Citing Extrinsic Materials

Extrinsic materials are documents, defined within a jurisdiction's Interpretation Act, which can used in court to interpret the meaning and intent of legislation.

Section 15AB of the Acts Interpretation Act 1901 (Cth) identifies extrinsic materials as including:

  • reports of Royal Commissions, Law Reform Commissions, and committees of inquiry;
  • treaties and international agreements;
  • explanatory memoranda;
  • parliamentary debates (Hansard), including second reading speeches.
