The police on Thursday decided not to allow hardline Hurriyat seminar on West Pakistan (WP) refugees in Srinagar.
The authorities placed a number of separatists of several factions of the Hurriyat under house arrest to prevent them from attending the seminar.
The Syed Ali Geelani's faction of the Hurriyat was planning to organise a day-long seminar in Srinagar to discuss the Union home ministry and Joint Parliamentary Committee's fresh recommendation in favour of granting more rights to the WP refugees living in the state.
Top separatist leaders placed under house arrest, included Mohammad Ashraf Sehrai, Ayaz Akbar, Peer Saifullah, Mairaj Din Kalwal and Shabir Ahmad Shah.
Most of these leaders were disallowed to move out of their houses since Wednesday evening.
"Such restrictions reflect frustration of the authorities. On one hand, they are making tall claims of democracy and on the other bans political activities," said Democratic Freedom Party (DFP) secretary general Moulana Muhammad Abdullah Taari.
Geelani is himself in New Delhi, where he is undergoing medical treatment for his kidney ailment.
