The Supreme Court ruled 6-2 Tuesday to limit the president’s ability to appoint some high-level officials to serve as acting heads of agencies while awaiting Senate approval. The case stemmed from President Obama’s 2011 appointment of Lafe Solomon to the National Labor Relations Board. Justices Sonia Sotomayor and Ruth Bader Ginsburg dissented from the majority ruling, which rules a person can’t serve as acting head of a federal agency while he or she is also awaiting Senate confirmation to fill the role permanently.
