LAWS1160 Chap.6 Purpose, Considerations and Fettering
Purpose, Considerations and Fettering
Discretion is broad only within the purpose and boundaries of the statute that grants it. An answer on improper purpose, relevant considerations or fettering should therefore begin with statutory construction. Identify the objects, language, structure and consequences of the scheme.
From those features, formulate the authorised end of the power and the matters that the Act requires, permits or forbids the administrator to consider. Improper purpose focuses on why power was exercised. Characterise the actual substantial purpose from the evidence rather than accepting a convenient label.
An administrator may act with several motives, so explain which purpose materially drove the decision and whether it fits the statutory grant. The analysis is stronger when it compares the authorised objective with the practical end pursued, showing why the difference matters under the Act. Considerations doctrine asks a different question.
A mandatory relevant consideration is one the statute requires to be taken into account; an irrelevant consideration is one the scheme prohibits from influencing the decision. Everyday importance is not enough to establish either category. After classification, prove what happened in the actual reasoning.
An omitted mandatory matter must truly have been overlooked, while an alleged irrelevant matter must have materially influenced the exercise of discretion. Fettering concerns responsibility for the individual decision. Policies can promote consistency, efficiency and equal treatment, but they remain subordinate to statute.
A lawful decision-maker may give a policy substantial weight while staying open to exceptional circumstances and arguments for departure. The legal problem arises when a policy is treated as an inflexible rule, when another person dictates the outcome, or when the administrator surrenders the judgment Parliament entrusted to that office. These grounds often overlap on the facts, but they should not be collapsed.
A rigid policy might reveal fettering, import an irrelevant criterion, or pursue an unauthorised purpose. Work through each route separately and tie it to evidence. End with the legal consequence and practical relief, usually lawful reconsideration rather than a court-selected merits result.
The goal is to show exactly how statutory purpose controls discretion, not merely to object that the choice was unwise.\n\nEvidence of actual purpose or influence may come from reasons, correspondence, timing, policy documents and the pattern of decision-making. Use those facts cautiously.
Political attention does not automatically prove an improper purpose, and mention of a factor does not establish that it materially affected the result. Explain the inference and address an innocent statutory explanation before reaching a conclusion.
A compact comparison table can help revision: purpose asks what end power served; considerations ask which matters entered the reasoning; fettering asks who truly exercised judgment and with what openness. Apply all three columns to one scenario, but write separate conclusions.
This method exposes overlaps without merging the tests and makes it easier to choose the strongest ground when exam time requires depth rather than a catalogue.\n\nReasons often support more than one inference, so rank grounds by fit rather than multiplying labels. Lead with the doctrine most directly connected to statutory text and evidence, then state alternatives briefly.
Depth comes from proving purpose, influence or surrendered judgment, not from naming every discretion ground that could be imagined.

Purpose, Considerations and Fettering FAQ
How is statutory purpose identified?
Use text, objects, structure, conditions and consequences to characterise both the authorised end and the administrator's actual substantial purpose. Compare those two propositions directly, and use the evidence to show which practical objective materially drove the exercise of power.
Is every sensible matter legally relevant?
No. Mandatory and prohibited status comes from statutory construction, not everyday usefulness. Then prove whether the matter was ignored or influential. A sensible factor may remain merely permissible, so the answer must identify why this Act gives the consideration a legally controlling status.
Can consistent policy use be lawful?
Yes, if the policy fits the Act and the decision-maker remains open to the individual case. Consistency alone does not establish inflexibility. Look for evidence that departures were genuinely considered, relevant circumstances were assessed, and responsibility remained with the authorised decision-maker.
