I know that double jeopardy has been debated and discussed ad nauseum, but I suspect there is a factual answer for my hypothetical below. (Yes, I know hypotheticals are stupid, but I’m looking for some feedback anyway.)
My understanding is that an individual can be tried twice for the same crime, once under state law and once under federal law, without violating the double jeopardy clause of the 5th amendment. The rational is that the federal and state levels are two sovereign entities, each entitled to its own jurisdiction. Therefore, double jeopardy does not occur even if the same crime is tried at both levels.
Now for the hypothetical: Suppose a state allows for the existence of another entity within its borders, and said entity has its own jurisdiction – something similar to a municipality. (Municipalities have their own charters and are self-governing within the state) A crime occurs within this third entity’s borders, and said crime is also punishable at the state and federal levels. By the same logic that allows one trial at state level and a second trial at the federal level, this third entity would be entitled to try an individual for a third time for said crime based on laws within its jurisdiction.
Now suppose there exists a fourth, fifth, etc. jurisdictions below the third one. By the same logic as above, these jurisdictions would also have a right to try an individual for said crime, effectively allowing for infinite trials for the same crime, just in different jurisdictions within the hierarchy.
I think that most people would agree that this hypothetical set of infinite (re)trials would violate the spirit of the 5th amendment.
So, if the above hypothetical scenario violates the double jeopardy clause of the 5th amendment, then why don’t federal/state (re)trials for the same offence violate the double jeopardy clause?
(Am I wrong that a third jurisdiction could even exist below the state level? If that’s the case, then my hypothetical scenario cannot actually occur, and my question will have been answered.)
I didn’t intend for this to be a debate, but if it goes that way the mods can feel free to move it.
