Lead Story
Supreme Court Narrows Federal Firearms Ban for Unlawful Drug Users
What happened: The U.S. Supreme Court narrowed 18 U.S.C. § 922(g)(3), which bars firearm possession by unlawful drug users. The case involved a Texas man who admitted marijuana use while keeping a handgun at home. The Court held the government applied the law too broadly by treating recreational users like people with addiction-related public-safety risks.
Why it matters: The decision clarifies how courts should apply Bruen’s history-and-tradition test in Second Amendment cases. It addressed only the unlawful-user prong and left intact prohibitions involving addiction or firearm possession while intoxicated.
Implication: The ruling may limit prosecutions based solely on unlawful drug use where the government lacks evidence linking that use to dangerousness or firearm-related risks. Future cases will likely turn on distinctions between recreational use, addiction, impairment, and public-safety risk.

The Docket
DOJ Seeks Dismissal of Clean Air Act Suit Against xAI Data Center
The U.S. Department of Justice moved to dismiss an NAACP Clean Air Act citizen suit against xAI, arguing its Mississippi data center supports AI systems tied to national-security functions. The suit alleges xAI operates natural gas turbines without required air permits.
Why it matters: The filing tests whether executive branch national-security assertions can limit private enforcement of federal environmental statutes. If accepted, the argument could narrow Clean Air Act citizen-suit litigation against data centers and other infrastructure linked to AI or defense operations.

Supreme Court to Review Six-Person Criminal Juries
The U.S. Supreme Court agreed to hear Kian v. Florida, which asks whether the Sixth Amendment requires 12-person juries in serious criminal cases. The petitioner seeks to overturn Williams v. Florida, the 1970 decision upholding six-person criminal juries.
Why it matters: The case will test whether the Court’s recent originalist approach to the Sixth Amendment extends to jury size. Overturning Williams would alter criminal trial procedures in Florida and five other states and could trigger challenges to convictions returned by six-person juries.

Supreme Court to Review Prolonged Immigration Detention
The U.S. Supreme Court agreed to hear a Trump administration appeal challenging a Second Circuit ruling on prolonged immigration detention. The case asks whether noncitizens convicted of aggravated felonies have a Fifth Amendment right to bond hearings during pending removal proceedings.
Why it matters: The Court will decide whether the government must prove flight risk or danger to the community by clear and convincing evidence to continue detention. A ruling against the administration could add procedural requirements in immigration habeas litigation, removal proceedings, and ICE detention practices.

DOJ Sues New York Officials, Vendor Over $11 Billion Medicaid Program
The U.S. Department of Justice sued the New York State Department of Health, state officials, and Public Partnerships LLC over the state’s $11 billion Consumer Directed Personal Assistance Program. The complaint alleges Public Partnerships misrepresented its readiness to administer the program and that state officials failed to address misuse of federal Medicaid funds.
Why it matters: The lawsuit highlights federal scrutiny of state Medicaid administration, procurement, and vendor oversight. State agencies and contractors may face greater litigation risk over procurement representations, contract monitoring, and compliance with federal funding requirements.

SEC Prepares Innovation Exemption for Tokenized Stock Trading
The Securities and Exchange Commission is expected to issue an innovation exemption allowing crypto firms to offer blockchain-based instruments that track U.S. stocks. The temporary policy would permit trading in tokenized equities without full compliance with rules governing registered exchanges, broker-dealers, and other securities intermediaries.
Why it matters: The exemption would allow the SEC to test digital-asset trading models without formal rulemaking. Counsel advising platforms, brokerages, and issuers will need to assess the agency’s approach to liquidity, custody, investor disclosures, and parity between tokenized instruments and traditional shareholder rights.
