The Calcutta High Court on Friday asked the Gorkha Janmukti Morcha (GJM) representatives to appear on June 23.
The GJM has been leading a violent agitation in Darjeeling against mandatory teaching of Bengali in government schools.
Principal Secretary Sanjay Mitra has been asked to submit the report within two days.
Meanwhile, violence continues to erupt in Darjeeling where state transport has been badly hit by the strike called by the GJM.
Police on Thursday recovered a cache of arms, arrows and cash during raids conducted at various GJM locations.
The Ministry of Home Affairs (MHA) is monitoring the situation in Darjeeling.
As many as six parties including the GJM and the BJP have adopted a resolution for a separate Gorkhaland state.
West Bengal Chief Minister Mamata Banerjee has branded the GJM protest as 'abhorrent' and appealed to the people of the region to maintain peace.
