Sometime in the next week or two, the impeachment trial of President Donald Trump will convene in the Senate. When it does, Chief Justice John Roberts will preside. There has been a good deal written about Roberts’ role, some of it intimating – or at least hoping – that Roberts could wrench control from the politicians who make up the Senate and transform the proceeding into a trial of the conventional judicial sort, with both sides able to compel the appearance of live witnesses and the production of documents and to inquire into any matter logically relevant to the charges against the president.
For better or worse, neither the Constitution, the rules of the Senate, historical precedent nor the personal predilections of Roberts himself make this the least bit likely. Instead, Roberts is most likely to serve as a dignified figurehead in an affair entirely dominated by the Republican senatorial caucus. Here’s why.
The Constitution specifies only four points about the Senate impeachment trial of a president: (1) The Senate “shall have the sole power to try all impeachments”; (2) when sitting as a court of impeachment, senators “shall be on oath or affirmation”; (3) conviction of any accused officer requires “concurrence of two thirds of the members present”; and (4) when the president is the accused, “the Chief Justice shall preside.”
It is crucial to note why the chief justice appears only in presidential impeachment proceedings. The simple answer has to do with the often-forgotten constitutional power of the vice president to serve as president – meaning presiding officer — of the Senate. In any impeachment case other than that of the president, the vice president can preside, as Thomas Jefferson did in the very first impeachment, that of Senator William Blount in 1799, and as Aaron Burr later did in the 1805 trial of Justice Samuel Chase. However, the Framers recognized that it would be unseemly at best for the person who would assume the presidency in the event of conviction by the Senate to preside over the president’s trial. To prevent that obvious conflict of interest, they specified the chief justice as a stand-in presiding officer in presidential impeachment trials.
A good many discussions of the upcoming Senate proceeding have understandably, but incorrectly, inferred two things from the presence of a judge in the presiding officer’s seat: first, that having a judge preside implies that the process will be akin to a conventional judicial trial, and second, that the chief justice’s role will be akin to that of a judge in such a trial. Neither inference is supported by the constitutional text.
Impeachment trials of presidents may excite more public interest than impeachment trials of other “civil officers,” but they are no different in constitutional form. The standard of impeachable conduct is the same – “treason, bribery, or other high crimes and misdemeanors” – as is the two-thirds threshold for conviction. The chief justice is inserted into presidential impeachments only to resolve the conflict of interest. His presence in the chair does not make the proceeding more “judicial” in character, nor is he accorded more “judicial” authority than the vice president or president pro tempore (meaning “president for a time”) of the Senate would possess in cases involving other officials. His role is merely to serve the same function they do in such cases. That function is delimited by Senate rules.
