Subsection (2) applies where any authority of a Convention country (other than the United Kingdom) or of the Channel Islands, the Isle of Man or any British overseas territory has power under the law of that country or territory—
to authorise, or review the authorisation of, an adoption order made in that country or territory, or
to give or review a decision revoking or annulling such an order or a Convention adoption.
If the authority makes a determination in the exercise of that power, the determination is to have effect for the purpose of effecting, confirming or terminating the adoption in question or, as the case may be, confirming its termination.
Subsection (2) is subject to section 89 and to any subsequent determination having effect under that subsection.
