Statutory interpretation is the act or process of interpreting and applying legislation. Statutory Interpretation is the process of reading and applying statutory laws, and judges trying to find out the intention of parliament when passing the law. Sometimes the words of a statute have a plain and straightforward meaning. But in most cases, there is some ambiguity or vagueness in the words of the statute that must be resolved by the judge.
Judges in England generally apply three basic rules of statutory interpretation, and similar rules are also used in other common law jurisdictions. The literal rule, the golden rule and the mischief rule
This rule explains what the law is rather than explaining what the law means. In literal rule, the words in a statute are given its plain, ordinary, and literal meaning. While applying the literal rule, the law is read word by word and without diverting from its true meaning.
