Upon the filing of an independent action by a party, the court shall vacate a mediated agreement reached in a dispute resolution proceeding pursuant to this chapter, or vacate an order incorporating or resulting from such agreement, where:
For purposes of this section, "misconduct" includes failure of the neutral to inform the parties in writing at the commencement of the mediation process that:
The fact that any provisions of a mediated agreement were such that they could not or would not be granted by a court of law or equity is not, in and of itself, grounds for vacating an agreement.
A motion to vacate under this section shall be made within two years after the mediated agreement is entered into, except that, if predicated upon fraud, it shall be made within two years after these grounds are discovered or reasonably should have been discovered.
