R.I. Gen. Laws § 28-9.6-15: Attorneys’ fees, costs, and interest.

In the event either the bargaining agent or the state authorities files a petition for writ of certiorari to the supreme court of the state of Rhode Island for a review or modification of a majority decision of the arbitrators, which by the provisions of § 28-9.6-9 is binding upon both the bargaining agent and the state authorities, the party against whom the decision of the supreme court is adverse, if the supreme court finds the appeal or petition to be frivolous, shall pay reasonable attorneys’ fees and costs to the successful party as determined by the supreme court and the supreme court shall in its final decision or judgment award the costs and reasonable attorneys’ fees. If the final decision affirms the award of money, the award, if retroactive, shall bear interest at the rate of eight percent (8%) per annum from the effective retroactive date.
