The Hon’ble Supreme Court recently in Cuddalore Powergen Corporation Ltd v. M/s Chemplast Cuddalore Vinyls Limited and Anr [2025] 2 S.C.R. 123 : 2025 INSC 73, while adjudicating the rejection of suit under Order II Rule 2, categorically held that it does not operate as a bar when the subsequent suit is based on a cause of action different from that on which the first suit was based. It further held that the object of both the Rules 1 and 2 of Order II is to prevent the multiplicity of suits. Order II Rule 2 is founded on the principle that a person should not be vexed twice for one and the same cause. It is a rule which is directed against two evils i.e., the splitting up of claims and the splitting up of remedies. What Order II Rule 2 requires is the inclusion of the whole claim arising in respect of one and the same cause of action, in one suit. However, this must not be misunderstood to mean that every suit shall include every claim or every cause of action which the plaintiff may have against the defendant. Therefore, where the causes of action are different in the two suits, Order II Rule 2 would have no application.
The Court summarized the following principles underlying Order II Rule 2:
i. The object of Order II Rule 2 is to prevent the multiplicity of suits and the provision is founded on the principle that a person shall not be vexed twice for one and the same cause.
ii. The mandate of Order II Rule 2 is the inclusion of the whole claim arising in respect of one and the same cause of action, in one suit. It must not be misunderstood to mean that all the different causes of action arising from the same transaction must be included in a single suit.
iii. Several definitions have been given to the phrase “cause of action” and it can safely be said to mean – “every fact which would be necessary for the plaintiff to prove, if traversed, in order to support his right to the judgment of the Court”. Such a cause of action has no relation whatsoever to the defence that may be set up by the defendant, nor does it depend upon the character of the relief which is prayed for by the plaintiff but refers to the media upon which the plaintiff asks the Court to arrive at a conclusion in his favour.
iv. Similarly, several tests have been laid out to determine the applicability of Order II Rule 2 to a suit. While it is acknowledged that the same heavily depends on the particular facts and circumstances of each case, it can be said that a correct and reliable test is to determine whether the claim in the new suit is in fact founded upon a cause of action distinct from that which was the foundation of the former suit. Additionally, if the evidence required to support the claims is different, then the causes of action can also be considered to be different. Furthermore, it is necessary for the causes of action in the two suits to be identical in substance and not merely technically identical.
v. The defendant who takes shelter under the bar imposed by Order II Rule 2(3) must establish that (a) the second suit was in respect of the same cause of action as that on which the previous suit was based; (b) in respect of that cause of action, the plaintiff was entitled to more than one relief; and (c) being thus entitled to more than one relief, the plaintiff, without any leave obtained from the Court, omitted to sue for the relief for which the second suit had been filed.
vi. The defendant must also have produced the earlier plaint in evidence in order to establish that there is an identity in the causes of action between both the suits and that there was a deliberate relinquishment of a larger relief on the part of the plaintiff.
vii. Since the plea is a technical bar, it has to be established satisfactorily and cannot be presumed merely on the basis of inferential reasoning.
