In Finland, the constitutionality of laws is examined in advance. This mainly takes place in Parliament, and especially in its Constitutional Law Committee. The goal of this parliamentary control is to prevent in advance that laws which are in conflict with the Constitution are enacted in the ordinary legislative procedure.

No constitutional court exists in Finland, but the courts and other authorities are under an obligation to interpret legislation in such a way as to adhere to the Constitution and to respect human rights. According to the Constitution, the courts should give preference to the Constitution when they decide a case if the application of an act would be in manifest conflict with the Constitution.
