Court Grants Three Cases as New Term Is Set to Begin — Supreme Court

• Holding: The Supreme Court granted three cases for its October Term 2026, expanding the docket as arguments commence in the coming weeks.
• Vote / posture: Grants as new term begins; 30 cases now on the oral argument docket with 0 arguments yet held.
• Why it matters: The three newly granted cases span climate liability, immigration enforcement, and retirement fund investment policy—core issues for the Trump administration and a court increasingly focused on limiting plaintiff standing and environmental regulation.

Suncor Energy Inc. v. County Commissioners of Boulder County — Supreme Court

• Holding: The Court granted review to determine whether a climate liability suit may proceed against energy companies seeking damages for climate change injuries.
• Vote / posture: Cert granted; oral arguments scheduled for October 5, 2026 at 9:30 AM ET.
• Why it matters: This case will clarify the contours of standing and justiciability in climate litigation, potentially affecting thousands of state and local climate suits against fossil fuel producers. Justice Alito recused himself, signaling sensitivity to political pressures.

Johnson v. United States Congress — Supreme Court

• Holding: The Court accepted an immigration case challenging the Trump administration's deportation of immigrants to third-party countries (so-called "third-country deportations").
• Vote / posture: Cert granted; oral arguments scheduled for October 5, 2026 at 11:00 AM ET.
• Why it matters: The ruling will resolve whether the administration can circumvent U.S. asylum obligations by deporting migrants to countries other than their origin nation. A SCOTUS ruling lets Trump resume violating human rights, according to immigration advocates, though the Court has not yet ruled on the legality of the practice itself.

Anderson v. Intel Corporation Investment Policy Committee — Supreme Court

• Holding: The Court agreed to hear arguments on retirement fund investment choices and fiduciary obligations under ERISA.
• Vote / posture: Cert granted; oral arguments scheduled for October 6, 2026 at 10:00 AM ET.
• Why it matters: This pension-law case will clarify investment discretion for corporate retirement plans, affecting millions of plan participants and corporate governance practices.

Tech Antitrust & Regulatory Battles

Google LLC vs. U.S. Department of Justice — U.S. District Court (Eastern District of Virginia)

• What happened this week: The DOJ again won substantial relief against Google in its advertising technology (ad tech) monopolization case, with the court ordering significant behavioral remedies.
• Stakes: The ruling reinforces the government's two antitrust victories against Google, setting up potential appeals and broader remedies affecting Google's $175 billion ad empire.
• Status: The decision clears the path toward structural or behavioral enforcement; Google is expected to appeal. Tech industry observers note that remedies—not verdicts alone—will determine whether Big Tech's market dominance can be checked.

FTC v. OpenAI, Anthropic, and other AI Giants — Federal Trade Commission

• What happened this week: The FTC opened a broad probe into AI giants including OpenAI and Anthropic as part of intensified antitrust scrutiny of artificial intelligence sector concentration.
• Stakes: The investigation targets whether AI foundation-model makers and large language model providers are engaging in anticompetitive conduct or exclusive dealing that locks out competitors.
• Status: Ongoing investigation; both FTC and DOJ have designated AI as an antitrust enforcement priority under a joint statement with EU and UK authorities.

Apple and Amazon — UK Competition Tribunal

• What happened this week: A UK tribunal allowed part of a renewed antitrust lawsuit against Apple and Amazon to proceed, advancing claims of anti-competitive app store and platform practices.
• Stakes: The case seeks to establish that both companies abused market dominance in mobile commerce and e-commerce respectively.
• Status: Litigation ongoing; the tribunal's decision allows the suit to move forward on key counts, suggesting jurisdictional and substantive vulnerabilities for both firms in the UK.

Other Notable Rulings & Enforcement

• Sixth Circuit Blocks Hundreds of Late-Filed PBM Opioid Suits: In a major MDL decision issued just 18 hours ago, the U.S. Court of Appeals for the Sixth Circuit found that the trial judge presiding over the multidistrict opioid litigation improperly allowed hundreds of plaintiffs to file additional claims against pharmacy benefit managers well after the filing deadline. The ruling reverses a lower-court order and may eliminate or significantly delay hundreds of opioid cases, establishing important procedural guardrails in mass tort litigation.

• Antitrust Press Round-Up (October 1, 2026): Multiple enforcement fronts active simultaneously: Microsoft gaming chief states "Xbox is not for sale" amid antitrust inquiries; California Governor Newsom signs COMPETE Act targeting gatekeeper platforms; Paramount settlement with states approved by federal judge; Google seeks interim suspension of EU decisions on search interoperability under the DMA.

Case of the Week — Deep Dive

Suncor Energy Inc. v. County Commissioners of Boulder County (Climate Liability / Standing)

Background: Boulder County, Colorado, and other jurisdictions have pursued climate litigation against fossil fuel producers, seeking damages for climate-related harms and adaptation costs. Energy companies challenged the suits on multiple grounds, including lack of standing and political question doctrine. After surviving motions to dismiss, Suncor and co-defendants sought Supreme Court review to prevent a wave of similar climate litigation nationwide.

What the Court Said: The Supreme Court granted certiorari, indicating at least four justices believe the case presents an important question worthy of plenary review. Justice Alito's recusal—unusual for a sitting justice mid-term—signals potential ideological fracture and suggests the Court is navigating carefully between pro-business and pro-environmental constituencies. The grant itself signals skepticism toward climate suits: the Court rarely intervenes in what many see as quintessentially local tort claims unless fundamental questions of federal jurisdiction or constitutional standing doctrine are implicated.

Ripple Effects: A decision restricting standing in climate cases could foreclose thousands of pending suits in state and federal courts, fundamentally reshaping climate liability law. Conversely, a decision allowing suits to proceed would embolden plaintiffs' attorneys nationwide and create massive discovery burdens on energy companies. The case also touches on the separation of powers—whether courts can fashion climate remedies or whether such matters are reserved to legislatures. Environmental groups, fossil fuel companies, and the Biden administration (now Trump administration in oral arguments) have all filed amicus briefs, making this a flashpoint case for the 2026 term.

Reader Takeaways

• If you run a business: Watch the Google antitrust outcomes closely—the DOJ's ad tech victory signals aggressive enforcement of monopolization theories, and your platform or marketplace practices may face FTC/DOJ scrutiny if you're dominant in your sector. Climate liability cases may also expand your environmental tort exposure if you operate in fossil fuels or energy-intensive industries.

• If you build tech products: The FTC's AI probe and UK antitrust actions against Apple and Amazon indicate regulators worldwide are targeting app store gatekeeping, exclusive dealing, and AI market concentration. Ensure your data practices, third-party access policies, and model licensing comply with emerging antitrust and interoperability standards, particularly under the EU's DMA.

• If you're a consumer or investor: Climate litigation outcomes will shape energy company valuations and litigation reserves; the immigration ruling will affect asylum law and border enforcement; and antitrust victories against Google suggest lower search costs and more competition ahead—but appeals could take years to resolve.
