The apex court had permitted Maharashtra government to proceed with the dam project in Apr 2007.
But Andhra Pradesh had claimed that the Babli Barrage was being constructed within the backwaters of the Pochampad Dam in the Telangana region.
Andhra Pradesh also claimed that Maharashtra is violating the GWDT agreement of Oct 1975, and challenged the matter in the Supreme Court.
TDP chief N Chandrababu Naidu with his other associates were arrested when they were trying to enter into the project site to verify the situation on Jul 16.
But Maharashtra government finally had withdrawn its charges against TDP leader and send him to Hyderabad.
