The U.S. Supreme Court declined to hear several cases on Monday, including a dispute involving Michigan legislators and election measures adopted by state voters. The court left in place a Sixth Circuit ruling that the individual lawmakers lacked standing to sue. Additionally, the Supreme Court refused to review a case concerning whether Consumer Product Safety Commission warnings to a fireworks importer are judicially reviewable final agency actions. Notably, the court summarily affirmed a lower court's ruling clearing journalist Ta-Nehisi Coates, Oprah Winfrey, and several companies of plagiarism after five justices recused themselves from the decision. The recusals were related to a case involving the parent company of the justices' book publisher, marking the most significant recusals since the court adopted a new ethics code in 2023. The recusals left the court without the quorum of six justices needed to decide whether to hear the lawsuit against Coates. The Supreme Court's refusal to hear these cases leaves previous lower court rulings intact.
