Roll-over relief: compulsory acquisition of land: authority exercising or having compulsory powers
The phrase “an authority exercising or having compulsory powers” is defined by TCGA92/S243 (5) to include a person or body of persons:
- acquiring the land compulsorily, or
- who has been or could be authorised to acquire it compulsorily for the purposes for which it is acquired, or
- for whom another person or body of persons is or could be authorised to acquire it.
So it is not necessary that the land is acquired using compulsory purchase powers. It is only necessary that compulsory purchase powers are available to acquire the land for the purpose for which it is being acquired.
The decision of the First Tier Tribunal in Abdul Ahad v HMRC Commissioners  UKFTT353, contains a useful discussion of this definition.
