In a letter to Singh, Chief Minister Oommen Chandy urged the Centre not to accept the recommendations of the panel holding that the "new method would be totally against the provisions of the constitution and the concept of fiscal federalism".
The panel had made a case for ending 'special category' criteria to provide additional assistance to poorer states, as it ranked Goa and Kerala as the most advanced states and Odisha and Bihar the least.
Chandy said "It would be totally against the provisions of the constitution the concept of fiscal federalism and the existing scheme of devolution of development funds by the Planning Commission to even consider any of the recommendations of the committee.
Stating that the methodology adopted by the committee was "seriously flawed" as it does not include major economic factors, Chandy said the Panel also had not held consultation with states and other stakeholders.
Distribution of resources as recommended by the panel would only help to aggravate existing imbalances, Chandy said.
