Court tries to look at intention behind legislation or the problem parliament was trying to fix and then interprets it to give effect to what they want
Mischief rule

Smith v Hughes - soliciting on a balcony, judges held that they were causing the mischief that parliament was trying to avoid by bothering people on the street
Disadvantage of Mischief rule
Judges' interpretation is subjective, potentially not enforcing parliamentary statute
Advantage of Mischief rule
Focuses on the good of the public by avoiding the mischief, more flexible than the literal rule
Literal rule
Interpreting law literally
Literal rule
Lawton v Fleming - Brown, playing football in a park, literal meaning of football was applied
Disadvantage of Literal rule
Not flexible, may not consider the intention behind the words used
Advantage of Literal rule
Respects parliamentary law making and avoids judicial law making
Golden rule

Extension of the literal rule where judges interpret language literally unless it creates an absurdity
Golden rule

R v Allen - prevented bigamy, interpreted 'marry' as 'going through a marriage ceremony'
Advantage of Golden rule
Respects parliamentary law making but avoids unjust outcomes
Purposive approach

Looking for the purpose behind the law, more wide-ranging than other approaches
Intrinsic aids for statutory interpretation
Looking into the statute itself, examining the document to figure out the purpose of the legislation
Extrinsic aids for statutory interpretation
Looking outside the statute itself, considering white and green papers, Law Commission reports, consultation, and parliamentary debates
Use of extrinsic aids

Pepper v Hart - referred to Hansard for the case, R (Crown Rex/Regina) v Hinks - Lord Hutton looked at the way sections of the Theft Act are ordered to help define appropriation
Statutory interpretation involves methods judges use to imply statutes
