The U.S. Supreme Court opens its October 2026 term on Monday with a docket that is already drawing outsized attention from litigators, regulators, and in-house legal teams. The justices are expected to hear major disputes touching immigration detention, firearm restrictions, climate-liability claims, voting rules, and LGBT-rights issues—areas where even incremental doctrinal shifts can quickly reshape litigation strategy nationwide.

Although no merits rulings have been issued yet, the composition of the Court’s calendar is itself a major legal development.
