I agree here now. The Oregon case I cited ONLY deals with other types of mistrials, NOT hung juries, so I stand corrected.
I knew I had read something before about multiple prosecutions after hung juries and it turns out after some more research it could be a possible Due Process violation, state and federal.
The DJ clause does not forbid repeated prosecutions after hung juries, that is settled law, the DP clause may though. I had done some research on that some years ago and related it here to DJ instead of DP.
From what I found, no jurisdiction permitted more than 4 retrials after hung juries based on fairness and DP.
