§ 136.110 Commitment of defendant after release

If you're a defendant who was released before trial (for example, out on bail), showing up for trial doesn't guarantee you'll stay free for the rest of the case. Once you appear in court for trial, the judge has the power to order you taken into custody right then, even if you were following all the rules of your release.

This means the court can decide, at its own discretion, that you need to be held until the case is fully decided or until a judge issues another order. If this happens, you'll be taken into custody immediately and kept there until the court says otherwise.

In short, being released before trial doesn't mean you're guaranteed to remain free once the trial actually starts. The judge can change that at any point after you appear, based on what they think is necessary for the case.
