Double jeopardy applies to criminal prosecutions. There is some limitation on evidence of character being used if it is more than ten years old, but that is in judicial actions and is only one consideration. You don't say what context this issue is being raised in, and your remedies may vary depending on the context of the problem. The grandfathering concept seems unlikely to apply in any context that I can imagine.

Unfortunately there is much more information needed in order to properly ascertain whether you have a double jeopardy issue here. My suggestion is to contact an attorney in Panama City and have a free consultation to discuss your options. Make sure to bring all of your documentation with you.
