In politics and law, liberal legalism is a belief that politics should be constrained by legal constitutional boundaries.[1] Liberal legalism has also been called legal constitutionalism, such as is found in United States and Germany, with political constitutionalism, which is more typical of Britain, by British constitutional scholar Adam Tomkins. He argues in his book Our Republican Constitution that the British system of governance, in which Parliament controls government ministers, provides a better check on executive power than a system like that of the United States, where courts and laws are used to check executive power.[2]
