3. The short facts, which led to the filing of the present writ application is that vide Office Order dated 07.02.1972, as contained in Annexure-1, the writ petitioner came to be appointed as Aakasmik Bhritya/Casual Peon and he joined in the River Valley Scheme, Secretariat, Patna on 07.02.1972 itself.

It is vehemently contended that before making deduction of the amount paid to him, earlier granted to him by way of benefit of the one of the two ACPs., was actuated without the petitioner being heard and any show-cause to be served upon him and, in fact, in complete defiance of the principles of the natural justice.
