Secretary of State for Education v Tameside BC [1977]

Labour
LEA planned to introduce comprehensive schooling.
Conservatives
won local elections and reversed plans so as to retain 3 grammar schools.
Secretary
of State exercised power under Education Act 1944 to direct authority to carry
out original plan.
Act
gave him power, if he felt authority was acting unreasonably, to give such directions
as appeared to him expedient.
House
of Lords held that ‘unreasonably’ here did not simply mean disagreeing on a
matter of policy, nor could it include disruption that might ensure from change
in education policy.
