FRANCESCO MAZZAGATTI v ALLIANCE PETROCHEMICAL INVESTMENT (SINGAPORE) PTE. LTD.

Facts

Alliance Petrochemical Investment (Singapore) Pte Ltd suspected that its former director, Mr Francesco Mazzagatti, had siphoned large sums from it and from a subsidiary he had allegedly set up without the other directors' approval, Alliance Petrochemical Trading LLC, which had since been dissolved. Its only record was a 70-page ledger. In HC/OA 740/2023 Alliance obtained a pre-action discovery order (HC/ORC 3067/2024) requiring him to produce documents relating to the ledger transactions. He filed an affidavit saying he had none of them in his possession or control. Alliance obtained permission and began committal proceedings against him in HC/SUM 195/2025 for breach of the order.

Alliance had meanwhile sued him in England and obtained further documents there. On 17 March 2025, before he filed his reply affidavit in the committal proceedings, Alliance applied in HC/SUM 711/2025 for permission to file a further affidavit exhibiting five categories of documents. A High Court judge allowed four of them. Mr Mazzagatti applied in CA/OA 14/2025 for permission to appeal to the Court of Appeal, arguing only that the judge had made a prima facie error.

Issues

1. Whether the court has power to allow a committal applicant to file a further affidavit in committal proceedings under the Rules of Court 2021.
2. Whether the Ladd v Marshall test governs a request to file a further affidavit in committal proceedings not yet heard on the merits.

Holding

The Court of Appeal declined permission to appeal and dismissed the application on 21 July 2025 with costs fixed at $8,000 (all-in) payable to Alliance, giving these grounds later. The judge had made no prima facie error.

Reasoning

On the power question, the applicant argued that O 23 of the Rules of Court 2021 had dropped the old express permission for a committal applicant to rely on new grounds, and that grounds and evidence could no longer be separated now that a single affidavit carries both. The court accepted that O 23 had no such provision but held that it did not matter. Alliance was not raising a fresh ground; it was adding evidence for the same alleged breach of the discovery order, and the distinction between grounds and supporting evidence remained valid, as Summit Holdings Ltd and another v Business Software Alliance [1999] 2 SLR(R) 592 showed. Since O 23 is silent, the court's general power under O 3 r 2(2) to do what justice requires, consistent with the Ideals, supplied the power. The one-round rule in O 3 r 5(6) did not apply because the application was filed before the reply affidavit, which came on 27 March 2025.

The court listed non-exhaustive factors for such requests: why the material could not have been in the first affidavit, its relevance, promptness and undue procedural prejudice. The documents had become available only after the supporting affidavit was filed, relevance called for a light-touch assessment, and any prejudice could be met by a reply affidavit or costs. Given the quasi-criminal nature of committal, it was in the applicant's interest to know the full case against him.

On the second issue, the court agreed that the Ladd v Marshall test applies only to fresh evidence on appeal, where it protects finality after a hearing on the merits. The committal application had not been heard, so the test did not apply in full or in an attenuated form.
