Defendant appealed the decision of the Appeals Panel sustaining the violation of  R.I.G.L. 1956 § 31-14-2 (prima facie limits). The Court held that the defendant’s discovery request for documentation regarding the calibration of the radar unit did not constitute a request for “material” documentation because the documents only offered recommendations for calibration and the state proved that the officer’s radar unit was properly calibrated through the officer’s testimony. Accordingly, the Court affirmed the decision of the trial judge sustaining the charge against defendant.
