How Judicial Review Shapes Constitutional Interpretation
Quick fact
The U.S. Supreme Court established judicial review in 1803 with Marbury v. Madison, though the Constitution never explicitly grants this power to the courts.
Why this is interesting
Imagine a law that perfectly fits the will of the majority, yet is struck down forever by a handful of unelected judges. How do they get such power, and what does it mean for the constitution?

Understanding How Judicial Review Shapes Constitutional Interpretation
Think of the constitution as the rulebook for a game. But who refs the game when rules seem unclear or violated? In many democracies, a court does. Judicial review is that power: courts can look at a law or act of government and declare it 'unconstitutional,' meaning it goes against the rulebook. This doesn't happen during the law's creation; it happens when someone challenges it in court. The court doesn't rewrite the rulebook, but it decides what the rule means and whether the action follows it. If it doesn't, the action is nullified. This makes the court the final umpire, shaping how the rulebook is applied in real life.
A deeper explanation
The mechanism of judicial review works through a 'checking' process: a case must come to court, usually after a conflict over a law's application. The court examines the constitutional text, intent, prior interpretations (precedent), and modern circumstances. When it rules, it sets a precedent—binding for lower courts and persuasive for itself. This is how constitutional meaning evolves: not by amending the words, but by interpreting them. For example, the U.S. Supreme Court's interpretation of 'equal protection' changed segregation from constitutional to unconstitutional. Because the court's interpretations are authoritative, they shape public policy, protect rights, and sometimes spark backlash. Thus, judicial review is a powerful engine for constitutional change, but it also raises debates about judicial power and legitimacy.
