One interpretation of royal reserve powers treats them as an emergency safeguard constrained by the consequences of using them. Casual intervention by a monarch would be politically unacceptable. In a hypothetical authoritarian crisis, a sovereign who used those powers to stop a dictatorship could initially receive public support. Parliament would then be expected to remove the powers to prevent another intervention. Their value in this argument depends partly on their availability for a crisis, even though exercising them could end that availability.
