Judicial review is a legal doctrine that empowers courts to review and declare actions of the legislature or executive as unconstitutional. There are two general judicial review systems:

(1) Decentralized judicial review systems empower any court to declare a law or policy unconstitutional. In such systems, plaintiffs bring a claim against a law or policy that the court may strike down. 

(2) Centralized judicial review systems empower one specific court — typically a Constitutional Court — to declare a law or policy unconstitutional. Here, a claim begins at the trial level and must work its way up through the court system through appeals to reach the Constitutional Court.
