<P> In addition to the constitutional guarantee, various state and federal statutes confer a more specific right to a speedy trial . In New York, the prosecution must be "ready for trial" within six months on all felonies except murder, or the charges are dismissed by action of law without regard to the merits of the case . This is also known as a "ready rule". In California courts, defendants have a right to a trial within 100 days to a year . </P> <P> The federal law detailing this right is the Speedy Trial Act of 1974 . All U.S. states have either statutes or constitutional provisions detailing this right . In 1979 the Act was amended to ensure that the defendant had time to provide a suitable defense . This amendment made it so trial could not start within less than 30 days after the defendant first appeared in the court . </P> <P> In Doggett v. United States (1991--1992) the Supreme Court determined that Doggett's eight and a half year wait for a trial violated his sixth amendment rights (the speedy trial clause), and they gave him a writ of certiorari . </P> <P> In Zedner v. United States (2006) the Supreme Court determined that a defendant cannot waive his right to a speedy trial using the Speedy Trial Clause because the clause protects all parties involved in a case to ensure that no one's interests are being implicated . </P>
