The arguments raised by the appellant were largely identical to those raised before the Judge in RA 70. First, he asserted that there was a bona fide defence that the respondent’s claim under the Guarantee was discharged if the underlying liability under the Facility Agreement between the respondent and LAPL had been set off. Second, the appellant submitted that there were several triable issues in respect of the dispute between the respondent and LAPL. He emphasised that the Guarantee involved secondary liability that was contingent on proof of primary liability under the Facility Agreement and the respondent could not claim against the appellant under the Guarantee since LAPL had validly exercised its right of set-off against the respondent (ie, the triable issue of whether there was a breach of the MOU), resulting in LAPL repaying the sums under the underlying agreement. Thus, the appellant argued he no longer owed any co-extensive liability under the Guarantee. Furthermore, the appellant contended that there was a triable issue as to whether the respondent had breached the MOU: given that the respondent rejected the appellant’s position as to the content of the obligations under the MOU and whether there was such request for performance, the respondent could not say that there was no dispute between the parties as to whether the respondent breached the MOU. Moreover, if the respondent did breach the MOU, the appellant submitted that whether LAPL had a valid right of set-off pursuant to Swiss law was put in issue.
