๐ What is Judicial Review?
Judicial review is the power of the judiciary, particularly the Supreme Court, to examine the actions of the legislative, executive, and administrative branches of government and to determine whether such actions are consistent with the Constitution. If a law or action is deemed unconstitutional, it is nullified. It's a cornerstone of checks and balances, ensuring no single branch becomes too powerful.
๐ History and Background
While not explicitly mentioned in the Constitution, the power of judicial review was established in the landmark case of Marbury v. Madison (1803). Chief Justice John Marshall asserted the Court's authority to declare laws unconstitutional, solidifying the judiciary's role as a co-equal branch of government.
๐ Key Principles of Judicial Review
- โ๏ธ Constitutional Supremacy: The Constitution is the supreme law of the land, and all actions must conform to it.
- ๐ Judicial Independence: The judiciary must be independent from political pressure to impartially interpret the Constitution.
- ๐ข Standing: Parties bringing a case must have a legitimate stake in the outcome (i.e., they must have suffered a direct injury).
- ๐๏ธ Separation of Powers: Judicial review reinforces the separation of powers by limiting the authority of the other branches.
๐ Real-World Examples of Judicial Review
- ๐ซ Brown v. Board of Education (1954): Declared state-sponsored segregation in public schools unconstitutional, overturning the "separate but equal" doctrine established in Plessy v. Ferguson (1896).
- โ๏ธ Roe v. Wade (1973): Established a woman's constitutional right to an abortion, based on the right to privacy. (Note: this decision was later overturned by Dobbs v. Jackson Women's Health Organization (2022).)
- ๐ณ๏ธโ๐ Obergefell v. Hodges (2015): Legalized same-sex marriage nationwide, based on the Equal Protection Clause of the Fourteenth Amendment.
- ๐งโโ๏ธ National Federation of Independent Business v. Sebelius (2012): Upheld most of the Affordable Care Act (ACA), but limited the federal government's power to mandate Medicaid expansion.
