A notification issued by the government on June 5 said the matter was reviewed and after consideration of the overall law and order situation of the state, the areas were reduced.
The act was first put into effect in 40 of the total 70 police station areas in the state in February 1997, when the conflict between the insurgents and security forces were at its peak. Now it would be effective fully in 25 police station areas, and partly in seven.
The two banned outfits - National Liberation Front of Tripura (NLFT) and the All Tripura Tiger Force (ATTF) are still operating from their base in neighbouring Bangladesh.
