Yes, you should file the statement of defence to the arbitrator, if necessary, with a request to condone the delay, if any, if the arbitration proceedings are still not over.
It may be pointed out that under the provisions of the Arbitration and Conciliation Act, the arbitral tribunal is not bound by the Civil Procedure Code and the Evidence Act. Parties are free to agree to the procedure to be adopted; failing which the arbitral tribunal has the freedom to conduct the proceedings in the manner deemed appropriate by it. Further, the Supreme Court has held that the principles of natural justice apply to such proceedings. This implies that a reasonable opportunity of being heard has to be given to each party.
Therefore, it you were prevented by a genuine reason from submitting your statement of defence in time and if the arbitration proceedings are still going on, you may submit your defence with a request to condone the delay, if any. The arbitral tribunal, as mentioned above, has sufficient powers to appropriately adopt a procedure that is just and fair in the circumstances of the case, and to comply with the principles of natural justice.
I may also point out that if an arbitral award is passed without hearing you, then under the provisions of Section 34 of the said Act, an application to set aside the arbitral award can be filed before the competent court, inter alia, on the grounds that a party was unable to present its case, or a party was under some incapacity, or the party was not given proper notice of the appointment of an arbitrator or of the arbitral proceedings.
Please note that Section 5 of the said Act forbids judicial intervention in arbitration matters except as provided under the Act. Therefore, it would be advisable to make use of whatever opportunity is available during the arbitration proceedings.
