establish that such arbitration agreement related to, or is applicable to, the suit transaction/contract. The parties may enter into different contracts at different points of time or may enter into a series of unrelated transactions. It is possible that in regard to some, they may provide for arbitration and in regard to others, may not provide for arbitration. Obviously, the existence of an arbitration agreement with reference to some other transaction/contract to which plaintiff was or is a party, unconnected with the transaction or contracts to which a suit relates, cannot be considered as existence of an 'arbitration agreement' in regard to the suit transactions/contracts. When Sections 7 and 8 of the Act refer to the existence of an arbitration agreement between the parties, they necessarily refer to an arbitration agreement in regard to the current dispute between the parties or the subject matter of the suit. It is fundamental that a provision for arbitration, to constitute an arbitration agreement for the purposes of Sections 7 and 8 of the Act, should satisfy two conditions. Firstly, it should be between the parties to the dispute. Secondly, it should relate to or applicable to the dispute.”
