shape of an agreement agreeing to carry out the work confirming advance of Rs.1,000/- received for the work. This solitary instance of work would not establish joint business carried on by both of them and it may be that this particular work was undertaken by them together. Similarly, Ex.A11 is a statement of work carried out with endorsement that it is checked and cleared by the owner on 20.08.1972 and is signed by the defendant on that date i.e. 20.08.1972 and also an abstract of bill dated 26.07.1972 for constructions of superstructure relating to a house of one Thamboo Swamy and it appears to be just measurement details of the work. Similarly, Ex.A12 is the schedule of rates giving item-wise quotations for same work, which is said to be signed by the defendant. The statement of work and abstract of the four items is the only evidence produced by the plaintiff to claim that there is a joint business by both of them. There is no evidence of existence of any joint family business inherited by the plaintiff and the defendant from their father nor there is any evidence to establish existence of any nucleus available to either plaintiff or the defendant. It is, therefore, apparent that both of them have worked by using their individual skills and have carried out different works and earned monies. The slender evidence under Exs.A9 to A12, therefore, is not sufficient to hold a presumption in favour of plaintiff that the plaintiff and the defendant were carrying on joint business. As mentioned above, the plaintiff could have produced enough evidence as the period of more than two decades elapsed before filing of the present suit and there could have been numerous instances of work and earnings, if really, both of them were jointly carrying on the business.
