[1] Pursuant to s 5 of the Reciprocal Enforcement of Judgments Act 1958 [Act 99] ("the Act"), the respondent successfully applied, vide encl 10, to set aside an earlier order of the High Court made on 29 January 2018. By that earlier order, a judgment pronounced by the High Court of Singapore in Case No: HC/JUD 742/2017 on 15 December 2017 was registered pursuant to s 4 of the Act. This appeal is in respect of that decision made under s 5 of the Act.

[2] After hearing extensive submissions from the parties, both oral and written, and upon careful consideration of those submissions, the grounds of decision and the records of appeal, and the applicable law, we were unanimous in our decision that the learned judge had plainly erred in granting the order sought. The appeal was consequently allowed with costs, and the decision of the High Court dated 4 June 2018 was thereby set aside. These are our reasons in full.
