Part 4 makes provision for the closure of premises associated with significant and persistent disorder or significant, persistent and serious nuisance to members of the public. A closure notice will only be served on a premises once authorised by a senior police officer. That senior officer will then apply to the sheriff for a closure order, which will prohibit all access to the premises for a specified period (up to a maximum of 6 months, including extension). Failure to comply with a closure order will be a criminal offence.
