What is the procedure when valid testimony is presented against the defendant?

Primary text

If the testimony is sound and the judge confirms the witnesses' integrity, the judge informs the defendant, 'They have testified against you; if you have anything to discredit their testimony, present it to me.' If the defendant requests a delay to investigate, a delay of two or three days is granted. If no grounds for invalidation are found, the judge rules against the defendant, as the right has been clearly established.
