The justices have scheduled major disputes over state rifle bans, immigration detention and climate lawsuits, while leaving room to add more cases to an unusually light docket.
The Supreme Court’s early 2026–27 docket puts three contentious legal questions before the justices: how far states may restrict semiautomatic rifles, what process immigrants are owed before detention or removal, and whether federal law displaces state climate-liability lawsuits. The Court has agreed to hear about 30 cases so far—roughly half the usual number for a term—leaving space for additional disputes, according to recent coverage of the docket.
The cases are scheduled for argument, not decided. Their practical reach will depend on the questions the justices resolve and the reasoning they adopt, rather than on the prominence of the disputes alone.
On December 2, the Court is set to hear consolidated challenges from Illinois and Connecticut to state and local restrictions on possessing, selling or transferring semiautomatic rifles. The cases raise questions under the Second and Fourteenth Amendments about the authority of governments to restrict firearms. Legal experts cited in reporting have described them as the most consequential Second Amendment cases since *District of Columbia v. Heller* in 2008, which recognized an individual right to possess a firearm for lawful purposes such as self-defense in the home.
That comparison signals the stakes, not the outcome. The Court’s eventual analysis will determine how the challenged laws fit within the constitutional framework and what limits, if any, apply to government regulation of these weapons. Until the justices issue a ruling, the cases do not invalidate or uphold the bans.
Immigration disputes will test the government’s power to detain people without bond hearings and to remove people to countries other than their own. One case asks whether the administration may detain millions of immigrants without providing bond hearings. Another, set for argument December 9, concerns whether people facing removal to a third country may challenge the risk of persecution or torture there.
The Court’s order on the third-country policy allows the government to identify “other” issues for briefing, an unusual step that could broaden the questions considered. The central practical issue is whether the government may carry out removals without giving affected people an opportunity to contest the asserted danger. The Court has not yet answered that question.
Climate liability is on the calendar October 5, when the justices are scheduled to hear *Suncor Energy Inc. v. County Commissioners of Boulder County*. The case tests whether federal law bars Colorado’s state-court lawsuit seeking to hold fossil-fuel companies liable for harms connected to climate change. Similar suits have been filed around the country, with billions of dollars potentially at stake.
The dispute asks how federal law interacts with state-law claims; it is not a general ruling on climate policy or a finding of liability against the companies. Justice Samuel Alito recused himself, according to the Court’s announcement, which did not state a reason.
The Court added three cases to its term on October 1, including the immigration detention dispute, a religious-zoning case and a case involving protections for former spouses of U.S. servicemembers. Separately, an administration request concerning federal prison healthcare and accommodations for transgender inmates has been placed on the emergency docket. Challengers must respond by 4 p.m. EDT October 8; the material provided does not describe a merits ruling in that matter.
With the docket still comparatively small, additional cases involving the administration, elections, gun rights or constitutional questions may yet be added. For now, the scheduled arguments show the Court taking up disputes about the division of authority between federal and state governments, and about the constitutional protections that constrain government power. The decisions—not the docket announcements—will establish what those boundaries mean in practice.
