British Oxygen Co Ltd v Minister of Technology [1971] AC 610
This summary examines the British Oxygen Co Ltd v Minister of Technology [1971] case, pivotal for understanding judicial review limits on executive powers in administrative law, vital for law students.
Facts
British Oxygen invested about £4 million in gas cylinders used in its business, each costing approximately £20. A statutory industrial grant scheme gave the minister discretion to support qualifying investment. The department adopted a policy against grants for items costing less than £25. The company argued that applying that threshold to its cylinders failed to recognise the scale and character of its expenditure. It challenged the refusal, raising the question whether a general administrative policy improperly restricted the discretion Parliament had conferred on the minister.
Legal Issue
Were the single gas cylinders eligible for grants? Did the £25 policy implemented by the Minister come within their discretionary powers awarded by the Act?
Held
The House of Lords dismissed the appeal. The minister could adopt a general policy setting a minimum item value when administering the discretionary grant scheme. A public authority dealing with numerous similar applications is entitled to pursue consistency and administrative efficiency. It must, however, remain willing to consider an applicant with a relevant reason for departing from the policy or changing it. On the facts, British Oxygen’s case had been considered, and the minister was not obliged to accept it. The decision distinguished lawful use of policy from an unlawful refusal to exercise discretion. It did not eliminate review for bad faith, irrationality or other errors in exercising the statutory power.
⭐ Legal Principle
A public authority may adopt a general policy to guide a statutory discretion, but must remain willing to consider a relevant case for an exception or change. Listening to such a case does not oblige the authority to accept it.
Significance
British Oxygen reconciles consistency in large-scale administration with the prohibition on fettering discretion. A policy may be detailed and firm without becoming unlawful, provided the authority remains open to a genuinely different case. The principle is especially useful for grants, benefits and licensing decisions made in high volumes. An applicant is entitled to consideration, not an exception merely because one is requested. The case should not be described as giving ministers unlimited discretion immune from ordinary public-law constraints.
Common exam questions about this case
Why was a minimum-value policy permissible?
The minister administered a large grant scheme and could adopt a general rule to manage recurring applications consistently. Nothing required a fresh policy debate for every individual item. The essential safeguard was continued willingness to consider a case that justified departing from, or reconsidering, the general approach.
Why did the company’s large aggregate expenditure not decide the claim?
The policy assessed the value of individual items, not merely total expenditure. Although the company spent millions on cylinders, each cost less than the threshold. Its argument could be considered without obliging the minister to approve it. A duty to listen does not create a duty to make the requested grant.
What would unlawful fettering look like?
It would occur if the authority refused to entertain a relevant request for an exception solely because its policy admitted none. British Oxygen permits a strong policy but requires an open mind to something new. The review question is whether discretion was genuinely exercised, not whether the applicant persuaded the authority.
