Finally, the same 1869 federal statute which mandated a 9-member Supreme Court has also established a quorum of only 6 members. Thus, there is no rush to fill any Supreme Court vacancy, in spite of the fact that some future cases might end up tied 4-to-4. Given that Congress has set a quorum of 6 members, it stands to reason that Congress expected some Justices: to recuse themselves in specific cases; to take temporary leave to fulfil other government duties; to recuperate for a reasonable time if ill; and to die. The Court, as a functioning institution, goes on, at least, as long as it has 6 members, and surely Congress must have understood that a 6 or 8 member Court can deadlock. Indeed, historically, there have been lengthy periods of time where the Court, by statute, was expressly composed of an even number of members. For example, when Chief Justice John Marshall was appointed to the Supreme Court, its size was set to 6 members by statute. To the extent worries about deadlock are a consideration, it is a political consideration for the American People, not a legal consideration, constitutional or otherwise.
