§ 843 Trial on original indictment, when.

If prosecutors don't file a new charge for a more serious crime within one year, the case doesn't just disappear. Instead, the court goes back to the original charge and moves forward with trial on that.

This rule protects defendants from being stuck in limbo. Prosecutors sometimes want to charge someone with a bigger crime after looking at new evidence, but they only get so much time to do that. If they miss the deadline, the case returns to the charge that was already filed, and the trial happens on that original charge.

In short, this rule sets a limit on how long prosecutors can wait before upgrading charges. If they wait too long, the original charge stands and the case moves forward on that basis.
