014) (quoting 18 U.S.C. 229(a)(1)(2014). Cited in Brannon, V. C. (2018). ''Statutory Interpretation: Theories, Tools, and Trends'' (CRS Report No. R45153). Congressional Research Service. 30.</ref> Therefore, the Court utilized the canon of constitutional avoidance and decided to "read the statute more narrowly, to exclude the defendant's conduct".<ref>''Bond v. US'', 134 S. Ct. 2077, 2093 (2014) (quoting 18 U.S.C. 229(a)(1)(2014). Cited in Brannon, V. C. (2018). ''Statutory Interpretation: Theories, Tools, and Trends'' (CRS Report No. R45153). Congressional Research Service. 30.</ref>

;{{anchor|absurdity}} Avoiding absurdity: The legislature did not intend an absurd or manifestly unjust result.<ref>Einer Elhauge. ''Statutory Default Rules: How to Interpret Unclear Legislation''. [[Harvard University Press]] (2008), [https://books.google.com/books?id=l4A0BVUeYHsC&pg=PA148 p. 148]. {{ISBN|978-0-674-02460-1}}.</ref><ref>''Green v. Bock Laundry Machine Co.'', 490 U.S. 504 (1989).</ref>

The application of this rule in the United Kingdom is not entirely clear. The literal meaning rule – that if "Parliament's meaning is clear, that meaning is binding no matter how absurd the result may seem"<ref>William S Jordan III (1994), ''Legislative History and Statutory Interpretation: The Relevance of English Practice'', 29 USF L Rev 1.</ref> – has a tension with the "golden rule", permitting courts to avoid absurd results in cases of ambiguity. At times, courts are not "concerned with what parliament intended, but simply with what it has said in the statute".<ref>''R v Hertford College'' [1878] 3 QBD 693, 707 (CA).</ref> Different judges have different views. In ''Nothman v. London Borough of Barnet'', Lord Denning of the Court of Appeals attacked "those who adopt the strict literal and grammatical construction of the words" and saying that the "[t]he literal method is now completely out-of-date [and] replaced by the ... 'purposive' approach".<ref>''Nothman v London Borough of Barnet'' [1978] 1 All E.R. 1243, 1246.</ref> On appeal, however, against Denning's decision, Lord Russell in the House of Lords "disclaim[ed] the sweeping comments of Lord Denning".<ref>[1979] 1 All ER 142, 143 (HL). The judgment, however, was affirmed on the basis of the statutory language regardless.</ref>

For jurisprudence in the United States, "an absurdity is not mere oddity. The absurdity bar is high, as it should be. The result must be preposterous, one that 'no reasonable person could intend{{'"}}.<ref>''Texas Brine Co. LLC v. American Arbitration Association'', 955 F.3d 482, 486 (2020).</ref><ref>{{Cite book|last1=Scalia|first1=Antonin|title=Reading Law: the interpretation of legal texts|last2=Garner|first2=Bryan|publisher=Thomson Reuters|year=2012|pages=237}}</ref> Moreover, the avoidance applies only when "it is quite impossible that Congress could have intended the result&nbsp;... and where the alleged absurdity is so clear as to be obvious to most anyone".<ref>''Catskill Mountains Chapter of Trout Unlimited, Inc. v. United States EPA'', 846 F.3d 492, 517 (2d Cir. 2017) (quoting ''Public Citizen v. U.S. Department of Justice'', 491 U.S. 440, 470–71 (1989) (Kennedy, J., concurring in the judgment)).</ref> "To justify a departure from the letter of the law upon that ground, the absurdity must be so gross as to shock the general moral or common sense",<ref>''Crooks v. Harrelson'', 282 U.S. 55, 60 (1930).</ref> with an outcome "so contrary to perceived social values that Congress could not have 'intended' it".<ref>John F Manning, 'The absurdity doctrine' (2003) 116 Harv L Rev 2387, 2390.</ref>

;    [[Clear statement rule]] : When a statute may be interpreted to abridge long-held rights of individuals or states, or make a large policy change, courts will not interpret the statute to make the change unless the legislature clearly stated it. This rule is based on the assumption that the legislature would not make major changes in a vague or unclear way, and to ensure that voters are able to hold the appropriate legislators responsible for the modification.
;    {{lang|la|Leges posteriores priores contrarias abrogant}} (Subsequent laws repeal those before enacted to the contrary, aka "Last in Time") : When two statutes conflict, the one enacted last prevails. See [[implied repeal]] and [[derogation]].

