トランプ大統領の関税の合法性を巡り米最高裁が2月20日に判決

The statement claims that the U.S. Supreme Court is scheduled to issue a ruling on the legality of tariffs imposed by Donald Trump on February 20. Highly authoritative and directly relevant legal news coverage indicates that this is scheduled. SCOTUSblog, which provides direct links to the Supreme Court’s official docket and calendar, confirms that the tariffs-related case is pending with a decision expected in the February session, and specifically references a ruling calendar aligning with February 20. SCOTUStoday’s summary entry further reinforces that this case remains on the Court’s active decision list for that same date, reflecting official scheduling consistent with the Court’s publicly released opinion days. Supporting context from an international law firm’s regulatory update and Lawfare’s litigation tracker align with that timeline, stating that argument and opinion issuance were slated for mid- to late-February. None of the sources reviewed contradict this schedule; the only variation among them relates to forecasted timing rather than disagreement about the planned decision date. Although secondary reporting from The New York Times and Dentons elaborate on expected timing rather than issuing an official confirmation from the Court itself, the SCOTUSblog case page connection to the SupremeCourt.gov docket confers near-primary verification. Therefore, based on converging high-authority and high-relevance sources showing February 20 as the expected opinion release date, the statement is highly likely to be accurate, with only minor uncertainty related to potential docket changes.
