15. So far as the claim that Vijay Kumar is not the owner of the property is concerned, I am of the view that Section 14(1)(e) not only applies to an owner but also to a landlord. Judicial precedents are in abundance to indicate that an eviction petitioner need not be required to show absolute ownership and it would be sufficient if he is able to show that he is more than the tenant. Vijay Kumar has shown multiple registered documents to claim ownership. A registered document always carries with it a presumption of genuinity. Only because the tenant is suddenly desirous of disputing such documents that too in collateral proceeding, the presumption will not vanish. The tenant himself has mentioned in these applications about several registered documents right from the year 1959. If we allow the tenant to doubt such registered documents mere on ipse dixit of the tenant (who was not concerned with those documents or their registration), we will be doubting the acts of several sub-registrars before whom those documents were registered. When official acts are deemed to have been performed properly, there would be a need of very strong case to raise doubt thereon. A mere bald claim of a person that too who has already lost upto Supreme Court, should not become the basis of any such doubt. Apart from the registered documents, there have been mutation in MCD records for tax purposes and this has been pleaded by the tenant himself in these applications. Now, the tenant wants to say that even such record is wrongly obtained. It appears that the tenant wishes that everyone and everything is wrong except his words. This cannot be encouraged at all.
