87.Subsections (1) to (5) set out that if without reasonable excuse a person remains on or enters premises in contravention of a closure order or notice or obstructs an authorised person who has entered the premises to secure it or carry out essential repairs, they will be guilty of an offence, which could result in a fine, or imprisonment or both. While subsection (2) – setting out that it is an offence to obstruct an authorised person – applies only to an authorised person, section 41 of the Police (Scotland) Act 1967 protects constables in a similar way.
