11. Taking advantage of non supply of list of documents and list of witnesses, the counsel for the petitioner, Sri J. Sudheer, contended that it is violation of principles of natural justice. The 3rd respondent after conducting necessary enquiry, called upon the petitioner to submit his written submission and accordingly by letter dated 11.02.1998 the defence representative submitted written submission and similarly the Management Representative, S. Sridhara Rao submitted a written submission by letter dated 12.02.1998. On considering the material on record including the written submissions, the 3rd respondent found the petitioner guilty of grave misconduct. While recording the findings, the enquiry officer relied on complaint dated 22.09.1998 of M/s. Aar Bee enterprises, Hyderabad and office note dated 23.09.1998 and letter dated 23.09.1998 addressed to the General Manager (personal) of Zonal Officer, Hyderabad and evidence of M.Ws.1 and 2, S.K. Sahay and K. Raghavendra Rao. In normal course of events, along with the charge sheet, list of documents proposed to be relied on by the Management have to be furnished so as to enable the employee to submit his written explanation for the charge memo and list of witnesses proposed to be examined on behalf of the Management. He failed to comply such requirement. It amounts to violation of principles of natural justice. Having maintained silence for a long period, till completion of enquiry, and on appeal against enquiry officer’s report, the petitioner is not entitled to raise such plea for the first time in the writ petition.
