Karnataka signals reopening of the Cauvery allocation question
Quick dive
- Karnataka told the Supreme Court that inter-State water allocations may be revisited in changed circumstances, invoking the principle rebus sic stantibus.
- The 2018 Supreme Court allocation, based on a tribunal award, apportioned 740 TMC ft at 50% dependability: Karnataka 284.75, Tamil Nadu 404.25, Kerala 30 and Puducherry 7 TMC ft.
- Karnataka cited a second-lowest southwest monsoon in 70 years, with 551 mm against a normal 852 mm, and disputed a fixed pro-rata distress-sharing formula.
- The State’s reply also referred to environmental flows and inevitable wastage into the sea, while Tamil Nadu’s complaint concerns backlog in water release.
- exam_relevance: asks the precise 740-TMC-ft allocation, State-wise shares, 50% dependability and rebus sic stantibus claim, building on UPSC’s repeated questions on river-water tribunals, federalism and inter-State disputes; the altered-monsoon argument makes this more than a routine release controversy.
