“9. On the ground of estoppel and the conduct of the appellants in getting their earlier application made under Section 34 of the 1940 Act dismissed as not pressed that the applications under Section 8 of the 1996 Act were not countenanced by the High Court. The fact that the earlier application under the 1940 Act was got dismissed as not pressed in the teeth of the repeal of the said Act cannot, in our view, constitute any legal impediment for having recourse to and avail of the avenues thrown open to parties under the 1996 Act. Similarly, having regard to the distinct purposes, scope and object of the respective provisions of law in these two Acts, the plea of estoppel can have no application to deprive the appellants of the legitimate right to invoke an all comprehensive provision of mandatory character like Section 8 of the 1996 Act to have the matter relating to the disputes referred to arbitration, in terms of the arbitration agreement.”
