  • Discussion about implied intergovernmental immunities and reference to a North American case, McCulloch v. Maryland (1819).
  • McCulloch v. Maryland: US Supreme Court devised the theory of implied powers.
    • Implied powers: Existence of an express power implies an incidental power necessary for its exercise.

Theory of Implied Powers

  • If given an express power, it comes with necessary incidental powers.
  • 1955 High Court: Every legislative power carries authority to legislate incidental matters necessary for its main purpose.

Section 5139 of the Australian Constitution
