Mohd Zain bin Ibrahim

On the court record

A criminal-prosecution practice across all three court tiers, combining drug and homicide work with habeas corpus and detention matters.

Mohd Zain bin Ibrahim appears across the Court of Appeal (Mahkamah Rayuan), the High Court (Mahkamah Tinggi) and the Federal Court (Mahkamah Persekutuan), and the reported decisions place him mainly on the prosecution side and as respondent in criminal matters. The core subjects are drug trafficking under "seksyen 39B(1)(a) Akta Dadah Berbahaya 1952" (section 39B(1)(a) of the Dangerous Drugs Act 1952) and homicide under "seksyen 302 Kanun Keseksaan" (section 302 of the Penal Code).

A distinctive strand is liberty and detention: the reported matters include habeas corpus proceedings, in which the lawfulness of a person's custody is tested, together with custody-and-control questions in the drug work. There is also work engaging offences under "seksyen 14(a)" of the relevant enactment and applications by notice of motion ("notis usul"). Appearing as respondent and for the prosecution, the reported task is to defend a conviction or an order of detention against challenge.

The work combines the ordinary serious-crime prosecution with the constitutional-adjacent questions that arise when the liberty of the subject is in issue. In the drug and homicide matters the argument engages the presumptions, the custody-and-control element and the intention required for murder; in the habeas matters it engages the lawfulness of the detention and the limits of the executive's power to detain. The matters reach the Federal Court where a point of law or of constitutional significance is in issue.

The overall profile is a criminal-prosecution practice spanning the trial and appellate courts, combining drug and homicide work with habeas corpus and detention matters. The reported reasons turn on the drug presumptions, the intention element in homicide, and the lawfulness of detention, rather than on commercial or private-law questions, marking a prosecution practice that reaches into the constitutional limits on the power to detain. The presence of habeas corpus matters alongside the drug and homicide work gives the practice a liberty dimension unusual for a prosecution profile weighted toward serious crime.
