Art. 555 Waivers

This rule deals with mistakes that happen when a defendant is formally charged in court, a step called arraignment. If something is done wrong during this process, like the court skipping the reading of the charges, the defendant loses the right to complain about it later. This happens if the defendant goes ahead and enters a plea without pointing out the problem at the time.

The same idea applies if the arraignment never happens at all, or if the defendant never actually enters a plea. If the trial starts and the defendant doesn't raise an objection about it, the court will treat the situation as if the defendant had pleaded not guilty.

Basically, this rule tells defendants that they need to speak up right away if something about the arraignment process wasn't done correctly. Staying quiet and moving forward with the case means giving up the chance to challenge that mistake later on.
