What is the appropriate dismissal of a charge of criminal possession of a controlled substance in the seventh degree?

In this case, however, I find that dismissal due to a legal impediment is appropriate. A legal impediment to conviction is a determination that precludes a finding of guilt as a matter of law (see, People v. Amerada Hess Corp., 3 Misc.3d 134(A), 2004 WL 1197444 [App.Term 9th & 10th Jud.Dists.2004] ). The undisputed facts developed throughout this proceeding establish that the drugs were recovered from the defendant during a medical emergency and in response to a call for medical assistance. Therefore, she may not be convicted of the offenses of criminal possession of a controlled substance in the seventh degree.
