New Delhi: Expressing concern over the failure of state governments to comply with its directions to enhance stray dog sterilisation capacity, the Supreme Court on Wednesday remarked that states were “building castles in the air”. Senior advocate Gaurav Agarwal, the amicus curiae in the matter, outlined steps taken by various states while highlighting serious deficiencies. The amicus said states must significantly expand animal birth control (ABC) facilities, scale up sterilisation of stray dogs, establish dog pounds or shelters, fence institutional areas, and remove stray animals from roads and highways. The Bench observed that most states had failed to provide data on stray dog bites. The Supreme Court is hearing a suo motu case initiated on July 28 last year following media reports on stray dog attacks and rabies cases, particularly affecting children in the national capital.
