“Government must be satisfied, not subjectively but objectively, that any rule or regulation affecting the conditions of service of a member of the All India Services causes undue hardship, then the iniquitous consequence thereof may be relieved against by relaxation of the concerned Rule or Regulation. There must be undue hardship and, further the relaxation must promote the dealing with the case “in a just and equitable manner”. These are perfectly sensible guidelines. What is more, there is implicit in the Rule, the compliance with natural justice so that nobody may be adversely affected even by administrative action without a hearing. We are unable to see anything unreasonable, capricious or deprivatory of the rights of anyone in this residuary power vested in the Central Government. Indeed, the present case is an excellent illustration of the proper exercise of the power. We are, therefore, satisfied that the Central Government was right in invoking its power to relax and regularize the spell of officiation, which was impugned as irregular or illegal. The consequence inevitably follows that the officer Ahluwalia was rightly assigned 1961 as the year of allotment.”