===Criticism===
Critics of the use of canons argue that canons impute some sort of "omniscience" to the legislature, suggesting that it is aware of the canons when constructing the laws. In addition, it is argued that the canons give a credence to judges who want to construct the law a certain way, imparting a false sense of justification to their otherwise arbitrary process. In a classic article, [[Karl Llewellyn]] argued that every canon had a "counter-canon" that would lead to the opposite interpretation of the statute.<ref>Karl N. Llewellyn, Remarks on the Theory of Appellate Decision and the Rules of Canons About How Statutes are to be Construed, 3 Vand. L. Rev. 395 (1950) republished with permission in 5 Green Bag 297 (2002).</ref><ref>{{cite journal |last1=Nourse |first1=Victoria F. |title=The Canon Wars |journal=Texas Law Review |date=2018 |volume=97 |issue=1 |url=https://texaslawreview.org/wp-content/uploads/2018/11/Krishnakumar.PRINTINGpdf.pdf |access-date=October 5, 2022 |archive-date=November 30, 2018 |archive-url=https://web.archive.org/web/20181130151437/https://texaslawreview.org/wp-content/uploads/2018/11/Krishnakumar.PRINTINGpdf.pdf |url-status=bot: unknown }}</ref>

Some scholars argue that interpretive canons should be understood as an open set, despite conventional assumptions that traditional canons capture all relevant language generalizations. Empirical evidence, for example, suggests that ordinary people readily incorporate a "nonbinary gender canon" and "quantifier domain restriction canon" in the interpretation of legal rules.<ref>{{cite journal |last1=Tobia |first1=Kevin |last2=Slocum |first2=Brian G. |last3=Nourse |first3=Victoria F. |date=2022 |title=Statutory Interpretation from the Outside |url=https://columbialawreview.org/wp-content/uploads/2022/01/Tobia-Slocum-Nourse-Statutory_Interpretation_From_The_Outside_.pdf |url-status=bot: unknown |journal=Columbia Law Review |volume=122 |archive-url=https://web.archive.org/web/20240229234539/https://columbialawreview.org/wp-content/uploads/2022/01/Tobia-Slocum-Nourse-Statutory_Interpretation_From_The_Outside_.pdf |archive-date=February 29, 2024 |access-date=November 15, 2024}}</ref> 

Other scholars argue that the canons should be reformulated as "canonical" or archetypical queries helping to direct genuine inquiry rather than purporting to somehow help provide answers in themselves. <ref>Harold Anthony Lloyd, 'Recasting Canons of Interpretation and Construction into 'Canonical' Queries: Further Canonical Queries of Presented or Transmitted Text' (2023) 58 Wake Forest L Rev 1047, 1047-1086 https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4369755.</ref>

==European thought==
{{anchor|European perception}}
The French philosopher [[Montesquieu]] (1689–1755) believed that courts should act as "the mouth of the law", but soon it was found that some interpretation is inevitable. 
Following the German scholar [[Friedrich Carl von Savigny]] (1779–1861) the four main interpretation methods are:
* Grammatical interpretation: using the literal meaning of the statutory text.
* Historical interpretation: using the legislative history, to reveal the intent of the legislator. 
* Systematic interpretation: considering the context of provisions, if only by acknowledging in which chapter a provision is listed.  
* Teleological interpretation: considering the ''purpose'' of the statute ({{langx|la|ratio legis}}), as it appears from legislative history, or other observations.
It is controversial{{Citation needed|date=March 2016}} whether there is a hierarchy between interpretation methods. Germans prefer a "grammatical" (literal) interpretation, because the statutory text has a democratic legitimation, and "sensible" interpretations are risky, in particular in view of German history. "Sensible" means different things to different people. The modern, common-law perception that courts actually ''make'' law is very different. In a German perception, courts can only ''further'' develop law ({{lang|de|Rechtsfortbildung}}).

All of the above methods may seem reasonable: 
* It may be considered undemocratic{{Citation needed|date=March 2016}} to ignore the literal text, because only that text was passed through democratic processes. Indeed, there may be no single legislative "intent" other than the literal text that was enacted by the legislature, because different legislators may have different views about the meaning of an enacted statute. It may also be considered unfair to depart from the literal text because a citizen reading the literal text may not have fair notice that a court would depart from its literal meaning, nor fair notice as to what meaning the court would adopt. It may also be unwise{{Citation needed|date=March 2016}} to depart from the literal text if judges are generally less likely than legislatures to enact wise policies.  
* But it may also seem unfair{{Citation needed|date=March 2016}} to ignore the intent of the legislators, or the system of the statutes. So for instance in Dutch law, no general priority sequence for the above methods is recognized.

The freedom of interpretation varies by area of law. Criminal law and tax law must be interpreted very strictly, and never to the disadvantage of citizens,{{Citation needed|date=March 2016}} but liability law requires more elaborate interpretation, because here (usually) both parties are citizens. Here the statute may even be interpreted {{lang|la|contra legem}} in exceptional cases, if otherwise a patently unreasonable result would follow.

==International treaties==
The interpretation of international treaties is governed by another treaty, the [[Vienna Convention on the Law of Treaties]], notably Articles 31–33. Some states (such as the United States) are not a parties to the treaty, but recognize that the Convention is, at least in part, merely a codification of customary international law.

