During arbitral proceedings, the parties may not always be able to collect all relevant documents and evidence from the outset. Certain evidence may only be discovered after the Statement of Claim or Statement of Defence has been submitted, or after the deadline prescribed by the Arbitral Tribunal. In such circumstances, will late-submitted documents and evidence still be considered?

The parties may still submit documents and evidence after the deadline; however, the Arbitral Tribunal is not automatically required to admit or consider such evidence. The consequences of late submission depend on the time of submission, the applicable Rules of Arbitration, the parties’ agreement, the directions of the Arbitral Tribunal, and the reasons for the delay.
1. Submission of evidence is both a right and an obligation of the parties
Under Article 46.1 of the 2010 Law on Commercial Arbitration (LCA), the parties have the right and obligation to provide evidence to the Arbitral Tribunal to establish the facts relevant to the matters in dispute.
Similarly, Article 19.1 of the MCAC Rules of Arbitration provides that the Arbitral Tribunal has the power to require the parties to provide evidence, and the parties are obliged to provide such evidence.
Arbitration law does not prescribe a single general deadline applicable to the submission of all documents and evidence. Depending on the particular dispute, the applicable deadline may be determined by the Rules of Arbitration, the parties’ agreement, or the procedural directions or decisions of the Arbitral Tribunal.
2. Submission of evidence after the deadline but before the conclusion of the final hearing
Where evidence is submitted after a deadline prescribed during the resolution of a dispute, the delay does not automatically render the documents or evidence inadmissible or devoid of evidentiary value. Nevertheless, the submitting party cannot assume that the Arbitral Tribunal will necessarily consider such documents or evidence.
The Arbitral Tribunal may generally take the following factors into account:
The consideration of late-submitted documents and evidence must also comply with the principle of equal treatment of the parties under Article 4.3 of the 2010 Law on Commercial Arbitration. Therefore, if such documents or evidence are admitted, the other party should be given a reasonable opportunity to access them and submit its response.
It is also necessary to distinguish between the supplementation of evidence and the amendment or supplementation of a Statement of Claim, Counterclaim, or Statement of Defence. Under Article 14.2 of the MCAC Rules of Arbitration, the parties may amend or supplement these submissions before the conclusion of the final hearing. However, the Arbitral Tribunal may refuse to accept such amendments or supplements if they may be abused to obstruct the proceedings, delay the issuance of the Arbitral Award, or exceed the scope of the Arbitration Agreement.
3. Submission of evidence after the conclusion of the final hearing
Article 25.4 of the MCAC Rules of Arbitration provides that, at a hearing for the resolution of the dispute, where the Arbitral Tribunal determines that the parties have no further relevant documents or evidence to submit, it shall declare that hearing to be the final hearing. After the conclusion of the final hearing, the Arbitral Tribunal is under no obligation to consider any additional documents or evidence unless otherwise agreed by the parties.
Accordingly, after this point, a party may still submit additional documents or evidence, but the Arbitral Tribunal is not obliged to consider them unless the parties to the dispute have agreed otherwise. Where the parties agree to permit the submission of additional evidence, its admission and consideration must still safeguard the other party’s right to access and respond to such evidence.
4. What should businesses do when documents or evidence are submitted late?
To minimise the risk that documents or evidence will not be considered, businesses should:
Where a business receives evidence submitted late by the other party, it should promptly state whether it accepts or objects to the admission of that evidence. If the Arbitral Tribunal decides to consider the evidence, the business should also request a reasonable period to examine it and submit its response.
Conclusion
The submission of documents and evidence after the deadline does not necessarily mean that they will automatically be excluded from consideration. However, after the conclusion of the final hearing, the Arbitral Tribunal is under no obligation to consider any additional documents or evidence unless otherwise agreed by the parties. The parties should therefore comply with the applicable submission deadlines and promptly provide an explanation whenever a late submission occurs.

Courts and arbitration are both methods of dispute resolution and act as adjudicative forums for the parties to a dispute. The outcomes of dispute resolution by a court or by arbitration have equivalent legal effect. Some basic similarities are as follows:
Decision No. 131/2024/QĐ-PQTT dated June 27, 2024 of the People’s Court of Ho Chi Minh City is a notable practical case concerning a request to set aside an arbitral award in relation to the determination of late-payment interest.[1]
