Constitutional review in Germany
The constitution of the Federal Republic of Germany establishes a separate Federal Constitutional Court of Germany that is empowered with reviewing acts of the legislature for their constitutionality.
Most states also have separate courts for the according purpose. These are separate Supreme Courts that do not deal with appellate cases in civil and criminal law - but rather, just in constitutional cases.
The Federal Constitutional Court of Germany can even review and reject constitutional amendments on the grounds that they are contradictory to the rest of the Federal Republic Constitution. This goes beyond even the powers of the Supreme Court of the United States, and the Supreme Court of Canada.
