What is judicial review?
Answer
Judicial review is a legal principle that means the courts have the power to check whether laws or actions taken by the government follow the constitution. If the court reviews a law or action and finds that it does not follow the constitution, it can strike it down. Black's Law Dictionary's defines judicial review formally as:
judicial review (1851) 1. A court's power to review the actions of other branches or levels of government; esp., the courts' power to invalidate legislative and executive actions as being unconstitutional. 2. The constitutional doctrine providing for this power. 3. A court's review of a lower court's or an administrative body's factual or legal findings.
