R.I. Gen. Laws § 44-33-15: Appeals.

Any person aggrieved by the decision of the tax administrator denying in whole or in part relief claimed under this chapter, except when the denial is based upon late filing of claim for relief or is based upon a redetermination of rent constituting property taxes accrued as not at arms length, may appeal the decision of the tax administrator to the sixth division of the district court by filing a petition within thirty (30) days after the denial.
