148.Subsection (1) defines "owner" for the purposes of liability for compensation. Before the appointed date of abolition, such a person will own the dominium utile and thereafter, by section 2(1) (consequences of abolition), will have simple ownership.
149.Subsection (2) makes it clear that where the land is held as common property, the former superior may recover all of the compensation from one of the co-owners. That co-owner would then have a right to recover the appropriate share from the other co-owners based on the size of their interest in the property.
