The hearing listed for Thursday has been put off to August 17. Tamil Nadu has meanwhile filed an additional plea seeking its full monthly allocation, putting the shortfall at Biligundlu at 26.954 TMC.
The Supreme Court has deferred its hearing of Tamil Nadu's Cauvery petition to August 17. The matter had been listed for Thursday after an urgent mentioning earlier in the week, but the bench headed by Chief Justice Surya Kant indicated the case would be taken up when the bench is next available. The petitions filed by the Tamil Nadu government and by the DMK are both expected to be heard together on that date.
The state has not waited idle for the new date. Having filed its first response in the matter on August 12, the Tamil Nadu government has now submitted an additional petition seeking a direction to Karnataka to release more water. Its argument is that under the monthly water-sharing schedule laid down by the Supreme Court, Tamil Nadu must receive its allocation in full, and that partial releases are not acceptable.
The state is represented by senior advocates C. S. Vaidyanathan and G. Umapathy, along with advocate P. Karunakaran. Their petition asks the court to direct implementation of the Cauvery Water Management Authority's order of July 30 — requiring releases from the Kabini and Krishna Raja Sagara reservoirs at 3,500 cusecs per day for 15 days, amounting to 4.536 TMC reaching Biligundlu.
| Date | Development |
|---|---|
| July 28 | CWRC orders 3,500 cusecs at Biligundlu for 15 days |
| July 30 | CWMA upholds the order, rejects Karnataka's appeal |
| August 3 | Tamil Nadu moves the Supreme Court |
| August 10 | Court lists the matter for August 13 |
| August 11 | CWRC raises its direction to 12,000 cusecs per day |
| August 12 | Tamil Nadu files first response; additional plea follows |
| August 17 | Hearing now listed — TN and DMK petitions together |
The deferral means the legal question remains open while the irrigation calendar moves on. The CWRC's direction of August 11, raising the required release to 12,000 cusecs per day for 15 days from August 12, runs in parallel with the court proceedings — and whether Karnataka complies with it will likely shape what the court is told next week.
Tamil Nadu's underlying position, set out when it first approached the court on August 3, is that both the quantum allocated by the regulatory bodies and the volume Karnataka has actually released fall short of what the state is owed in a rain-deficient year. CM Vijay defended his government's approach in the Assembly on August 7, saying he was prepared to face humiliation for Tamil Nadu's rights and would pursue every legal avenue available.
