The Senate has a long-standing practice of permitting motions to reconsider previous decisions. In 1931, the Senate granted advice and consent to the president on the appointment of a member of the Federal Power Commission. The officer in question was sworn in, but the Senate, under the guise of a motion to reconsider, rescinded the advice and consent. In the writ of quo warranto proceedings that followed, the Supreme Court ruled that the Senate was not permitted to rescind advice and consent after the officer had been installed.
