How many US Supreme Court Justices must vote yes to have a case heard in the Court?
Here I believe we are talking about the “rule of four.” I believe that it means it takes at least (4) U.S. Supreme Court Justices to agree on hearing a case before it actually is heard before the US Supreme Court. From what I have read, it is the primary means by which a case comes before the United States Supreme Court. Individuals, litigants or petitioners who seek review by the Supreme Court petition the Court for the writ, and if granted, the case comes before the them for disposition. Such was the Florida case of Gideon vs. Wainwright.
