knowledge on the subject of relationship between the plaintiff and Ram Piari, and secondly because what section 50 made relevant was not mere opinion but opinion "expressed by conduct" of persons who as members of the family or other- wise, had special means of knowledge. It seems to us that the question as to how far the evidence of those particular witnesses is relevant under section 50 is academic, because it is well-settled that continuous cohabitation for a number of years may raise the presumption of marriage. In the present case, it seems clear that the plaintiff and Ram Piari lived and were treated as husband and wife for a number of years, and, in the absence of any material pointing to the contrary conclusion a presumption might have been drawn that they were lawfully married. But the presumption which may be drawn from long cohabitation is rebuttable, and if there are circumstances which weaken or destroy that presumption, the court cannot ignore them. We agree with the learned Judges of the High Court that in the present case, such circumstances are not wanting, and their cumulative effect warrants the conclusion that the plaintiff has failed to prove the factum of his marriage with Ram Piari. In the first place, the plaintiff has not examined any of his near relations such as his brother, or collaterals living in Ajnoha, or any co-villagers, whose presence at the marriage would have been far more probable than the presence of the witnesses examined by him. He has also not examined any of the witnesses residing in or round about Holta estate in spite of the fact that his own case is that the marriage was celebrated with great pomp and show. It. was suggested in the courts below that since defendant No. 2 is an influen- tial person, no local witnesses would be available to sup- port the plaintiff's case, but the High Court has very fully dealt with this aspect and pointed out firstly that Raj Kumari had litigation with a number of persons belonging to Palampur and such persons would not be under her influence, and secondly that no gold reason has been shown why Raj Kumari, who is alleged to have brought about the marriage between the plaintiff and Ram Hari, should take a completely hostile attitude towards him. Then again, neither the parents nor any of the relations of Ram Piari have been examined to support the plaintiff. On the other hand, Ram Hari's own mother, Ganga, has deposed that the former was never married to the plaintiff, and the statement made by Ram Piari in her will, which is a very valuable piece of evidence, is to the same effect. It is also in- credible that in spite of the love which Ram Piari is said to have had for the plaintiff, she left him and went away to live with Raj Kumari, and that during the long period when Ram Piari was away, the plaintiff should never have visited her or made enquiries about her and his alleged daughter, Parvin Kumari. This is all the more strange, since it is stated by the plaintiff that Ram Piari continued to love him and that she and Raj Kumari inwardly hated each other. Parvin Kumari says in her deposition that she had never seen her father and that when she reached the age of discretion she found herself living at Palampur. The conduct of the plaintiff in showing such complete indifference to his wife and daughter as is disclosed in his evi- dence is most unnatural, and no less unnatural is his con- duct in instituting a suit to deprive her of properties which had come
