In which of the following cases, the Supreme Court held that registered documents have better evidentiary value over non registered documents?

In Maya Devi v Lalta Prasad, the court observed “there can be no gain saying that when the probative value of documents is to be assessed, specially those dealing with the creation of any interest in property or its transfer, of a value exceeding Rs.100/-, obviously documents which have been duly registered regardless of whether or not that was legally mandatory, would score over others.” In Bhoop Singh vs. Ram Singh Majar, it was held that Decree passed in suit whereby conferring ownership, based upon pre-existing right, does not require registration under Sec 17 of Registration Act
