"I want my day in court, judged by 12." People say some version of that constantly, and it usually comes with an assumption underneath it: that the right to a speedy trial means there's a clock somewhere, counting down, and once it hits zero the case gets thrown out. There is a right to a speedy trial in New York. It just doesn't work anything like that.
What the right actually says
The right is real, and it comes from more than one source. Criminal Procedure Law § 30.20 states plainly that "after a criminal action is commenced, the defendant is entitled to a speedy trial," and that criminal cases must generally be given preference over civil ones, with cases where the defendant is held in custody given preference over other criminal cases. New York's Civil Rights Law § 12 guarantees it too, alongside the right to a public trial by an impartial jury and the right to confront witnesses. The Sixth Amendment to the U.S. Constitution guarantees the same right at the federal level. None of these sources attach a specific number of days to it.
This is not the same right as CPL 30.30
New York also has a statutory speedy trial rule, CPL 30.30, with real deadlines: six months for a felony, ninety days for most misdemeanors, and so on. That's a mechanical calculation, and it's the tool that actually gets cases dismissed on paper. The constitutional right described here is a completely different, older, and vaguer protection, and confusing the two means walking into court expecting a deadline that was never the one actually in play.
The test New York courts actually use
Since People v. Taranovich, 37 N.Y.2d 442 (1975), New York courts evaluate a constitutional speedy trial claim using a five-factor balancing test, not a countdown. Courts still apply it this way today; see, for example, People v. Johnson, 100 A.D.3d 492 (1st Dep't 2012), which walks through the analysis in a real case. The five factors are: the extent of the delay, the reason for the delay, the nature of the underlying charge, whether the defendant was held in custody for an extended period, and whether the delay actually impaired the defense. No single factor decides the outcome on its own. A court weighs all five together, against the specific facts of the case in front of it.
Why that matters more than it sounds like it should
A mechanical deadline is something a defendant can point to and win on the math alone. A balancing test is a judgment call, made by the same court system that has every institutional incentive to keep a case moving toward a plea rather than toward a dismissal. A "serious" charge can weigh against the defendant on its own, under the third factor, even when the delay itself was long and largely the prosecution's fault. This is a real right. It is also a much harder one to win on than most people assume when they first hear the phrase "speedy trial."
The exact question to ask
If a case has been sitting for months with no clear next step, ask your attorney directly: "Are we tracking this under the CPL 30.30 statutory clock, the constitutional Taranovich claim, or both, and what does the delay actually look like under each one?" They are two separate motions with two separate standards, and a case can be weak on one while still worth raising on the other.
The deeper reason this right so rarely gets exercised has less to do with the law itself and more to do with what happens before anyone gets near a trial date at all. The trial penalty behind New York's guilty-plea rate is the pressure that keeps most cases from ever testing either speedy trial standard in the first place.
