“The United Kingdom and its dependent territories within Her Majesty’s dominions form one realm having one undivided Crown. This general principle is not inconsistent with the further principle that on the grant of a representative legislature, and perhaps even as from the setting up of courts, a legislative council and other such structures of government, Her Majesty’s government in a colony is to be regarded as distinct from Her Majesty’s government in the United Kingdom. To the extent that a dependency has responsible government, the Crown’s representative in the dependency acts on the advice of local ministers responsible to the local legislature, but in respect of any British overseas territory or other dependency of the United Kingdom, acts of Her Majesty herself are performed only on the advice of the United Kingdom government.”
