Joint trial arises when the rival parties claim independent action, but based on same cause of action; for enforcement of rights or obligations springing out of that cause of action

In State Bank of India V. Ranjan Chemicals Ltd. & Anr., (2007) 1 SCC 97, the Supreme Court considered the issue of consolidation of suits and observed that the question of joint trial arises when the rival parties claim independent action, but based on same cause of action; for enforcement of rights or obligations springing out of that cause of action. The joint trial should be permitted if it appears that some common question of law or fact arises in both the proceedings or that the right to relief claimed in them are in respect of or arise out of the same transaction or series of transactions or that for some other reason it is desirable to make an order of joint trial. In such a situation, the joint trial will save the expenses of two attendances by the counsel and witnesses and the trial Judge will be enabled to try two actions at the same time and take common evidence in respect of both the claims. It is not necessary that all questions or issues that arise should be common to both actions before a joint trial can be ordered. It would be sufficient if some of the issues are common and some of the evidence to be led in is also common.
The joint trial may avoid separate overlapping evidence being taken in the two cases and
it will be more convenient to try them together in the interests of parties and in the interest of an effiective trial of the causes. This power inhears in the Court as an inherent power.
