Hon’ble NCLAT held that: (i) The Adjudicating Authority cannot be faulted for having exercised caution in not taking any informed decision on the issue of whether WhatsApp messages evidenced pre-existing disputes by merely relying on the credibility of these WhatsApp messages. (ii) Merely because a meeting was held between the two parties to overcome the shortcomings in the meeting the obligations of supply and installation of pump-sets cannot be taken to imply that all disputes between the parties had subsided without the parties being at ad idem on whether the obligations stood discharged on a mutually satisfactory basis.
