ⓘ Rule of lenity

The rule of lenity is a principle of criminal statutory interpretation that requires a court to apply any unclear or ambiguous law in the manner most favorable to the defendant. It has a long history in the law and has been an important element of the relationship between the courts and legislature, although its role in modern jurisprudence is less clear.

                                     

1. Overview

Today, determining legislative intent is a critical job that arises from the distinct and separate roles played by the judiciary and the legislature in administering justice. Judges are routinely required to apply the relevant laws and rules passed by the legislature to the decisions they make. There are reasons this can be difficult.

For one, laws are intended to apply generally and it would be impossible for the legislature to foresee all the possible situations to which they might apply after their enactment. Second, the manner in which laws are passed, which includes the influence of lobbying and interest groups, can sometimes obscure their purpose when finally enacted. Finally, the two branches are not allowed to "confer" with one another. Neither is the legislature allowed to add to a law it has already passed in order to affect a courts ruling, nor are the courts allowed to "inquire" as to how a law should be applied in the cases before them.

The two institutions have evolved tools to make the job easier. For instance, statutes often contain "definition" sections, which attempt to make plain how the statute should be read. The courts have developed "canons of construction", rules which are intended to guide the manner in which a statute is to be applied.

The rule of lenity is one such canon. Implicit in its provisions is the additional burden placed on the prosecution in a criminal case and the protection of individual rights against the powers of the state. It also furthers the fundamental principle of requiring notice in criminal law. Individuals should not be punished for their acts when the law fails to communicate to the public that such acts are forbidden.

It is intended only to apply to those instances where the court recognizes the existence of more than one interpretation and where the decision that the court reaches harms or benefits the defendant to some greater or lesser degree. In that case, the rule requires the court to select the interpretation most beneficial or least detrimental to the defendant.

                                     

2.1. History English common law

Originally, the rule was conceived by English judges trying to limit Parliaments use of the death penalty. When the facts of a case were not expressly described by a law, the court would "strictly construe" it so as to exclude its application to the case in question.

A 1547, a law passed that denied a lesser sentence to first-time offenders convicted of "felonious stealing of Horses, Geldings or Mares" among other offenses. The courts interpreted the law as only applying to those convicted of stealing two or more horses and allowed first-offenders who stole one horse to continue to avail themselves of the lesser penalty. The following year, Parliament explicitly addressed the rules use with the passage of a new law, solely dedicated to horse thievery. They pointed to the prior laws "ambiguous" wording and its construction by the courts. The new law explicitly stated that those convicted of stealing "any Horse, Gelding, or Mare" shall be treated the same as those charged with "stealing two Horses, two Geldings, or two Mares, or any other".

Under the reign of George II, another law concerning first-offenders and livestock was similarly limited by the courts. This time, the act ambiguously referred to "Sheep, or other Cattle." Again, the following year, Parliament passed a new "Act to Explain An Act". In it, they expressly spell out that it shall apply to "any Bull, Cow, Ox, Steer, Bullock, Heifer, Calf and Lamb, as well as sheep".

                                     

2.2. History Early American law

Laying out the rules application in the American courts, it was first cited in 1820 by Chief Justice John Marshall in United States v. Wiltberger:

The rule that penal laws are to be construed strictly, is perhaps not much less old than construction itself. It is founded on the tenderness of the law for the rights of individuals; and on the plain principle, that the power of punishment is vested in the legislative, not in the judicial department.

.

. The rule comes into operation at the end of the process of interpreting what Congress has expressed, not at the beginning as an overriding consideration of being lenient to wrongdoers.

                                     

3. Modern status in the U.S.

The rule is today seen as an expression of legislative supremacy. It is infrequently cited in contemporary opinions.

During oral arguments for the 2016 case, Lockhart v. United States, Justice Antonin Scalia sua sponte raised the question of the rules application:

". what I worry about is the rule of lenity. You have these dueling canons, and you have a rule that when the government sends somebody to jail for 10 years, it has to cross sharp corners. It has to dot every i and cross every t. It has to be clear!"

In the end, he joined the majority in refusing to apply the rule.

In State v. Thonesavanh, The Minnesota Supreme Court expressly rejected the position that the rule ".allows a defendant to prevail in every instance in which a criminal statute is ambiguous." At issue was the question of whether the word "take" as used in the states law against auto theft required the accused to actually move the vehicle, or, as in the case before them, merely to enter it and lock the doors. The court relied on the doctrine of in pari materia in holding that the mere "temporary control" of the car was enough under the statue.

On the other hand, the Massachusetts Supreme Judicial Court cited the rule in Commonwealth vs. Dayton, in ruling that the ambiguous language in the states OUI law did not permit a suspect to be held without bail unless they have been convicted three times under the statute, as opposed to merely being arrested three times.



                                     

3.1. Modern status in the U.S. State codification

The states of Florida and Ohio have codified the rule. The Florida statute states that the code "shall be strictly construed; when the language is susceptible of differing constructions, it shall be construed most favorably to the accused." The Ohio law states simply that offenses and penalties shall be "strictly construed against the state and liberally construed in favor of the accused."

A greater number of states, however, have statutorily eliminated the rule.
