This document discusses various rules of statutory interpretation used in legal systems, including the literal rule, golden rule, mischief rule, and purposive rule. It provides more detail on the mischief rule, explaining that it looks at the "mischief" or wrong that a statute is intended to correct in order to discover Parliament's intention. The mischief rule was established in Heydon's Case from 1584. The document also summarizes the 1874 case Gorris v Scott, where the court used the mischief rule to determine that a statute requiring animal pens on ships was intended to prevent disease, not protect against property loss.
