paper. The reasoning of the first appellate court in paragraph 29 of its judgment was not addressed by the High Court. In fact, the High Court, in one line, on a flimsy defense of use of a signed blank paper, observed that genuineness of Exb. A-2 is not proved. In our view, the High Court fell in error here. While exercising powers under Section 100 CPC, it ought not to have interfered with the finding of fact returned by the first appellate court on this aspect; more so, when the first appellate court had drawn its conclusion after appreciating the evidence available on record as also the circumstance that signature(s)/thumbmark(s) appearing on the document (Exb.A2) were not disputed.

The test is that the person claiming performance must satisfy conscience of the court that he has treated the contract subsisting with
