R.I. Gen. Laws § 44-49-13 — Injunction prohibited — Burden of proof

(a) Injunction prohibited. No person may bring suit to enjoin the assessment or collection of any taxes, interest,
or penalties imposed by this chapter.
(b) Standard of proof. The tax and penalties assessed by the tax administrator are presumed to be valid and
correctly determined and assessed. The burden is upon the taxpayer to show their incorrectness
or invalidity. Any statement filed by the tax administrator with the court administrator,
or any other certificate by the tax administrator of the amount of tax and penalties
determined or assessed, is admissible in evidence and is prima facie evidence of the
facts it contains.
