landlord and a tenant relating to the recovery of rent or possession of the premises the Small Causes Court acquires the jurisdiction not only to entertain that suit but also "to deal with any claim or question arising out of the Act or any of its provisions" which may properly be raised in such a suit. The plaintiffs in this suit claimed that the purported subletting by the first defendant to the second defendant was unlawful both because it was a breach of the terms of the tenancy and also because as the statutory tenant after the determination of the contractual tenancy the first defendant was not entitled to create a sub-tenancy and they questioned the validity of the second defendant's claim to any protection under the Act. The claim or question as to the respective rights of the plaintiffs and the second defendant thus raised in the plaint certainly arises out of the Act and the language of section 28 appears to be wide enough to cover the same. Apart from that section, under the ordinary law a decree for possession passed against a tenant in a suit for ejectment is binding on a person claiming title under or through that tenant and is executable against such person whether or not he was or was not a party to the suit. The non-joinder of such a person does not render the decree any the less binding on him. It is in this sense, therefore, that he is not a necessary party to an ejectment suit against the tenant. It is, however, recognised that such a person is, nevertheless, a proper party to the suit in order that the question whether the lease has been properly determined and the landlord plaintiff is entitled to recover possession of the premises may be decided in his presence so that he may have the opportunity to see that there is no collusion between the landlord and the tenant under or through whom he claims and to seek protection under the Act, if he is entitled to any. Such a person may be joined as a party to the suit from the beginning of the suit or at any later stage of the suit if the Court thinks fit to do so. The joinder of such a proper party cannot alter the character of the suit and does not make the suit any the less a suit between the landlord and the tenant or take it out of section 28 of the Act. To hold otherwise will be to encourage multiplicity of suits which will result in no end of inconvenience and confusion.