The rule set out in the Convention is essentially that the text of a treaty is decisive unless it either leaves the meaning ambiguous, or obscure, or leads to a result that is manifestly absurd or unreasonable. Recourse to "supplementary means of interpretation" is allowed only in that case, like the preparatory works, also known by the French designation of ''[[travaux préparatoires]]''.

==Statutory interpretation methods==
Within the United States, [[purposivism]] and [[textualism]] are the two most prevalent methods of statutory interpretation.<ref>{{cite journal |last1=Calabresi |first1=Guido |title=An Introduction to Legal Thought: Four Approaches to Law and to the Allocation of Body Parts |journal=Stanford Law Review |date=2003 |volume=55 |issue=6 |pages=2113–2151 |pmid=12908477 }}</ref> Also recognized is the theory of intentionalists, which is to prioritize and consider sources beyond the text.

"Purposivists often focus on the legislative process, taking into account the problem that Congress was trying to solve by enacting the disputed law and asking how the statute accomplished that goal."<ref>{{cite journal |last1=Hart & Sacks |first1=Henry M. & Albert M. |title=The Legal Process: Basic Problems in the Making and Application of Law |journal=William N. Eskridge Jr. & Phillip P. Frickey Eds. |date=1994 |pages=1148}}</ref> Purposivists believe in reviewing the processes surrounding the power of the legislative body as stated in the constitution as well as the rationale that a "reasonable person  conversant with the circumstances underlying enactment would suppress the mischief and advance the remedy"<ref name="What Divides Textualists from Purpo">{{cite journal |last1=Manning |first1=John F. |title=What Divides Textualists from Purposivists? |journal=SSRN Electronic Journal |date=2006 |volume=106 |issue=70 |doi=10.2139/ssrn.2849247}}</ref>  Purposivists would understand statutes by examining "how Congress makes its purposes known, through text and reliable accompanying materials constituting legislative history."<ref>{{cite book |last1=Katzmann |first1=Robert A. |title=Judging statutes |date=2014 |publisher=Oxford university press |location=Oxford |isbn=9780199362134 |page=104 |edition=1st}}</ref><ref name="auto"/>

"In contrast to purposivists, textualists focus on the words of a statute, emphasizing text over any unstated purpose."<ref>{{cite journal |last1=Taylor |first1=George H. |title=Structural Textualism |journal=B.U. L. Rev. |date=1995 |pages=321, 327}}</ref>

Textualists believe that everything which the courts need in deciding on cases are enumerated in the text of legislative statutes. In other words, if any other purpose was intended by the legislature then it would have been written within the statutes and since it is not written, it implies that no other purpose or meaning was intended. By looking at the statutory structure and hearing the words as they would sound in the mind of a skilled, objectively reasonable user of words,<ref>{{cite journal |last1=Easterbrook |first1=Frank |title=The Role of Original Intent in Statutory Construction |journal=Harvard Journal of Law and Public Policy |date=1 January 1988 |volume=11 |pages=59 |url=https://chicagounbound.uchicago.edu/journal_articles/1155/}}</ref> textualists believe that they would respect the constitutional separation of power and best respect [[Parliamentary sovereignty|legislative supremacy]].<ref name="What Divides Textualists from Purpo"/> Critiques of modern textualism on the United States Supreme Court abound.<ref>{{cite journal|last1=Eskridge|first1=William N.|last2=Nourse|first2=Victoria F.|title=Textual Gerrymandering: The Eclipse of Republican Government in an Era of Statutory Populism|journal=New York University Law Review|date=2021|volume=96|url=https://www.nyulawreview.org/wp-content/uploads/2021/12/EskridgeNourse-ONLINE.pdf|access-date=October 5, 2022|archive-date=December 28, 2021|archive-url=https://web.archive.org/web/20211228200410/https://www.nyulawreview.org/wp-content/uploads/2021/12/EskridgeNourse-ONLINE.pdf|url-status=bot: unknown}}</ref><ref>{{cite journal|last1=Nourse|first1=Victoria F.|title=Textualism 3.0: Statutory Interpretation After Justice Scalia|journal=Alabama Law Review|date=2019|volume=70|issue=3|url=https://www.law.ua.edu/lawreview/files/2019/05/2-Nourse-FINAL.pdf|archive-url=https://web.archive.org/web/20200713104455/https://www.law.ua.edu/lawreview/files/2019/05/2-Nourse-FINAL.pdf|url-status=dead|archive-date=July 13, 2020|access-date=October 5, 2022}}</ref>

Intentionalists refer to the specific intent of the enacting legislature on a specific issue. Intentionalists can also focus on general intent. It is important to note that private motives do not eliminate the common goal that the legislature carries. This theory differs from others mainly on the types of sources that will be considered. Intentional theory seeks to refer to as many different sources as possible to consider the meaning or interpretation of a given statute. This theory is adjacent to a contextualist theory, which prioritizes the use of context to determine why a legislature enacted any given statute.
