That is sufficienctly certain which can be made certain.
Where no date is fixed in the agreement and the document is loosely worded, the maxim “certum est quod certum reddi potest” is not to be involved . If suit is filed within four months from the date of knowledge the second limb of Article 54 applies. [AIR 1985 MP 39]. In a suit for possession and in the alternative for specific performance of contract of renewal of lessee put on 31-12-1967 and new lessee put in possession on 1-1-1968; the plaintiff waiting till 15-12-1970 for filing suit; it was held that there was no justification for delay even if the plaintiff was seeking relief before the departmental authorities. [(1979) 48 Cut LT 294]. [Article 54, Limitation Act, 1963].
The maxim was held to be not applicable in the facts and circumstances of the case. [Vimlesh Kumari Kulshrestha v. Sambhajirao, (2008) 5 SCC 58].
