Arbitrator observed that Clause 32.6 of the GCC clearly provides that payment of the final bill should be made within 30 days but despite the same erred in holding that since clauses 32.8 & 57 of the GCC empowers the Respondent Company to withhold the payment and since the Respondent Company already put to notice the Petitioner Company of the alleged deficiencies vide email dated 17.6.2020, therefore Claim No. 1 & Claim No. 7 of the Petitioner company is not maintainable. It is submitted that the Respondent Company raised Counter Claim No. 1 on account of refund of expense incurred by them qua alleged defective works as mentioned in email dated 17.6.2020.
