Air traffic – Civil Aviation Authority. The Administrative Court held that it was the Secretary of State for Transport (SST) and the Civil Aviation Authority (CAA), rather than the Secretary of State for Defence and the Ministry of Defence (MOD), which had statutory responsibility for safety in relation to the use of a RAF airport by civil aircraft. Those responsibilities could not be delegated to the MOD or Military Aviation Authority (MAA). However, the SST and CAA could rely upon information and assessments provided by the MAA and MOD to fulfil their statutory functions. A declaration that the CAA had power to impose conditions on the notification of government aerodromes in relation to matters concerning the safety of the use by civil aircraft of such aerodromes would not be made because it was uncontentious.
