Commentary on Sections Part 2: Enforcement Section 8: Search and seizure
12.Section 8 confers powers of search and seizure without a warrant where a constable reasonably suspects that a person is committing or has committed an offence under the Act.  Subsections (2) and (3) authorise the constable to stop and search that person and any vehicle, animal or other thing in his possession or control, while subsection (4) authorises the constable to seize and detain any vehicle, animal or other thing if he reasonably believes that it may be used as evidence in criminal proceedings for an offence under the Act or may be subject to a forfeiture order under section 9.
13.Subsection (5) provides that for the purpose of exercising these powers of search and seizure a constable may enter land, premises other than a dwelling or a vehicle.
