In February 2019, the Law Reform Committee of the Singapore Law Academy recently published a report on some of the cost issues in arbitration. The report recommended that steps be taken to provide the courts with better cost advice when addressing the issue of arbitration costs. Although the recommendations have not yet been implemented, the recommendations and the subcommittee`s report may reflect a greater focus on managing the cost of arbitration proceedings in Singapore. In the event of a dispute over the interpretation of the arbitration agreement and where a party intends to rely on pre-contract negotiations to support its interpretation of the arbitration agreement, such evidence should be presented to the Tribunal (e.g. B as part of the provisional establishment of the Tribunal`s jurisdiction), instead of presenting such evidence only when the dispute is brought before the supervisory court. This is because the restrictions applied by many common courts to the admission of evidence for pre-contract negotiations (or evidence of contract conduct) generally do not apply to arbitration proceedings15. Once the evidence is admitted before the Tribunal, it would be part of the minutes of the proceedings and would likely be reviewed by a supervisory tribunal that would review the Tribunal`s decision without necessarily having to meet the Court`s criteria for admissible pre-contract hearings. In the BNA`s opinion, the applicant (who wished to rely on evidence of pre-contract negotiations) did not present the evidence to the Tribunal and only sought to introduce it into sworn assurances filed in the High Court litigation. The Court refused to admit the evidence because it did not respect the limited exceptions to the Parol rule, but found that the result could have been quite different if the applicant had presented the evidence before the Tribunal.16 First, the law of the main contract applies to the terms of the main contract and to the validity, interpretation and compliance of those conditions that are not those of the separate arbitration agreement, and to the validity, interpretation and compliance of these separate arbitration conditions.
