Anthony Kennedy — Associate Justice and pivotal swing vote on the U.S. Supreme Court

Early career and appointment

Before joining the high court, Kennedy had a long legal career that included private practice and service on the federal bench. He was nominated to the Supreme Court by the President and confirmed by the Senate in the late 1980s. His elevation to the Court followed the vacancy created by Justice Lewis F. Powell Jr.'s retirement, and his confirmation placed him among the Court's longest-serving members.

Judicial approach and role

Kennedy was regarded as a conservative on many issues but also as a strong defender of individual liberties and dignity in several landmark cases. After the retirement of Justice Sandra Day O'Connor in 2006, he more frequently became the decisive vote in narrow decisions and thus functioned as a swing figure on matters of constitutional law. He assumed seniority among the associate justices following the death of Justice Antonin Scalia in 2016. Commentators and litigants often emphasized his willingness to consider precedent, federalism, and the human impact of rulings when writing opinions.

Notable opinions and legal impact

Kennedy authored opinions in several cases that reshaped American law on civil rights, criminal procedure, detainee rights, and campaign finance. Among the most influential majority rulings he wrote or joined are:

• Lawrence v. Texas — invalidated laws criminalizing consensual same-sex intimate conduct, a key step toward later marriage-equality decisions.
• Obergefell v. Hodges — joined the majority that recognized a constitutional right to same-sex marriage nationwide.
• Boumediene v. Bush — affirmed that certain detainees held at Guantanamo Bay have habeas corpus rights to challenge detention in federal court.
• Citizens United v. FEC — a major ruling on political speech and corporate spending in elections, which reshaped campaign-finance law.

These decisions illustrate the range of topics on which Kennedy's vote and authorship had a decisive effect: privacy and liberty, separation of powers, and the balance between democratic processes and free-speech protections.

Retirement and legacy

On June 27, 2018, Kennedy announced his retirement from the Court, effective July 31 of that year. His departure set off a consequential nomination process and a replacement who would affect the Court's ideological balance. Observers of modern constitutional law view Kennedy as a pivotal figure whose opinions and votes played a central role in several of the Court's defining rulings on civil liberties and the structure of government.

Further reading and context
