If someone was on trial for murder and wasn’t sentenced yet, and they fell into a coma what would happen?
The precise answer will probably vary on the margins from jurisdiction to jurisdiction, but on the whole this is largely true: imposition (roughly equivalent to “pronouncement”) of sentence would be stayed until consciousness was restored. Continuances (i.e., postponements) in all things legal generally require “good cause” and there are few causes better than unconsciousness. Btw, although it’s not exactly what you asked I’ll throw in another tid-bit: If the sentence were death and it was actually pronounced, it could not be executed (not to be confused with “imposed”) until consciousness were restored (and maybe not even then).
Got that?
In the foregoing response, of course, I assume that the person “on trial for murder” had actually been convicted of murder before lapsing into the coma. If the coma occurred before verdict, the trial itself would be suspended.
