§ 131 Conviction or acquittal in one county as bar to prosecution in another.

Here's a plain English summary of this rule.

Sometimes a crime happens in a way that more than one county could legally handle the case. This might happen if the crime crossed county lines or involved actions in different places. When this occurs, prosecutors in each of those counties have the legal right to bring charges.

This rule says that once a case is finished in one county, that's the end of it. If you go to trial in one county and are found guilty, no other county can charge you again for that same crime. The same protection applies if you are found not guilty. Once a court in one county reaches a final decision, other counties cannot try to prosecute you again for that same offense.

This rule protects people from being tried over and over for the same crime just because more than one county had the ability to file charges. It gives you certainty that once your case is resolved, it's truly over, no matter how many counties could have prosecuted you.
