Section 40: Further provision about search warrants
Subsection (1) allows persons applying for search warrants to do so without informing those persons who might be affected by it (for example, the owner or occupier of the premises or the owner of the substances in question) to avoid forewarning such a person of the impending search thereby affording an opportunity to remove or otherwise hide the psychoactive substances or other evidence of an offence.paragraph 1(2)paragraph 1(3)
	Subsection (4) enables a search warrant to be executed by any relevant enforcement officer and not just the officer who applied for the warrant. If the search warrant so provides, subsection (5) enables authorised persons to accompany a relevant enforcement officer when executing a warrant. Such a person, for example, a Police Community Support Officer, has the same powers as those conferred on the relevant enforcement officer (subsection (6)).
	Subsection (7) gives effect to Schedule 3 which makes further provision about applications for and the execution of search warrants in England and Wales and Northern Ireland. Scotland has similar provisions in its common law. Failure to comply with the requirements in Part 2 of Schedule 3 in respect of the execution of warrants in these jurisdictions would render the entry and search of premises unlawful (subsection (8)).
