In People v. Dodt, (61 N.Y.2d 408), a Fourth Amendment case, the Court, in dictum, had noted the People's failure to meet their heavy burden to establish defendant's consent to accompany the police to the precinct after an unlawful automobile stop and arrest. Determinative for the Court in Dodt had been the People's failure to offer any evidence that defendant had been given the option of refusing to consent to accompany police to the precinct.
