My counter question on the postings is, do you think that the circulars/notifications issued prior to 1978 relevant even today or have they been revised as the time has progressed and most have become dormant?
A co-joinder on DCA is:
For a long time DCA was a part of ministry of heavy industries; then part of the law ministry; then part of the finance ministry. However, right until the year 2004, DCA was never thought of as an independent ministry and, rightly so, the main job of the DCA was the administration of the Companies Act along with some other enactments.
