At a hearing held pursuant to Vehicle and Traffic Law § 1194, the hearing officer is required to determine, inter alia, whether the police lawfully arrested the operator of the motor vehicle for operating such vehicle while under the influence of alcohol or drugs in violation of Vehicle and Traffic Law § 1192 … . In order for an arrest to be lawful, the initial stop must itself be lawful (see People v De Bour, 40 NY2d 210, 222). Under the circumstances of this case, where the officer prevented the petitioner from departing, activated his vehicle’s emergency lights, and shined a light into the petitioner’s parked vehicle, a forcible stop and detention occurred … . The Department of Motor Vehicles, however, failed to establish that there was reasonable suspicion to justify the forcible stop and detention of the petitioner’s person or vehicle … and, accordingly, the challenged determination cannot be sustained. Matter of Stewart v Fiala, 2015 NY Slip Op 04857, 2nd Dept 6-10-15

“Retroactive statutes are those which impair vested rights or alter past transactions or considerations” … . Here, however, petitioner’s driver’s license is not generally viewed as a vested right, but merely a personal privilege subject to reasonable restrictions and revocation by respondent under her discretionary powers (see Vehicle and Traffic Law §§ 510 [c]; 1192 [2]…). Thus, respondent remained free to apply her most recent regulations when exercising her discretion in deciding whether to grant or deny petitioner’s application for relicensing. This is especially so in light of the rational, seven-month moratorium placed on all similarly-situated applicants for relicensing — i.e., persons with three or more alcohol-related driving convictions (see NY Reg, Mar. 13, 2013 at 46…). Furthermore, inasmuch as the revised regulations operated only to nominally change the effect of petitioner’s past acts on his future eligibility to obtain a driver’s license and was not imposed as punishment but, rather, to promote public safety, respondent’s application of 15 NYCRR 136.5 (b) (2) was proper under these circumstances (see … State Administrative Procedure Act § 202 [6]).
