Following on my defense yesterday of the constitutionality of the filibuster for judicial nominations, now I consider what the founders had to say on the subject. Here I divide the question into two parts. First, was there an implicit or explicit assumption that the Senate would use a simple majority? Second, what is meant by "consent" for nominations?
Let's grant at the outset that the common parliamentary practice at the time used simple majority rule by default. There was some dispute, however, whether that ought to be the case in the new Congress. During the Constitutional Convention debates on June 6, 1787, Hugh Williamson of North Carolina proposed that all business in the new Congress be conducted using a 2/3rd majority, though the proposal was not seriously considered.
More significantly, Charles Pinckney's draft constitution, which was influential on the final product, included a clause which began, "Points in which the Assent of more than a bare Majority shall be necessary." Though we do not know from the records how broad this category would have been, there is a sense elsewhere in the record that Pinckney and other believed that some business ought not be left to a simple majority. For example, Pinckney writes in a pamphlet entitled "Observations on the Plan of Government Submitted to the Federal Convention" summarizing his views:
In all important questions where the present Confederation has made the assent of Nine States necessary, I have made the assent of Two-Thirds of both Houses, when assembled in Congress, and added to the number, the Regulation of Trade, and Acts for levying an Impost and raising a Revenue: -- These restraints have ever appeared to me proper; and in determining questions whereon the political happiness and perhaps existence of the Union may depend, I think it unwise ever to leave the decision to a mere majority; no Acts of this kind should pass, unless Two-Thirds of both Houses are of opinion they are beneficial, it may then be presumed the measure is right; but when merely a majority determines, it will be doubtful, and in questions of this magnitude where their propriety is doubtful, it will in general be safest not to adopt them.
So, too, did George Mason of Virginia object to the use of simple majorities for some business of Congress. Admittedly, at no time during these debates over the size of majority was the question of nominations addressed directly.
What should we make of the obvious silence in the Constitution about what sort of decision rule is to be used to conduct business? A quite reasonable reading assumes that a simple majority is to be used except where specified otherwise (e.g., veto override). Another interpretation which is supported by Senate practice since then is that by remaining largely silent on the matter and leaving the procedures of the House and Senate up to themselves, as Article I, Section 5 states, the Constitution leaves the two chambers free to decide for themselves whether to adopt another standard. The Senate, perhaps implicitly and perhaps in error, made such a decision when revising its rules in 1806 and abolishing a rule permitting a majority to end debate. That, of course, opened the door for the filibuster.
Now let's turn our attention to the question of what may be considered "consent" by the Senate. Hatch makes the strong claim that consent implies providing the opportunity for an up-or-down vote on the floor on a nomination. Most of the debate at the Constitutional Convention over what became Article II, Section 2, Clause 2 centered on whether appointments ought to be made by the executive or the legislature, before the familiar formula was decided upon. Madison approached the idea initially by proposing a submajority for confirmation:
Mr. Madison, suggested that the Judges might be appointed
by the Executives with the concurrence of 1/3 at
least of the 2d. branch. This would unite the advantage of
responsibility in the Executive with the security afforded
in the 2d. branch agst. any incautious or corrupt nomination
by the Executive.
After Nathanial Gorham of Massachusetts suggested the shared power of his state's constitution, which was defeated on a tie vote, Madison made this proposal:
Mr. Madison moved that the Judges should be nominated
by the Executive, & such nomination should become
an appointment if not disagreed to within days by 2/3
of the 2d. branch. Mr. Govr. Morris 2ded. the motion.
The next day, he explained his thinking:
in case of any flagrant partiality
or error, in the nomination, it might be fairly presumed
that 2/3 of the 2d. branch would join in putting a negative
on it.
This was, on the face of it, the inverse of his first proposal, but it put the burden on the Senate to act in the negative, to disapprove of a nomination, rather than to approve it. Moreover, the threshold used was open to negotiation:
Mr. Madison observed that he was not anxious that 2/3
should be necessary to disagree to a nomination. He had
given this form to his motion chiefly to vary it the more
clearly from one which had just been rejected. He was
content to obviate the objection last made, and accordingly
so varied the motion as to let a majority reject.
Madison's proposal was, however, rejected after more discussion and for the time being the Senate retained the power to make judicial appointments itself.
Later, when the question returned to the manner of appointment, language was adopted giving the president the power to appoint and the Senate the power to confirm. There is no record of discussion about what the size of majority ought to be as there had been previously. That said, there was debate over whether 2/3rds ought to be required for treaties, and implicitly the alternative was simple majority. Again, by one reading this meant that a simple majority was understood for the Senate's other powers in the clause as well.
But does that mean the Senate had a responsibility to provide a simple majority vote for all nominations? The record appears to say otherwise. First, return to Madison's earlier proposals. The delegates made a clear choice to give the Senate a positive power -- consent -- rather than a negative power. This is important because it means the Constitution does not explicitly require the Senate to record a vote to reject; the delegates clearly opted otherwise.
Second, the interpretation used after ratification indicates that they did not think such negative action was required on a nomination. Take this letter from George Mason to James Monroe:
This gives to the President alone the
Right of Nomination. And if the Senate were to refuse their
Approbation of the person nominated (which the subsequent
Part of the Clause puts in their Power) they wou'd
have no Right to nominate another Person; the Right of
Nomination being complete in the President [emphases in original].
Note that he says "refuse their Approbation," again meaning that inaction as well as active rejection would be sufficient. In probably the clearest language on the subject, take the commentaries on the Constitution written by Supreme Court Justice Joseph Story in 1833:
[The Senate] may withhold their advice and consent from any candidate, who in their judgment does not possess due qualifications for office.
So there we are. In requiring that someone may take the federal bench only upon confirmation by the Senate, the Constitution does not obligate the Senate to vote on every nomination, much less to record a vote for each nominee they reject. Such a proposal was rejected at the Constitutional Convention, and the language and subsequent interpretation of the clause do not support it.
(It is true that Hamilton in Federalist 76 saw the Senate's role in confirmations as little more than a rubber stamp for the president, in keeping with his preference for a strong and energetic executive, but this was not a view shared widely by the founders as a careful reading of the convention debates shows.)
