152.Section 44 reflects the position that applies in section 140(8) of the Roads (Scotland) Act 1984 by requiring a warrant to use, if necessary, reasonable force to enter land. Subsection (1) sets out the terms of warrant and subsection (2) provides the test that the sheriff or justice of the peace must apply prior to granting a warrant. Subsection (3) provides that a warrant cannot authorise the use of force against individuals. Subsection (4) provides for the extent of the life of the warrant which will expire either when the purpose for which it is granted is no longer required or, if earlier, the time period specified in the warrant has expired.
