None of the conditions in the notification is under challenge before the Tribunal. A corrigendum can only be issued to supplement the conditions laid down in the original notification, but the corrigendum cannot be issued contrary to the notification. The conditions in the notification itself are very clear that the district is the unit and the candidates can apply a district post either Local or Non-local basis and shall take examination in that district only. Suppose a person belonging to a particular district wants to write an examination in a different district, he can write the examination in the different district, but his case can be considered as a non-local at the place of writing the examination. Therefore, when the conditions laid down in the notification are very clear that the place of examination centre is the criteria for taking him as a local or non-local candidate, that condition has to be implemented strictly. No doubt, that condition in the notification runs contrary to the presidential order but, at the same time, when the notification itself is not under challenge, we cannot struck down the conditions, which contained in the notification, as illegal and arbitrary. There should be a factual foundation that some of the conditions laid down in the notification are contrary to the presidential order. Therefore, that issue cannot be decided in the absence of challenge.
