Defendant appealed the decision of the Appeals Panel sustaining the violation of R.I.G.L. 1956 § 31-27-2.1 (refusal to submit to a chemical test). The Court held that there was reasonable suspicion to stop the defendant because the officer corroborated the anonymous tip when he observed the defendant lose his balance on his motorcycle.  Accordingly, the decision of the Appeals Panel sustaining the charge against the defendant was affirmed.
