regarding completion certificate in the agreement to sell Ex. PW1/1 or MOU Ex. PW1/2. Even proceeding from the premise that completion certificate was a statutory requirement, yet the plaintiff has no case to make out. It has been observed hereinabove that plaintiff was neither ready nor willing to perform his part of the contract. Therefore, when the plaintiff himself was not ready and willing, he cannot then shift the blame to the other side for the ultimate failure of the deal. Had the plaintiff in the very first place proved his readiness and willingness, then the question of compliance or otherwise of section 346, DMC Act would have come into the picture. Plaintiff being himself at fault cannot therefore point fingers at defendants no. 1 and 2 for their alleged non-compliance of section 346, Delhi Municipal Corporation Act. In other words, question of compliance or non-compliance of this provision and its effect on the outcome of the present suit would come into the picture only when the plaintiff proves in the first place that he was ready and willing to perform his part of the contract. Even assuming that there was non-compliance of this provision, yet the plaintiff cannot be held entitled to the relief of specific performance as sought for. It is the plaintiff's suit that would face an adverse outcome if he does not prove the existence of facts, which he asserts (section 101, Evidence Act). Plaintiff avers readiness and willingness on his part and therefore it is he who must prove it in terms of section 101, Evidence Act. Plaintiff cannot seek to prove his case in an indirect manner by urging that defendants' case has a certain deficiency or that there has been non-compliance of a certain legal provision on their part. Plaintiff cannot succeed on the basis of failure, if any, on the part of a defendant to prove his case and plaintiff must stand on its own legs. To put it in other words, a plaintiff must succeed on the basis and on the strength of his own case and not on the strength of deficiencies, if any, in defendant's case. He cannot raise the edifice of his case by highlighting the deficiencies/loopholes in defendants' case. In this regard, the following decisions can be referred to: Sankar Kumar v. Mohanlal Sharma, AIR 1998 Ori 117; Shiv Nandan Sachdeva (Sh.) v. Smt. Ruby, 2009 V (Delhi) 55; Umesh Bondre v. Wilfred Fernandes, AIR 2007 Bom 29; M.P. Narayan v. Sm. Sudhadevi, AIR 1986 Cal 256; State of West Bengal v. Subimal Kumar Mondal, AIR 1982 Cal
