It simply states that the counterclaim for setting off is always admissible except only that the tribunal may find it appropriate to serve the counterclaim from the main claim lest a concurrent examination of counterclaim should excessively delay the judgment on the merits. 按其规定,要求抵消的反诉一般都应接受,除非仲裁庭认为同时审理反诉会过分耽误对事实的判决,因而认为把反诉同主诉分开比较恰当。
