Justice Samuel Alito Marks 20 Years on the Supreme Court with Landmark Rulings and Originalist Approach

What's happening

Supreme Court Justice Samuel Alito recently celebrated his 20th anniversary on the nation's highest court, marking two decades of influential judicial service. Appointed by President George W. Bush in 2006, Alito has become known for his steadfast commitment to originalism, a judicial philosophy that interprets the Constitution based on its original meaning at the time it was enacted. Over the years, he has authored several landmark decisions that have significantly impacted American law and society, including the pivotal 2022 ruling in Dobbs v. Jackson Women’s Health Organization, which overturned Roe v. Wade.

Alito's tenure on the Supreme Court has been marked by a focus on interpreting the Constitution strictly according to its text, often resisting contemporary societal trends or evolving norms. This approach has placed him at the center of heated debates about the role of the judiciary in shaping policy and rights. His originalist perspective emphasizes that judges should apply the law as written, rather than making decisions based on personal or popular views. This judicial philosophy has influenced his opinions on a range of contentious issues, from abortion rights to free speech and parental rights.

One of the most consequential moments of Alito’s career came with the Dobbs decision, which reversed nearly 50 years of precedent by ending the federal constitutional right to abortion established under Roe v. Wade. In the majority opinion, Alito argued that the Constitution does not explicitly mention abortion, and therefore, the issue should be returned to the states to regulate. This ruling has sparked widespread national debate, with supporters praising it as a restoration of states' rights and critics warning it undermines women's autonomy and access to reproductive healthcare.

Beyond abortion, Alito has been a vocal defender of free speech, often cautioning against government overreach and censorship. In a recent dissent in Murthy v. Missouri, he criticized a ruling that allowed government collaboration with technology companies to moderate content, calling it "blatantly unconstitutional." He underscored the importance of protecting free speech as a cornerstone of democracy and warned that such decisions could pave the way for further government restrictions on expression. This stance aligns with his broader judicial philosophy that prioritizes safeguarding individual liberties against government intrusion.

What's at stake

Parental rights have also been a significant focus of Alito’s opinions. In Mahmoud v. Taylor, he authored the majority opinion affirming that parents have the right to direct their children’s religious upbringing and to opt them out of educational content conflicting with their beliefs. Alito argued that mandating exposure to certain materials, such as LGBTQ+-inclusive storybooks, imposes an unconstitutional burden on parents' religious freedoms. This ruling highlights his commitment to protecting religious liberty, which he has described as fragile and historically subject to persecution.

Alito’s views on equality and affirmative action further illustrate his originalist approach. He has described the Constitution as a "colorblind" document and has expressed opposition to policies that favor specific racial groups, emphasizing the importance of treating all individuals as equals under the law. These positions have sparked debate about how best to achieve racial justice and equality in modern America. At the same time, Alito has warned about the fragility of religious liberty, urging vigilance against intolerance and persecution that have recurred throughout history.

Despite his serious judicial demeanor, Alito has occasionally shown a lighter side, displaying humor and personal reflection in public appearances. He has spoken about his background as the son of Italian immigrants who valued hard work and education, shaping his views on perseverance and opportunity. This personal history informs his judicial philosophy and public persona, blending intellectual rigor with a grounded sense of determination. As he marks two decades on the Supreme Court, Alito’s legacy continues to provoke robust discussion across the political spectrum.

The core tension surrounding Alito’s tenure revolves around the balance between adhering to constitutional text and adapting to evolving societal values. Supporters argue that his originalist approach restores constitutional integrity and limits judicial activism, while critics contend it risks undermining established rights and protections. His rulings on abortion, free speech, and parental rights have had profound implications for millions of Americans, influencing ongoing legal and political battles. These issues remain deeply divisive and central to the nation’s broader debates about law, liberty, and governance.

Looking ahead, Justice Alito is expected to remain a key voice on the Supreme Court as it confronts future cases involving constitutional interpretation and individual rights. Observers will be watching closely how his originalist philosophy shapes decisions on emerging issues such as digital speech, religious freedoms, and state-level regulations. With his 20-year milestone, the court continues to navigate complex legal terrain, and Alito’s influence will likely persist as a defining element of its jurisprudence in the years to come.
