Can you be charge for the same crime twice if it was thrown out a year ago in another county?

It depends if a felony or misdemeanor and why it is being refiled.

Yes. Double jeopardy only applies if trial on the charges actually started before the charges were dismissed, then they get refiled.

If a charge is dismissed you cannot be tried for the same charge again. But, that applies to a charge relating to the same incident as the one that was dismissed. If, for instance, you steal a car, get caught, get charged and the charge is dismissed, the prosecution cannot retry you for that same incident. But, if you steal the car a second time, of course they can charge you for that. Since you say the two charges relate to incidents in two different counties, they are two separate crimes. Therefore, you can be charged for both of them. Consult an attorney to protect your rights.

It will depend on why it was "thrown out" and whether double jeopardy attached to the original charge. I strongly suggest that you contact an experienced criminal law attorney for a face-to-face consultation and give him/her all of the facts surrounding your case. He/she would then be in a better position to analyze your case and advise you of your options.

If it was a felony, then it can be dismissed once and refiled again.
