Nandakishor s/o Raj Pat Ahir appealed to the High Court against his conviction and sentence in the District Court for an offence under s 8(b)(ii) of the Misuse of Drugs Act (MDA). The District Judge had convicted Nandakishor on the charge and sentenced him to seven years and six months’ imprisonment and six strokes of the cane. The High Court, presided over by Tay Yong Kwang J, dismissed the appeal against both conviction and sentence, finding that the variance in urine test results was correctly calculated and that the sentence was not manifestly excessive.
