Proportionality test in Australian administrative law
Proportionality Test in Australian Administrative Law
What is the Proportionality Test?
The proportionality test is a principle used by courts to review administrative decisions, ensuring that any restriction or action by the government is appropriate and not excessive relative to the aim pursued. It strikes a balance between individual rights and public interests.
Why is it Important?
Ensures administrative power is exercised fairly and reasonably.
Prevents arbitrary or oppressive decisions.
Protects fundamental rights from disproportionate interference.
Provides a structured framework for judicial review beyond traditional Wednesbury unreasonableness.
Structure of the Proportionality Test
Typically, the test involves four stages:
Legitimate objective: The decision must pursue a legitimate aim.
Suitability: The means used must be suitable to achieve the aim.
Necessity: There must be no less restrictive alternative.
Balancing/Proportionality stricto sensu: The benefits of the decision must outweigh the harm caused.
