A lot depends on your State name, which you never mentioned.
But generally speaking, the SOL depends upon the Causes of Action against you. For example, in some States, if the Cause of Action is Fraud, the SOL doesn't begin until the fraud is discovered, or should and could have been reasonably discovered. So, for all I know, and because you didn't mention the Cause of Action, the Plaintiff may well be within the SOL.
If the SOL is expired, then the Plaintiff has no legally viable Cause of Action, and only a judge can make that decision; not a mediator. A mediators sole role is to discuss the matter between the parties and to see if there is some avenue for settlement between the parties, and to make suggestions. The mediation cannot make any decisions. The mediator's role is merely to assist the parties to make their own decisions about the matter. Remember, a "mediator" is not an "arbitrator."
