# US Supreme Court 2026-27 term docket > Live situation record from CLSTR: https://clstr.news/situations/us-supreme-court-2026-27-term-docket > Updated: 2026-10-19T15:00:42.000Z. Sources: 33. Developments: 3. The U.S. Supreme Court has commenced its 2026–27 term with a docket featuring several high-stakes legal challenges. A central focus involves climate change litigation, specifically the case of Suncor Energy Inc. and ExxonMobil against Boulder County, Colorado. Local officials are seeking financial compensation for climate-related damages, while the energy companies contend that federal laws, such as the Clean Air Act, preempt state-level tort claims. The Trump administration has signaled support for the energy companies, describing the lawsuits as attempts to regulate emissions through the judiciary. Religious liberty remains a prominent issue with St. Mary Catholic Parish v. Roy. This Colorado dispute examines whether Catholic preschools can participate in a state universal preschool program if they must adhere to nondiscrimination rules regarding sexual orientation and gender identity, which the schools argue conflicts with their religious teachings. Immigration policy is also under intense scrutiny. The Court is reviewing the legality of a Trump administration policy that mandates the detention of certain undocumented immigrants during deportation proceedings, a move that departs from previous federal interpretations allowing release on bond. Other immigration matters concern the administration’s ability to deport individuals to countries with which they have no ties. Additionally, the Court is examining civil rights enforcement, specifically whether employees at federally funded universities have a private right of action to sue for workplace sex discrimination under Title IX. The Trump administration argues such rights must be explicitly authorized by Congress. Other significant matters include challenges to state-level bans on semi-automatic rifles, voter citizenship requirements, and executive power boundaries. ## Claims - ExxonMobil and Suncor Energy are appealing a Colorado court ruling regarding a lawsuit by Boulder officials.
