 Actions taken under the royal prerogative were traditionally thought to be nonjusticiable political matters and thus not subject to judicial review, but "Council of Civil Service Unions v Minister for the Civil Service" [1984] UKHL 9 established that they can be, depending on the purpose for which the prerogative powers are exercised.Sometimes the legislator may want to exclude the powers of the court to review administrative decision, making them final, binding and not appealable ("R (Cowl) v Plymouth City Council").However, the courts have consistently held that none but the clearest words can exclude judicial review.
