1st of January following the year in which the applications are invited. All service Rules are uniform on this point. Looking to the various dates on which different departments and different heads of administration may issue their advertisements for recruitment, a uniform cut off date has been fixed in respect of all such advertisements as 1st January of the year following. This is to make for certainty. Such a uniform date prescribed under all service Rules and Regulations makes it easier for the prospective candidates to understand their eligibility for applying for the post in question. Such a date is not so wide off the mark as to be construed as grossly unreasonable or arbitrary. The time gap between the advertisement and the cut off date is less than a year. It takes into account the fact that after the advertisement, time has to be allowed for receipt of applications, for their scrutiny, for calling candidates for interview, for preparing a panel of selected candidates and for actual appointment. The cut off date, therefore, cannot be considered as unreasonable. It was, however, strenuously urged before us that the only acceptable cut off date is the last date for receipt of applications under a given advertisement. Undoubtedly, this can be a possible cut off date. But there is no basis for urging that this is the only reasonable cut off date. Even such a date is liable to question in given circumstances. In the first place, making a cut off date dependent on the last date for receiving applications, makes it more subject to vagaries of the department concerned, making it dependant on the date when each department issues an advertisement, and the date which each department concerned fixes as the last date for receiving applications. A person who may fail on the wrong side of such a cut off date may well contend that the cut off date is unfair, since the advertisement could have been issued earlier: Or in the alternative that the cut off date could have been fixed later at the point of selection or appointment. Such an argument is always open, irrespective of the cut off date fixed and the manner in which it is fixed. That is by this court has said in the case of Parameshwaran Match Works (supra) and later cases that the cut off date is valid unless it is so capricious or whimsical as to be wholly unreasonable. To say that the only cut off date can be the last date for receiving applications, appears to be without any basis. In
