End of the Line: Winston Wins Unanimous Supreme Court Victory Against NJ Transit

In a unanimous decision authored by Justice Sotomayor, the U.S. Supreme Court held that NJ Transit is not an arm of the State of New Jersey and therefore is not entitled to sovereign immunity. The ruling means that plaintiffs injured by NJ Transit outside of New Jersey—such as in Pennsylvania and New York—may pursue claims in the courts of the states where their injuries occurred. The court adopted Winston’s position that state-created corporations that are formally liable for their own judgments are not arms of the state, reversing the Pennsylvania Supreme Court’s dismissal of Cedric Galette’s negligence suit while affirming the New York Court of Appeals’ decision allowing Jeffrey Colt’s case to proceed....Read more

UK Crypto Regulation Moves Forward: New Cryptoasset Regulated Activities: The FCA Gateway

HM Treasury published  the statutory instrument ‘the Financial Services and Markets Act (Cryptoassets) Regulations 2026’ (SI. 2026 No 102) (FSMA (Cryptoassets))’. This instrument will amend the Financial Services and Markets Act (FSMA) and bring cryptoassets within the regulatory perimeter. Whilst the regulations will not go into effect until 25 October 2027, the FSMA (Cryptoassets) marks a key legislative shift. It will subject cryptoasset firms to similar standards as traditional financial institutions, meaning that firms will now be required to seek authorisation from the FCA if they engage in the new cryptoasset regulated activities. On 8 January 2026, the FCA provided further detail on its proposed “gateway,” the application process through which firms will seek authorisation to carry on newly regulated cryptoasset activities under the UK’s forthcoming regime. A dedicated application window is planned to open on 30 September 2026, allowing the FCA to assess applications ahead of the new authorisation regime coming into force.

In this piece, we provide a detailed analysis of what this new gateway means for firms, and how they can take advantage of this early application period. Firms that apply during this application window are expected to undergo a smoother transition into the new regulatory sphere and will retain the full set of rights and allowances for conducting cryptoasset activities. Those applying after this period will face more limited permissions, with the scope of authorised activities varying depending on when their application is submitted. While the FCA has not yet outlined the detailed requirements of the application itself, its latest guidance provides a clear picture of what the transition period will involve for cryptoasset firms.

Paramount Global U.S. Supreme Court case. The case asks the justices to consider what criteria consumers need to meet in order to sue under the federal Video Privacy Protection Act (VPPA), a law enacted in 1988 that prohibits the unauthorized disclosure of certain personal information belonging to “consumers” that rent, purchase, or subscribe to “goods and services from a video tape service provider,” and whether that statute applies to a consumer who doesn’t directly subscribe to audiovisual goods or services....Read more
