However, mediation shall not be required in small claims actions under the Vermont Rules of Small Claims Procedure, in cases where parties have already engaged in mediation, foreclosure and evictioncases, actions to renew a judgment, and proceedings for a writ of habeas corpus or post-conviction relief.
