A letter from Bengaluru to New Delhi is now carrying the weight of millions of aspirations. Karnataka Chief Minister D.K. Shivakumar has formally written to Prime Minister Narendra Modi, urging his personal intervention to shield the state's enhanced SC/ST reservation law from judicial invalidation — by placing it in the Ninth Schedule of the Constitution.

The Law at the Centre of the Fight

The legislation in question — Karnataka Act No. 1 of 2023, formally titled the Karnataka Scheduled Castes and Scheduled Tribes (Reservation of Seats in Educational Institutions and of Appointments or Posts in the Services under the State) Act, 2022 — raises reservation for Scheduled Castes from 15% to 17% and for Scheduled Tribes from 3% to 7% in education and public employment. The Act received the Governor's assent on 11 January 2023 and was deemed to have come into effect from 1 November 2022.

The enhanced quotas were not arbitrary. They followed the recommendations of a commission headed by retired Karnataka High Court judge Justice H.N. Nagamohan Das, whose panel examined the social and educational disadvantages faced by these communities alongside their actual share in Karnataka's population — and concluded that 17% for SCs and 7% for STs was both justified and necessary.

How the Karnataka High Court Struck It Down

The legislation's journey hit a constitutional wall on 12 October 2026, when the Karnataka High Court invalidated the enhanced reservation provisions on two grounds: the enhanced quotas breach the 50% ceiling on reservations established by the Supreme Court in the landmark Indra Sawhney v Union of India (1992) judgment, and the state failed to undertake mandatory consultations with the National Commissions for SCs and STs under Articles 338(9) and 338A(9) of the Constitution. The state government is now pursuing an appeal before the Supreme Court.

But litigation alone is not the end-game here. Shivakumar's letter signals that Karnataka is simultaneously pursuing a legislative route — one that bypasses the 50% ceiling entirely by seeking Ninth Schedule protection, the same constitutional armour that Tamil Nadu used in 1994 when Parliament inserted its 69% reservation law into the Ninth Schedule through the 76th Constitutional Amendment.

A Trail of Proposals Before This Letter

This is not Karnataka's first attempt to move the Centre. Shivakumar's letter catalogues a sustained, multi-year campaign: the state submitted a formal proposal to the Union Government on 23 March 2023; the Karnataka Legislative Assembly passed a resolution on 18 December 2025; and former Chief Minister Siddaramaiah wrote to the Prime Minister on 16 April 2026. The Union Government acknowledged receipt of the proposal in the Lok Sabha on 25 July 2026 — but acknowledgment is not action.

Shivakumar is now asking for something concrete: that the Prime Minister initiate the process for an appropriate Constitutional Amendment Bill to include the Act in the Ninth Schedule, facilitate consultations with the National Commissions for SCs and STs, and direct the Ministries of Law and Justice, Social Justice and Empowerment, Tribal Affairs, and Home Affairs to undertake a coordinated, time-bound examination. The state has offered full cooperation in supplying empirical material to support the constitutional case.

Why the Ninth Schedule Is the Only Durable Shield

The Ninth Schedule, introduced by the First Constitutional Amendment in 1951, was designed to protect land reform laws from property-rights challenges. Over decades, it has grown into a refuge for politically sensitive legislation that courts might otherwise strike down. Laws placed in it are shielded from fundamental-rights challenges — though the Supreme Court ruled in I.R. Coelho v State of Tamil Nadu (2007) that this protection is not absolute if a law damages the Constitution's basic structure.

For Karnataka, Ninth Schedule inclusion would neutralise the 50% ceiling argument and render the High Court's judgment moot — provided Parliament agrees to amend the Constitution. That is a significant 'if', requiring a two-thirds majority in both Houses and ratification by at least half the state legislatures. Karnataka's political calculus is that a public, on-record request to the Prime Minister makes the Centre's response — or silence — equally consequential.

With the Supreme Court appeal pending and Parliament's winter session on the horizon, the next move belongs to New Delhi — and Karnataka has made sure the whole country is watching.
