I found that the accusation had to do with disputed points of their own law, and that there was no charge against him deserving death or imprisonment.
In context
27This man was seized by the Jews and was about to be killed by them when I arrived with my troops and rescued him, having learned that he was a Roman citizen. 28Wanting to know the charge on which they were accusing him, I brought him down to their Sanhedrin. 29I found that the accusation had to do with disputed points of their own law, and that there was no charge against him deserving death or imprisonment. 30When I was informed that there would be a plot against the man, I sent him to you at once, and instructed his accusers to state their case against him before you.” 31So the soldiers carried out their orders: they took Paul and brought him by night to Antipatris.
