Mohammad Ashik bin Aris v Public Prosecutor

Mohammad Ashik bin Aris v Public Prosecutor

The Court held that the HSA's pre-30 June 2010 urine-testing procedures complied with s31(4)(b); s16 and s22 operate independently; non-compliance with s31(4)(b) does not automatically render s16 certificates inadmissible or incapable of triggering the s16 presumption though non-compliance may be relied upon to rebut s16 in specific cases demonstrating forensic inaccuracy or misidentification; and admissible confessions supported by objective evidence can alone prove the actus reus of the s8(b) offence beyond reasonable doubt.

Procedural Posture

Criminal Appeal / Court of Appeal Judgment on Appeal From High Court

Legal Issues

  1. 1 Whether HSA urine-testing procedures complied with s31(4)(b)
  2. 2 Whether non-compliance with s31(4)(b) voids admissibility or presumptive effect of s16 certificates
  3. 3 Whether s16 and s22 presumptions operate independently and effect of rebuttal

Ratio Decidendi

The Court held that the HSA's pre-30 June 2010 urine-testing procedures complied with s31(4)(b); s16 and s22 operate independently; non-compliance with s31(4)(b) does not automatically render s16 certificates inadmissible or incapable of triggering the s16 presumption though non-compliance may be relied upon to rebut s16 in specific cases demonstrating forensic inaccuracy or misidentification; and admissible confessions supported by objective evidence can alone prove the actus reus of the s8(b) offence beyond reasonable doubt.
