Unreasonableness and Irrationality FAQ
Does severe impact prove legal unreasonableness?
Severe impact invites close scrutiny but does not decide the ground. Connect the impact to statutory purpose, evidence, alternatives and explanation, then show why the chosen response lacks a legally intelligible justification rather than merely appearing undesirable.
What is an evident and intelligible justification?
It is a comprehensible connection between the statutory task, available evidence, reasoning process and outcome. The phrase does not require perfect reasons or the court's preferred result. It directs attention to whether the exercise of discretion can be legally explained within the scheme.
Can inadequate reasons establish unreasonableness?
Sparse reasons may reveal a missing logical connection, but brevity alone is not decisive. Read the reasons with the record and statutory context. Detailed reasons can also be unreasonable if they contain a contradiction, ignore the decisive issue or rely on an unsupported inference.
Why must the best justification for the decision be addressed?
A balanced answer tests whether the apparent defect has a lawful explanation grounded in the statute and record. Ignoring that possibility turns analysis into advocacy by adjective. Explain the strongest counteraccount and why it succeeds or fails, rather than assuming the absence of your preferred reasoning.
How do I keep unreasonableness separate from merits review?
State that another outcome was available, then explain why availability alone is insufficient. Focus on a fundamental defect in reasoning or an outcome outside the legally permissible range. The court supervises the boundaries of discretion rather than choosing the result it would have preferred.
Is a harsh decision automatically unreasonable?
No. Harsh impact may be relevant, but the applicant must identify a legal defect in process or outcome within the statutory framework. A court does not intervene simply because another lawful choice would be kinder.
Exam move
Revise legal unreasonableness by starting with the discretion's statutory setting. Record its purpose, breadth, factors and possible consequences before evaluating the decision. A wide discretion may support several outcomes, while a tightly structured power may leave less room. The legal standard is applied inside that framework, not against a free-standing intuition about fairness or proportionality.
Replace evaluative adjectives with diagnostic statements. Instead of writing that a sanction is harsh, identify the evidence, statutory objective and explanatory step that fail to connect it to the maximum response. Instead of calling reasoning irrational, identify the contradiction, unsupported inference or non sequitur.
Each statement should reveal why the defect is serious enough to concern legality rather than ordinary merits disagreement. Use reasons and record together. A short explanation may be adequate when the basis is obvious from undisputed facts. Detailed reasons may be defective if they avoid the decisive issue. Mark every inference and ask what evidence supports it.
Then formulate the strongest lawful justification the administrator could offer and determine whether it appears in the reasons or can properly be understood from context. Practise edge cases by changing impact, evidence and alternatives. Give the same official a range of authorised sanctions and vary the applicant's history.
Explain when an extreme outcome has an intelligible statutory justification and when the relationship breaks down. This teaches that extremity is a signal for scrutiny, not a separate formula that automatically invalidates action. Finish every answer with the merits boundary. Acknowledge that another decision was available and explain why that is not the basis for intervention.
The conclusion should identify a fundamental reasoning or outcome defect within the statute, address any rational counteraccount and state the result in calibrated language. If you cannot articulate the missing legal connection, the argument probably remains a request to reweigh merits.
