'Investigation' in the Bible

Now therefore, you and the Council notify the commander to bring him down to you, as though you were going to determine his case by a more thorough investigation; and we for our part are ready to slay him before he comes near the place.”

Yet I have nothing definite about him to write to my lord. Therefore I have brought him before you all and especially before you, King Agrippa, so that after the investigation has taken place, I may have something to write.
