150.Subsection (1) applies subsections (3) and (4) where a person enters a contract to dispose of a chargeable interest and the disposal is completed by a conveyance.
151.Subsection (2) provides that a person is not seen as disposing of a chargeable interest just because it has entered into the contract to dispose of a chargeable interest where the contract provides for disposal to be completed by conveyance.
152.Subsection (3) provides that a contract substantially performed but not completed will, for this Part be considered as though the substantial performance of the contract was completion of the disposal which the contract had intended.
153.Subsection (4) provides that where subsection (3) applies and the contract is later completed through a conveyance, for the purposes of section 8, it is not deemed that completion effected disposal of a chargeable interest.
154.Subsection (5) sets out the effect of this Part where subsection (3) applies along with other conditions that deem the vendor to have re-acquired the interest referred to in subsection (1)(a).
155.Subsection (6) defines “the relevant time” for the purposes of subsection (5).
156.Subsection (7) provides that where subsection (3) applies and the contract is subsequently varied or partially rescinded so as to alter the chargeable interest to be disposed of (so that it is not the same chargeable interest provided for in the original contract), the variation is treated as effecting the reacquisition by the vendor (V) of the interest referred to in subsection (1)(a) and the substantial performance of the varied contract.
157.Subsection (8) applies subsection (7) if the parties proceed as if they had varied the contract in the way subsection (7) sets out, without actually having varied the contract, as if they had.
158.Subsection (9) provides further definitions for this section.
