STATE OF PUNJAB vs STATE OF HARYANA & ORS.

The Supreme Court addressed the interlocutory application filed by the State of Punjab seeking to restrain the State of Haryana from constructing a concrete toe wall on the Hansi Branch – Bhutana Branch Multipurpose Link Channel. The Court emphasized the principle of cooperative federalism and territorial integrity, holding that the construction could lead to increased backwater flow and potential damage to Punjab's territory. The Court granted the interim injunction, thereby preventing Haryana from proceeding with the construction until further orders.
