Summary

Story summary

India rejected the Permanent Court of Arbitration’s ruling that it must uphold the 1960 Indus Waters Treaty.
The court ordered India to limit construction on the Ratle hydroelectric project and barred concrete above specified levels.
The restriction remains until 90 days after a Bank-appointed neutral expert decides, expected by July 2027.
Pakistan’s ministers Attaullah Tarar and Ishaq Dar said the award vindicates Pakistan and obliges India to comply.

History

In 1993 the International Court of Justice began hearing the Gabcíkovo-Nagymaros dispute between Hungary and Czechoslovakia, a landmark trans-boundary water case. That precedent, echoed in the 1974 Fisheries Jurisdiction case (Germany v. Iceland), underpins today’s arbitration forcing India to stop work on the Ratle dam, a move praised by Pakistan’s Attaullah Tarar and Ishaq Dar.
