154.Section 106 of the Title Conditions (Scotland) Act 2003 (asp 9) provides for the extinguishment of real burdens and servitudes etc. on the permanent compulsory acquisition of land but not where the occupation is temporary. To ensure that the Forth Crossing works are not compromised by existing servitudes, real burdens or development management schemes section 46 provides that these rights are unenforceable or disapplied in respect of land under section 37 or 39 for the period of possession. A definition is provided within section 46 for the period of possession over which servitudes, burdens or development management are unenforceable or disapplied.
