Prior to 14th of November 1994, a person was driving or attempting to drive a motor vehicle with howsoever small quantity of alcohol in his blood was guilty of an offence u/s.185. However, by reason of an amendment made in section 185 by Act 54 of 1994 w.e.f. 14/11/1994 a person is not guilty of an offence under section 185 of the Motor Vehicles Act unless the quantity of alcohol in his blood exceeds 30 mg per 100 ml of blood detected in a test by breath analyser.

In my view, therefore, the particulars of the offence of which he was
