  • The Centre had in 1980 accepted the verdict of Godavari Water Disputes Tribunal and made it binding on the concerned river basin states.
  • According to the tribunal’s verdict, the agreements arrived between the riparian states at the sub-basin level were vetted by the states of the entire Godavari basin and no state could back out of the total tribunal award.
  • Recently, a petition was filed by an NGO, RELA which submitted that the dam design had been changed and new components added, thus requiring a new environmental clearance
  • Primary among the questions being considered by the Bench is whether the dam project and its design, as approved by the Central Water Commission, is in consonance with the Godavari Water Disputes Tribunal (GWDT) award of 1980.
  • Crucially, the court has to examine whether the change in the design, especially in so far as it raises the spill-way discharge capacity from 36 lakh cusecs to 50 lakh cusecs, is so fundamental that it amounts to violation of the GWDT Award, and, therefore, requires fresh statutory clearances to be obtained.
  • Also, a series of 13 questions were framed by the Bench in a suit filed by Odisha against Andhra Pradesh in 2007. Among them, the court had also decided to look into the back water effect of the project.
  • Also, the court has directed the Centre to file an affidavit detailing the conduct of the public hearing, including which government agency would hold it. The court said it would pass orders on 3 December 2018.
