What is the maximum number of times someone could be tried for a single crime in the USA?
<p>So I know that, despite double jeopardy, it's possible to be tried twice for the same crime, by the state and the federal government.</p>
<p>Purely as an act of curiosity I'm wondering how many times one could end up on trial for a single crime due to the distinction of courts, assuming for some reason every court attempted to prosecute.  I know that is extremely unlikely, but for the sake of demonstrating a point lets say that everyone who has jurisdiction insists on filling charges.</p>
<p>As I see it if someone from state A shoots someone from state B inside of state C he could be tried by all three states, plus the federal government; for a total of four times.</p>
<p>He could also be sued for damages in civil court, possible in all three states?  So as many as 7 times if you count civil court as being 'tried'.</p>
<p>Are there any other situations/ways that could lead to a larger number of trials for any one crime?</p>

<p>So each government has jurisdiction of the crime if and only if it occurs within their borders.  In addition, the Federal Government can take a crack at any crime any where in the United States, though typically they only do so if the crime involves crossing state lines (kidnapping over state lines, ect).</p>

<p>At the maximum, suppose for arguments sake Alice fatally shoots Bob while Bob is standing at dead center of the Four Corners Monument (the only place in the United States where four states meet).  This means that one act of Murder has been committed in four seperate states, so Colorado, Utah, New Mexico, and Arizona can all claim jurisdiction over the case and each prosecute Alice for First Degree Murder.  Additionally, the Federal Government may step in and also prosecute Alice for First Degree Murder (though they are more likely not too.  The Feds rarely prosecute crimes after the State UNLESS the State did something horribly wrong...  I.E. Utah let her go because Utah is crazy).  Additionally, the monument marks the dividing line between the Navajo Nation and the Ute Tribe, both semi-autonomous Native American Tribes that have their own recognized court systems, so they could conceivably charge Alice with First Degree Murder.</p>

<p>So in total, the most amount of times someone can be charged for the same crime due to cross-jurisdiction is 7 times (Four States, 2 Tribal Governments, and one Federal Government).  In likely hood, a few of these guys will pass because it's a waste of effort.  If Alice gets the death penalty in Arizona, Colorado can't kill her a second time.  It's important to note that each government gets exactly one trial so Alice can't be convicted twice in Arizona.</p>

<p>A more realistic example occurred in the D.C. Beltway Sniper Case, where the perpetrators were tried in both Virginia and Maryland but only for the crimes committed within those states.  VA got first crack because they had (and eventually carried out) the Death Penalty.  Maryland tried both for insurance in case the VA cases got thrown out for reasons.  The Feds found this satisfying and decided not to press their charges.</p>

<p>States generally don't make it a crime to kill one of their residents outside that state, or make it a crime for one of their residents to kill someone outside of that state.  In your scenario, this would be a crime in state C and maybe a federal crime (the federal government would need some justification to get involved; maybe the victim is a federal employee) but not a crime in state A or B.</p>

<p>If you exploded a bomb at a state line, I suppose you could commit murders in multiple states with a single act.  However, the murder of Jane in Kentucky and Joe in Tennessee would not really be a "single crime"; that's two crimes (and it would be two crimes even if it didn't cross state lines.)</p>

<p>If you had a convoluted enough conspiracy to commit murder (you hire the best chemist from all 50 states to make the deadliest poison they can, then mix them together and feed it to your victim) it would be possible for you to be charged in all 50 states, plus the federal government.  However, this would require that an act to further the conspiracy be performed in each state.  So it's arguable whether this counts as a "single crime".</p>

<p>If the person somehow had a restraining order filed against him in all 50 states plus federal court, he could be tried in each state for violating the court orders with a single act.  Again, it's arguable whether that counts as a "single crime".</p>

<p>It's worth noting that territories such as Guam, Puerto Rico, or Washington DC count as being under federal jurisdiction already - you cannot be tried under DC law and then again under federal law for the same crime.  See <a href="https://supreme.justia.com/cases/federal/us/206/333/case.html" rel="nofollow noreferrer">Grafton v. United States, 206 U.S. 333 (1907)</a>.  And in <a href="https://supreme.justia.com/cases/federal/us/397/387/case.html" rel="nofollow noreferrer">Waller v. Florida, 397 U.S. 387 (1970)</a>, it was ruled that cities count as political subdivisions of the state, so you cannot be tried by the state and again by a city in the state.</p>

<p>However, in <a href="https://supreme.justia.com/cases/federal/us/435/313/case.html" rel="nofollow noreferrer">United States v. Wheeler, 435 U.S. 313 (1978)</a>, the Supreme Court ruled that Indian tribes can have their own sovereignty, and it is <em>not</em> a violation of double jeopardy to be tried and convicted under tribal law and again under federal law.  So, instead of the maximum number of trials in some convoluted scenario being 51 (50 states plus federal), you'd also have to add all tribes that still have sovereignty.  </p>

<p>Just have the jury keep hanging.  I don't think there's any limit to how many times a trial that ends in a hung jury mistrial can be retried.</p>

<p>Why are you being sued in 3 states? Are there 3 people who were separately harmed by your actions? If so, there's no requirement that those people need to be from different states - each can file their own action regardless. If you harm a million people, a million people can file a lawsuit against you. But if one person is trying to sue you in 3 different jurisdictions, the courts aren't going to allow that.</p>
