ROOP CHAND ADLAKHA AND ORS. vs DELHI DEVELOPMENT AUTHORITY AND ORS.

The Supreme Court upheld the validity of the rules prescribed by the Delhi Development Authority (DDA) regarding the promotion of Junior Engineers to Assistant Engineers and Executive Engineers, which differentiated between Graduates and Diploma-Holders based on service experience. The Court found that such differentiation does not violate Articles 14 and 16 of the Constitution, as it is justified by the need for higher technical qualifications for advanced posts. The appeal against the High Court's decision, which had declared the rules unconstitutional, was allowed, affirming the DDA's promotion criteria.
