The Central Administrative Tribunal (CAT), Principal Bench, New Delhi, has ruled that disciplinary proceedings against IRS officer Sameer Wankhede are legally untenable, as the charge memorandum issued to him relied on material from a preliminary enquiry whose use had already been prohibited by judicial orders, news agency ANI reported.

The tribunal held that the authorities acted in violation of settled legal principles and binding court directions by proceeding on the basis of such material.
