Judgement TRIVEDI, J. :- The following question on reference by a learned Single Judge of this Court has come for decision before this Full Bench. "Is the plaintiffs suit (No. 16 of 1973) maintainable having regard to the provision of Order 2, Rule 2 of the Civil Procedure Code." 2. Atma Ram Srivastava is the landlord of a certain house let out by him to Sardar Balbir Singh on a monthly rent of Rs. 20/-. The defendant being in arrears of rent for April and May, 1968, his tenancy was terminated by a notice dated 22-5-1968 served on 4-7-1968 by which the defendant was asked to vacate the premises on the expiry of three months from service of notice and payment of two months arrears of rent was demanded. The tenant neither paid the rent nor vacated the premises. On 28-5-1969 Atma Ram Srivastava, opposite party in this revision, filed a suit against him in the Court of the Munsif South, Lucknow (Regular Suit No. 354 of 1969). In that suit he claimed a decree for arrears of rent and mesne profits without claiming ejectment of the defendant Sardar Balbir Singh. In Para. 5 of the plaint the plaintiff specifically reserved his right to file a suit for ejectment of the tenant and on 23-7-1969 he moved an application for leave of the court for filing a suit for ejectment subsequently. On 24-7-1969 the court granted this permission to file another suit subsequently for ejectment of the applicant-tenant. 3. While the earlier suit was pending the landlord-opposite party filed a second suit on 3-2-1970 against the applicant in the Court of Munsif South, Lucknow, (Suit No. 90 of 1970) praying for ejectment and mesne profits which arose subsequent to the filing of the first suit. The plaint of the suit was returned and was eventually filed in the court of the District Judge, Lucknow, as the Munsif lacked pecuniary jurisdiction and was registered there as Suit No. 16 of 1973. In the second suit the landlord claimed a decree for ejectment and mesne profits which accrued subsequent to the earlier suit. Suit No. 16 of 1973 is now pending in the court of the Additional District Judge, Lucknow. In the second suit the landlord claimed a decree for ejectment and mesne profits which accrued subsequent to the earlier suit. Suit No. 16 of 1973 is now pending in the court of the Additional District Judge, Lucknow. In the second suit the defendant raised an objection that the plaintiff not having included the relief of ejectment from the house in the first suit, the subsequent suit was barred by Order 2, Rule 2 of the Civil Procedure Code. The Additional District Judge decided this objection as a preliminary point and held that the cause of action for a suit for possession is different from the cause of action for a suit for arrears of rent and mesne profits on the basis of the terms of Order 2, Rule 4 of the Civil Procedure Code which permitted the plaintiff to combine a claim for mesne profits with a claim for ejectment. The Additional District Judge had further held that quite apart from this the second suit was maintainable and the bar of Order 2, Rule 2 did not operate as the plaintiff had in the first suit reserved his right to file a suit for ejectment later and as the court had passed an order granting him permission to do so. Against the judgment of the Additional District Judge the defendant filed a revision in this Court which coming before the learned single Judge the referring order was made. 4. Order 2, Rule 2 of the Civil Procedure Code is as follows:- "(1) Every suit shall include the whole of the claim which the plaintiff is entitled to make in respect of the cause of action; but a plaintiff may relinquish any portion of his clam in order to bring the suit within the jurisdiction of any Court. (2) Where a plaintiff omits to sue in respect of, or intentionally relinquishes, any portion of his claim, he shall not afterwards, sue in respect of the portion so omitted or relinquished. (3) A person entitled to more than one relief in respect of the same cause of action may sue for all or any of such reliefs; but if he omits, except with the leave of the court, to sue for all such reliefs, he shall not afterwards sue for any relief so omitted." 5. (3) A person entitled to more than one relief in respect of the same cause of action may sue for all or any of such reliefs; but if he omits, except with the leave of the court, to sue for all such reliefs, he shall not afterwards sue for any relief so omitted." 5. Order 2, Rule 3 permits the joinder of several causes of action in the same suit by the plaintiff against the defendant or defendants, Order 2, Rule 4 says: "(4) No cause of action shall, unless with the leave of the Court, be joined with a suit for the recovery of immovable property, except- (a) claims for mesne profits or arrears of rent in respect of the property claimed or any part thereof ; (b) claims for damages for breach of any contract under which the property or any part thereof is held; and (c) claims in whic
