Golden Rule

The golden rule is used if the literal rule produces an absurdity, therefore the court should look for another meaning of the words that avoids the absurd result.

Narrow Approach - This is where a word in the statute has more than one meaning and leads the judge to select the meaning which avoids absurdity.

Wide Approach - This is where the words in the statute have one meaning however to interpret them as such would cause injustuce or absurdity, which is contrary to the intentions of Parliament.


  • R v Allen [1872] - Offence Against the Person Act 1861 - Bigamy is an offence
  • Adler v George [1964] - Official Secrets Act 1920 - offence to obstruct an officer "in the vicinity of a prohibited place"
  • Re Sigworth [1935] - The Administrations of Estates Act 1925 - distributes of the property of an interstate amongst next of kin

Mischief Rule

The judge looks at the reason for the Act and what the problem or 'mischief' the law was intended to remedy. Established in Heydon's Case [1584]. When applying mischief rule, court must consider:

  • What was the common law before making the Act?
  • What was teh mischief and defect for which the common law didn't provide?
  • What was the remedy Parliament passed to cure the mischief?


  • Smith v Hughes [1960] - The Street Offences Act 1959 - offence to "solicit in a street or public place for the purpose of prostitution"
  • Royal College of Nursing v DHSS [1981] - The Abortion Act 1967 - abotions had to be done by a "registered medical practitioner"

Mischief Rule - Advantages and disadvantages


  • Gives effect to the true intention of Parliament.
  • Looking at words only is inadequate. Judges ecamine what the statute was passed to prevent.
  • Judges interpret Act in light of changing social, economical and technological circumstances.
  • Law Commission in 1969 said Mischief Rule is a 'rather more satisfactory approach'


  • At the time of Heydon's Case statutes started by explaining why they have been written and they were written by judges.
  • Goes against parliamentary supremacy as judges are effectively rewriting statutes.
  • Finding the intention isn't always easy.
  • Judges may use their own views o how the law should remedy a mischief.
  • Rule can lead to uncertainty. Therefre difficult for lawyers to advise clients.
  • Can change the meaning of what an Act says.
