By providing such a reservation, the school created an "arbitrary separation" between the children of Group-A officers and all other students, a bench of justices Pradeep Nandrajog and Mukta Gupta said.
It also said that "the State cannot provide funds to any private individual to establish a school for an elite segment of the society" and directed the government to "remediate this violation, and ensure that the school in question open its doors equally to all students".
"The school possesses no justifiable basis upon which to label group-A Union Government officers as a suspect class. No logical rationale distinguishes this class of persons from other individuals engaged in other branches of the Indian Services," it said.
It said if the reservation in place to provide stable schooling environment for children of officers whose assignments "fluctuate" between different geographic locations in India, "the justification is moot", as this predicament was being faced by all persons engaged in other branches of the Indian services.
"Thus, a classification that includes merely the children of group-A Union Government officers bears no merit. In sum, the respondents' separate treatment of aforesaid classification of children violates both the spirit of equal protection under Article 14 of India's Constitution and the spirit of equality of education under Article 21A," the bench said.
