A constable who suspects with reasonable cause that any person is committing or has committed an offence under Chapter 1 or 2 may enter any premises (other than premises used only as a private dwelling house) for the purpose of obtaining evidence of the offence.

A right to enter any premises conferred by subsection (1) may be exercised only at a reasonable time.

A sheriff may by warrant authorise a constable authorised to exercise the power conferred by subsection (1) to do so (if necessary using reasonable force) in accordance with the warrant.

A warrant may be granted under subsection (3) only if the sheriff is satisfied, by evidence on oath, that there are reasonable grounds for suspecting that an offence under Chapter 1 or 2 is or has been committed on the premises.
