Umbrella Clause - Arbitration Clause Incorporation by reference

The Supreme Court accepted the proposition that even where a contract between two parties does not contain a provision for arbitration, an arbitration clause contained in an independent document will be incorporated into the contract between the parties by reference to an independent document in the contract if the reference is such to make thearbitration clause in the independent document a part of the contract. However, based on the facts of the case, it was held that there was no incorporation of the arbitration clause  r because: (i) the parties never intended to incorporate the same into the subcontract; and (ii) the entire arbitration agreement contained in the main contract was tailor-made to meet the requirements of the contract between X and Y, where Z did not have any role.
