Constitutional Courts

Further information: Constitutional court and Constitutionality

Constitutions are often, but by no means always, protected by a legal body whose job it is to interpret those constitutions and, where applicable, declare void executive and legislative acts which infringe the constitution. In some countries, such as Germany, this function is carried out by a dedicated constitutional court which performs this (and only this) function. In other countries, such as Ireland, the ordinary courts may perform this function in addition to their other responsibilities. While elsewhere, like in the United Kingdom, the concept of declaring an act to be unconstitutional does not exist.

A constitutional violation is an action or legislative act that is judged by a constitutional court to be contrary to the constitution, that is, unconstitutional. An example of constitutional violation by the executive could be a public office holder who acts outside the powers granted to that office by a constitution. An example of constitutional violation by the legislature is an attempt to pass a law that would contradict the constitution, without first going through the proper constitutional amendment process.

Some countries, mainly those with uncodified constitutions, have no such courts at all. For example the United Kingdom has traditionally operated under the principle of parliamentary sovereignty under which the laws passed by United Kingdom Parliament could not be questioned by the courts.
