The Harvard Journal of Law and Public Policy has just published my article on the original meaning of the Recess Appointments Clause. It reports that the Constitution uses the term “the Recess” to refer only to formal breaks between sessions of the Senate, not to informal intra-session breaks. It also reports that a vacancy “happens” only when it is created during the Recess. It is not sufficient for the vacancy to be created when the Senate is in session and then continue into the recess.
These conclusions are based on detailed, impartial, study of Founding-Era legislative and other governmental practice—apparently the first article on this topic to report the results of such a study.
