To avoid ambiguity, legislatures often include "definitions" sections within a statute, which explicitly define the most important terms used in that statute. But some statutes omit a definitions section entirely, or (more commonly) fail to define a particular term. The plain meaning rule attempts to guide courts faced with
litigation that turns on the meaning of a term
not defined by the statute, or on that of a word found within a definition itself. According to the plain meaning rule, absent a contrary definition within the statute, words must be given their plain, ordinary and literal meaning. If the words are clear, they must be applied, even though the intention of the legislator may have been different or the result is harsh or undesirable. The literal rule is what the law says instead of what the law was intended to say.
Larry Solum, Professor of Law at Georgetown University, expands on this premise:
Soft plain meaning rule Justices normally impose an absurdity limit on this rule, which states that a statute cannot be interpreted literally if it would lead to an absurd result. In the US Supreme Court
Chung Fook v. White (1924) marked the beginning of the looser American Rule that the intent of the law was more important than its text. This is sometimes termed the
soft plain meaning rule, where the statute is interpreted according to the ordinary meaning of the language, unless the result would be cruel or absurd. For example, see
Rector, Holy Trinity Church v. United States, 143 U.S. 457 (1892). Even the most vocal supporters of
textualism and the plain meaning rule have been willing to commute "strict" plain meaning to "soft" plain meaning to a certain extent, in some circumstances; see, e.g.
United States v. X-Citement Video, 513 U.S. 64 (1994) (Scalia, J., dissenting): In the United Kingdom, this is referred to as the
golden rule. == Reasons favoured ==
