The Senate has actually tied in an impeachment trial — twice

The Senate will soon vote on whether to call witnesses in President Donald Trump’s impeachment trial. This vote could be 50-50.

If a tie occurs, Chief Justice John Roberts can cast a vote to break the tie, based on a careful reading of the Constitution and impeachment precedent. It has happened before.

The Founders’ words

I am a constitutional scholar and the author of a book on John A. Bingham, one of the impeachment managers in the trial of President Andrew Johnson. Let’s start by looking the constitutional text.

Article 1, Section 3 of the Constitution gives the vice president a tie-breaking vote if the Senate is equally divided.

However, the vice president doesn’t preside over a presidential impeachment because of his conflict of interest: He would become president if the trial resulted in a conviction.

Instead, the chief justice of the United States presides. In doing so, the natural inference is that he takes on all of the powers of the vice president. If he didn’t, presidential impeachment trials would be the only cases in which tie votes could not be broken. That’s an illogical result.

Some claim that the chief justice should be treated like an ordinary senator who presides over the Senate and cannot break ties. In my view, this comparison is deeply flawed. When a senator presides over the Senate (when the vice president is absent), that person does not get a tie-breaking vote because they already get one vote as a senator.

But neither the chief justice nor the vice president has a vote at all, unless there is a tie. The posture of the chief justice and the vice president toward the Senate is the same and, therefore, they logically must have the same power to break ties.

Two tie-breakers from a chief justice

The Senate rules on impeachment trials say nothing about what should occur in the event of a tie. But the Senate often relies on its precedents, rather than written rules, to govern its proceedings. So the lack of a rule specifying the chief justice’s tie-breaking power does not mean that he lacks that power.

During President Andrew Johnson’s impeachment trial in 1868, Chief Justice Salmon P. Chase broke two tie votes on procedural questions.

Some senators objected to the chief justice’s tie-breaking, so the Senate debated whether he could – and ultimately upheld Chase’s authority to break ties.

There were no tie votes during President Bill Clinton’s impeachment trial in 1999, so there is no other example to contradict the 1868 precedent.

Though the chief justice can break ties in the Senate, that says nothing about whether he must do so, nor how he should do so. These are questions that must be addressed separately depending on what the tie is about.
