Rule 6 of the Posts and Telegraphs (Linemen/Sub-Inspectors/Line Inspectors) Recruitment Rules of 1969 is titled “Power to relax.” It reads: “Where the Central Government is of opinion that it is necessary or expedient so to do, it may, by order, for reasons to be recorded in writing, relax any of the provisions of these rules with respect to any class or category of persons/post.”
The same clause appears, almost word for word, in rules of 2019 for the National Financial Reporting Authority.
