Current status

Tamil Nadu is the custodian of the dam and its surrounding areas. In 2006, the Supreme Court of India by its decision by a single bench, allowed for the storage level to be raised to 142 feet (43 m). However, the Kerala Government promulgated a new "Dam Safety Act" against increasing the storage level of the dam, which has not been objected by the Supreme Court. Tamil Nadu challenged it on various grounds. The Supreme Court issued notice to Kerala to respond; however, did not stay the operation of the Act even as an interim measure. The Court then advised the States to settle the matter amicably, and adjourned hearing in order to enable them to do so. The Supreme Court of India termed it as not unconstitutional. Meanwhile, the Supreme Court constituted a Constitution bench to hear the case considering its wide ramifications. The case involves pre-constitutional agreement between two entities which does not exist now.
Kerala's Stance: Kerala did not object giving water to Tamil Nadu. Their main cause of objection is the dams safety as it is as old as 110 years. Increasing the level would add more pressure to be handled by already leaking dam.
Tamil Nadu's Stance: The State wants that the 2006 order of Supreme court be implemented so as to increase the water level to 142 feet (43 m).
