U.S. Supreme Court decisions issued in January 2026. Credit: Kibble Facts
January 2026 did not deliver a single headline-grabbing culture-war ruling. Instead, the Supreme Court issued a series of quieter decisions that collectively shape how power moves through the legal system. These cases dealt with access to courts, limits on punishment, election oversight, police authority in emergencies, and the finality of judgments.
None of them rewrite constitutional doctrine. All of them determine who gets heard, who gets shut out, and how much leverage institutions retain over individuals. Taken together, January’s rulings reveal a Court focused less on ideology and more on procedural control, drawing clearer boundaries around who can challenge the system and when.
1) Berk v. Choy (No. 24-440) – Jan. 20, 2026
Decision:
The Supreme Court unanimously held that federal courts do not apply state affidavit-of-merit requirements for medical malpractice claims filed in federal court.
Opinion:
The Court reaffirmed that federal procedural rules govern cases in federal court. Because state affidavit-of-merit laws conflict with Federal Rule of Civil Procedure 8, they cannot be enforced in federal malpractice actions.
Vote Breakdown:
Unanimous decision (9–0)
Who voted yes:
All Justices (9–0)
What it means for the public:
Patients bringing malpractice claims in federal court are no longer blocked by state-level paperwork requirements that can prevent cases from being heard on their merits.
Who benefits:
Medical malpractice plaintiffs and attorneys filing in federal court.
Who gets harmed:
Medical providers and insurers who relied on affidavit requirements to dismiss claims early.
Who stays central:
Federal courts and litigants navigating the boundary between state and federal procedure.

2) Ellingburg v. United States (No. 24-482) – Jan. 20, 2026
Decision:
The Supreme Court held that criminal restitution under the Mandatory Victims Restitution Act counts as punishment for purposes of the Ex Post Facto Clause and cannot be applied retroactively.
Opinion:
The Court reasoned that restitution is imposed as part of a criminal sentence, enforced by the government, and carries punitive consequences. As a result, increasing restitution obligations for past conduct violates constitutional protections against retroactive punishment.
Vote Breakdown:
Unanimous decision (9–0)
Who voted yes:
All Justices (9–0)
What it means for the public:
Defendants cannot be subjected to harsher financial penalties based on laws enacted after their conduct occurred.
Who benefits:
Criminal defendants facing restitution tied to older offenses.
Who gets harmed:
Government efforts to retroactively expand restitution orders, and victims seeking compensation through those mechanisms.

What January 2026 Actually Changed
Across eight decisions, the Court recalibrated the balance between access and finality. In criminal cases, the Court pushed back against sentence stacking and retroactive punishment, limiting how aggressively the government can multiply penalties after the fact.
At the same time, it reinforced strict limits on post-conviction review, signaling that once a conviction survives state review, federal courts will rarely intervene. In civil litigation, the Court strengthened uniform federal procedures, making it harder for states to block lawsuits through technical gatekeeping rules.
On elections, the Court lowered the threshold for candidates to challenge how votes are counted, opening the door to more litigation over election administration. In policing, the Court reaffirmed broad authority for emergency home entry when lives may be at risk.
The winners this month were procedural clarity, institutional stability, and selective access to judicial review. The losers were litigants relying on delay, retroactive penalties, or procedural traps to avoid scrutiny. For the public, the larger takeaway is structural.
January 2026 was about who controls the rules of engagement. The Court clarified when the system must open its doors and when it will close ranks. That balance, more than any single outcome, defines the real impact of this month’s decisions.
