Soon after the RTE Act was enacted, several private schools challenged its constitutional validity in the Supreme Court. The main challenge was against its provision that mandated private schools to fill 25% of the seats in Class I with children from weaker and disadvantaged groups. Petitioners argued that this imposition was an unreasonable restriction on their right to carry on a trade or business under Article 19(1)(g). In these petitions, CLPR represented the Azim Premji Foundation as an intervenor to not only support the RTE Act but seek for a broader interpretation to include children between 0-6 years.
