He said the formation of the committee is a "tactic" of the Centre to "evade" the issue and added the modalities can be decided even after conferring the status.
The Centre had on February 29 set up a committee, to be headed by Special Secretary (Internal Security) in the Home Ministry Mahesh Kumar Singla, to recommend the modalities for granting of ST status to six OBC communities in Assam.
The Chief Minister urged the Centre to accord the ST status to the six communities - Moran, Muttock, Tai Ahom, Koch Rajbongshi, Sootea and Tea Tribes - expeditiously shunning its "dilly-dally tactic".
"Had this power been given to us, we'd have conferred the ST status upon the six communities long back," Gogoi said.
