the same time, the Courts have also repeatedly remarked that the principles of natural justice are very flexible principles. They cannot be applied in any straight-jacket formula. It all depends upon the kind of functions performed and to the extent to which a person is likely to be affected. For this reason, certain exceptions to the aforesaid principles have been invoked under certain circumstances. For example, the Courts have held that it would be sufficient to allow a person to make a representation and oral hearing may not be necessary in all cases, though in some matters, depending upon the nature of the case, not only fullfledged oral hearing but even cross-examination of witnesses is treated as necessary concomitant of the principles of natural justice. Likewise, in service matters relating to major punishment by way of disciplinary action, the requirement is very strict and full-fledged opportunity is envisaged under the statutory rules as well. On the other hand, in those cases where there is an admission of charge, even when no such formal inquiry is held, the punishment based on such admission is upheld. It is for this reason, in certain circumstances, even post-decisional hearing is held to be permissible. Further, the Courts have held that under certain circumstances principles of natural justice may even be excluded by reason of diverse factors like time, place, the apprehended danger and so on."
