The Court is formally a judicial body created by Article III: nine justices apply the Constitution. The case that it is political is that its membership is fought over by presidents and the Senate, and its biggest rulings track the appointing party. The same Constitution produced Roe (1973) and Dobbs (2022) - what changed was the majority.
Nine justices: Chief Justice Roberts plus eight associates, appointed for life and confirmed by simple Senate majority since the 2017 nuclear option. Since Barrett's confirmation in 2020 there has been a 6-3 conservative majority (Thomas, Alito, Roberts, Gorsuch, Kavanaugh, Barrett) against three liberals (Sotomayor, Kagan, Jackson, the first black woman justice, 2022).
The politics is clearest in the appointments battle. In 2016 the Senate refused to consider Merrick Garland; in 2020 it confirmed Barrett a week before an election. That asymmetry, not any change in the law, built the majority that then delivered Dobbs, Bruen and SFFA.
Two rival approaches explain why justices split. Originalism reads the Constitution for its original public meaning (associated with Scalia and the current conservatives); the living constitution reads it as adapting to modern conditions (the Warren Court). Originalism tends to return contested questions to elected bodies (Dobbs sent abortion back to the states); the living approach tends to expand implied rights (Roe, Obergefell).
The case that the Court protects rights rests on the Warren and Burger era and some recent wins:
The case that rights have been rolled back rests on the post-2013 record:
Activist charge: the Roberts Court has overturned major precedents (Roe, Chevron, VRA sections) and shaped policy on abortion, guns and elections. Trump v Anderson (2024) even decided who could appear on primary ballots. Restraint reply: the Court cannot enforce its own rulings, often returns questions to elected branches, and originalists argue this is judicial humility, not power-grabbing.
Reform proposals follow the "too powerful" view: court-packing (expanding the bench), 18-year staggered terms to end lifetime tenure, and ethics reform after the Thomas and Alito disclosure controversies.
