Fact of the case: I was Senior Manager in Central Bank of India.On 14/06/2013 the charge-sheet was served to me.I was not provided with defence representative but asked to search myself from the working officers of the Bank in terms of Regulation 6 (7). Regulation 6 (7)-The officer employee may take the assistance of any other officer employee but may not engage a legal practitioner for the purpose, unless the Presenting Officer appointed by the Disciplinary Authority is a legal practitioner or the Disciplinary Authority having regard to the circumstances of the case, so permits." Note: The officer employee shall not take the assistance of any other officer employee who has two pending disciplinary cases on hand in which he has given assistance . Thereafter, the I tried my level best to procure a competent Defence Representative (DR) to defend/assist/represent/help me in the departmental inquiry, but despite my best efforts I could not procure the same, as the fear psychosis, at the relevant time, was built in the mind of my co-Officer/s, that, if any of them will defend/assist/represent/help me, such a person would be harassed and victimized by the management. It is pertinent to mention, when ,despite my best efforts, I could not procure a competent DR to defend/assist/represent/help me in the departmental inquiry proceedings,I wrote several letter/s to Disciplinary Authority and inter alia requested on various genuine and legitimate grounds including facts and circumstances of the case: a).

To remove the stipulation contained in the suspension order dated [deleted], that I cannot leave the station without permission in writing from the Management, so as to enable me to search for a Competent DR for my defence. f).
