Origins of Judicial Review
Judicial review, a cornerstone of U.S. constitutional law, has its roots in the Constitution itself. Article III grants judges power to rule on cases, while Article VI establishes the Constitution as supreme law. The Framers' oaths further obligate them to protect the Constitution from overreach.
Alexander Hamilton, in The Federalist No. 78, advocated for courts to act as guardians of the Constitution, rejecting laws that violated its boundaries. He portrayed courts as protectors of individual rights against legislative excesses.
Marbury v. Madison solidified judicial review in American jurisprudence. Chief Justice John Marshall declared that laws conflicting with the Constitution were invalid, establishing the court's authority to strike down unconstitutional legislation.
While Marbury v. Madison is often credited, the concept of judicial review predates it. State courts had already invalidated laws conflicting with state constitutions, indicating judicial review emerged from constitutional necessity rather than legislative grant.
Judicial Review in Practice
The Supreme Court wields judicial review to ensure government actions remain within constitutional limits. Landmark cases demonstrate its potency in shaping American law and society.
Brown v. Board of Education exemplifies judicial review's impact, with the Court striking down segregation as unconstitutional. Similarly, Roe v. Wade saw the Court defend privacy rights against state restrictions on abortion.
Critics argue that such rulings, including Obergefell v. Hodges legalizing same-sex marriage, represent judicial overreach. They contend that courts overstep their bounds, encroaching on legislative territory and bypassing democratic processes.
Nonetheless, judicial review continues to serve as a check on government power, upholding constitutional rights and striking down overreaching actions.

Global Perspectives on Judicial Review
Judicial review varies globally. European countries like Germany, Italy, and Spain employ specialized constitutional courts that review laws after enactment. France's Conseil Constitutionnel conducts pre-emptive reviews before laws take effect.
India's Supreme Court actively uses judicial review to protect human rights and preserve the constitution's "basic structure." Latin American countries have adopted similar practices, with the Inter-American Court of Human Rights safeguarding individual rights across multiple nations.
While methods differ, the underlying principle remains: keeping lawmakers in check and protecting constitutional integrity. Global judicial review stands as a bulwark against unchecked power, despite critiques of its scope and implementation.
Judicial Review and Minority Rights
Judicial review serves as a crucial defender of minority rights against majority tyranny. It ensures that constitutional protections supersede transient majority will.
Brown v. Board of Education exemplifies this role, with the Court striking down racial segregation despite widespread support for "separate but equal" policies. Obergefell v. Hodges similarly protected same-sex marriage rights against majority opposition.
Critics argue that such rulings represent judicial overreach. However, this view often overlooks judicial review's essential function in upholding constitutional principles and protecting minority rights from majority bias.
Ultimately, judicial review safeguards the Constitution's promise of equal protection, ensuring every citizen stands equal before the law regardless of majority sentiment.

Contemporary Challenges and Criticisms
Critics of judicial review argue it represents judicial overreach, with unelected judges usurping legislative and executive roles. They contend this disrupts the constitutional balance of power, allowing courts to craft policy rather than interpret law.
Cases like Roe v. Wade and Obergefell v. Hodges are cited as examples of judicial activism overriding democratic processes. Conservative voices advocate for judicial restraint, arguing courts should defer to elected branches.
Defenders counter that judicial review provides necessary checks on other branches, especially when partisanship or political pressures impede lawmaking. They argue judges' primary duty is to the Constitution, not prevailing politics.
The ongoing debate reflects tensions inherent in maintaining democratic order and liberty. It underscores the judiciary's contentious role in governance, a struggle as old as the Constitution itself.

Judicial review remains a key mechanism in constitutional governance, serving as a check on power and protector of rights against unchecked authority.
