At Her Majesty's pleasure (sometimes abbreviated to Queen's pleasure or, when appropriate, at His Majesty's pleasure or King's pleasure) is a legal term of art referring to the indeterminate length of service of certain appointed officials or the indeterminate sentences of some prisoners. It is based on the concept that all legitimate authority for government comes from the Crown. Originating in the United Kingdom, it is now used throughout the Commonwealth realms. In realms where the monarch is represented by a Governor-General, the phrase may be modified to be at the Governor's pleasure, since the governor-general, governor, or lieutenant governor is the Queen's personal representative in the country, state or province.
