1) Statute of limitations apply to civil or criminal cases, only.
2) For example, in civil, if they pursued this under a claim for "unjust enrichment," they can only do so in 3 years after the event. G.S. 1-52(9).
3) In criminal matters, there can sometimes be no statute of limitations at all. N.C. Gen. Stat. § 15-1.
4) However, this is neither a civil or criminal matter. This is an administrative matter, meaning an action is being brought by an agency against someone's license not in a court of law, but under its own internal rules. As such, no statute of limitation laws apply. They can technically do this at any time, including 13 years later, I am afraid. While this makes the argument weaker since so much time has passed, it is still true that they can attempt to do this.
Please note: If I tell you simply what you wish to hear, this would be unfair to you. I need to be honest with you and sometimes this means providing information that is not optimal. Negative ratings are reserved for experts who are rude or for erroneous information. Please rate me on the quality of my information; do not punish me for my honesty.
I hope this helps and clarifies. Please use the SEND or REPLY button to keep chatting, or please RATE when finished. You may always ask follow ups at no charge after rating. Kindly rate my answer as one of TOP THREE FACES/STARS and then SUBMIT, as this is how experts get credit for our time. Rating my answer the bottom two faces/stars (or failing to submit the rating) does not give me credit and reflects poorly on me, even if my answer is correct. I work very hard to formulate an informative and honest answer for you; please reciprocate my good faith with a positive rating.
