The principle of proportionality in administrative decision-making
📘 The Principle of Proportionality in Administrative Decision-Making
📌 What is the Principle of Proportionality?
The principle of proportionality is a fundamental legal principle in administrative law that ensures that any action taken by a public authority must be:
Suitable to achieve the intended legitimate aim,
Necessary in that there is no less restrictive alternative available, and
Reasonable and balanced such that the benefits of the action outweigh the harm caused.
This principle acts as a check against excessive or arbitrary exercises of power by public authorities.
⚖️ Application in Administrative Decision-Making
Public authorities must ensure their decisions do not go beyond what is required to achieve legitimate objectives.
It prevents overreach and unjustified interference with individual rights.
Commonly applied in human rights cases, regulatory decisions, immigration law, and planning law.
📚 Key Cases on the Principle of Proportionality
1. Bank Mellat v. HM Treasury (No 2) [2013] UKSC 39

The UK Treasury imposed financial sanctions on Bank Mellat due to Iran's nuclear program.
Bank Mellat challenged the sanctions as disproportionate.
Issue:
Were the financial sanctions imposed proportionate to the aim of preventing nuclear proliferation?
Holding:
The Supreme Court held that the sanctions were disproportionate and quashed them.
Reasoning:
The government failed to consider less restrictive alternatives.
The sanctions caused undue harm to the bank’s legitimate business interests.
The court emphasized the need for balancing the public interest and the impact on rights.
Significance:
Reinforced the strict application of proportionality in administrative sanctions.
Demonstrated judicial willingness to scrutinize government decisions affecting economic rights.
2. R (Daly) v. Secretary of State for the Home Department [2001] UKHL 26
Facts:

Reasoning:
The policy was not narrowly tailored to protect security.
Less intrusive measures could have been used.

3. Associated Provincial Picture Houses Ltd. v. Wednesbury Corporation [1948] 1 KB 223
Facts:
Wednesbury Corporation imposed a condition restricting cinema opening times.
The cinema owners claimed the decision was unreasonable and disproportionate.
Issue:
Did the local authority’s decision constitute an unreasonable (disproportionate) exercise of power?
Holding:
The court introduced the concept of “Wednesbury unreasonableness”.
Reasoning:
The court would only intervene if the decision was so unreasonable that no reasonable authority would ever impose it.
While not explicitly called proportionality, this case set early grounds for scrutinizing unreasonable and disproportionate decisions.
Significance:
Though stricter than proportionality, the Wednesbury test remains relevant.
Later cases evolved from Wednesbury unreasonableness towards a more nuanced proportionality approach.
