"Application dismissed as withdraw," the bench said.
Kumar had moved the tribunal aggrieved over non-inclusion of his name among the three officers shortlisted by the Central Vigilance Commission (CVC) for being considered for the post of the next CBI Director.
Kumar, a 1976 batch IPS officer, in his application had questioned the procedure for picking the three officers and excluding his name for the top post in country's premier investigating agency.
The CVC-headed selection committee had cleared a panel of three senior IPS officers--Sinha, DG of National Investigation Agency S C Sinha (1975-batch IPS officer of Haryana cadre) and former Uttar Pradesh DG Atul (1976-batch IPS officer of UP cadre).
An official order had yesterday said Sinha has been appointed as CBI Director for a "period of two years from the date of assumption of office". He will take over from the present CBI Director A P Singh who is retiring on November 30.
