回複：兩年前的車禍今天被人告了

You need to get an attorney who is good at cases on personal injury and familar with GA law.

You mentioned that there was a court decision two years ago. I don't know whether this case was brought to a complete trial before. If it was and the victim didn't claim damages based upon personal injury, he may not raise the issue again (claim preclusion). If not, he still has the right to recover damage. You may also need to talk to your insurance company. Good luck!
