Proportionality in Australian administrative law
Proportionality in Australian Administrative Law
What is Proportionality?
Proportionality is a principle used by courts to assess whether a public authority's action or decision is justified, balancing the means used against the ends sought.
It ensures that administrative decisions are not excessive, arbitrary, or oppressive but rather appropriate and necessary to achieve legitimate objectives.
The principle is often invoked in judicial review when a decision affects individual rights or interests, especially in contexts involving fundamental rights, freedoms, or legitimate expectations.
How Proportionality Operates:
The test typically involves three or four stages:
Legitimate Purpose: The decision must pursue a legitimate objective within the powers granted.
Suitability: The measure adopted must be suitable or rationally connected to achieving that purpose.
Necessity: There should be no less restrictive alternative available to achieve the same result.
Balance (Proportionality stricto sensu): The benefits of the measure must outweigh the detriment caused to the affected individual.
