Jesus was sent to the Roman procurator Pilate as a state criminal. There was no evidence against him at all on this charge, other than the supposition that men claiming to be the Messiah sooner or later rose in rebellion–Messiah-claimants were usually packed off to the Roman authorities if they became troublesome enough. So Pilate was reluctant to convict but did so for political reasons. Hence Jesus was not stoned to death under Jewish law, but crucified by Rome.
