The report states that the case could also decrease the frequency of presidential recess appointments. Since 1981, more than half of all recess appointments have been made in Senate recesses that were during a session, something the president would no longer be able to do. “Thus, by limiting both the periods in which a President may make recess appointments, and the vacancies that may be filled by such appointments, the decision likely would strengthen the Senate’s ‘Advice and Consent’ role, while restricting the President’s authority to make unilateral appointments.”
The Brooklyn Law School Library has in its collection Justice Takes a Recess: Judicial Recess Appointments from George Washington to George W. Bush (Call #KF8776 .G666 2009) by Scott E. Graves and Robert M. Howard. The book explains how the Constitution allows the president to “fill up all Vacancies that may happen during the Recess of the Senate, by granting Commissions which shall expire at the End of their next Session.” Examining every judicial recess appointment from 1789 to 2005, the book addresses how presidents have used recess appointments over time and whether the independence of judicial recess appointees is compromised. They argue that these appointments can upset the separation of powers envisioned by the Framers, shifting power away from one branch of government and toward another.
