Respondent Conti ignored and failed to comply with three Resolutions issued by this Court repeatedly requiring him to file comment. This fact alone constitutes gross insubordination as would warrant disciplinary sanction by this Court. His resignation, sans any comment or explanation, only bolsters the charge against him and manifests his guilt for the offense complained of. Even after the non-acceptance of his resignation, he still did not bother to inquire as to the reason therefor or explain his side of the matter. By his complete and stubborn silence, he is deemed to waive his right to contest the factual findings and recommendations of the Investigating Judge and the Acting Court Administrator. [A.M. No. P-90-454. December 17, 1996]
