In this context, Section 8 of the Arbitration and Conciliation Act is very clear which stipulates that if a party wants to refer the matter before the Arbitrator in terms of agreement clause, then he will have to do the same not later than the date of submitting his first statement. Section 4 stipulates that when a party who knows that a requirement under the arbitration agreement has not been complied with, then he deemed to have been waived his right in terms of the agreement. In this context, reliance has also been placed in a judgment reported in 2020 SCC OnLine Cal 1658 (Lindsay International Private Limited & Ors. v. Laxmi Niwas Mittal & Ors.) wherein it was held that once a suit is filed by a party to an arbitration agreement the other party must at the earliest stage in the proceedings or at the time when the first statement of defence to the plaintiffs claims, file an application under Section 8, it is only then, that the Court may refer the parties to arbitration after applying the tests in the Booz Allen case (2011) 5 SCC 532.
