State of Kerala v N.M. Thomas
Article 16(4) is not an exception to but an emphatic illustration of the equality of opportunity guaranteed by Article 16(1), so preferential treatment of backward classes flows from equality itself.
Facts
Kerala granted SC/ST government employees a temporary exemption from passing a departmental qualifying test required for promotion, allowing them additional time. A general-category employee challenged the concession as a violation of the equality of opportunity guaranteed in public employment under Article 16(1).
Issues
- Whether preferential treatment of SC/ST employees in promotion outside Article 16(4) violated Article 16(1)
- Whether Article 16(4) is an exception to, or an illustration of, the equality clause in Article 16(1)
- Whether caste could be used as the criterion to identify a backward class
Arguments
The challenger argued the concession was discriminatory and breached formal equality of opportunity in public employment. The State contended that classification favouring backward groups was permissible under Articles 16(1) and 14 read with the directive to promote weaker sections, independent of Article 16(4).
Held
The majority upheld the concession, holding that equality under Articles 14 and 16(1) is substantive, not merely formal, so that unequals need not be treated equally. Ray CJ reasoned that the question of unequal treatment does not arise between persons governed by different conditions and circumstances. Article 16(4) was characterised as an emphatic illustration of, rather than an exception to, the equality guaranteed by Article 16(1). The judgment also accepted that caste could be used as the criterion to identify a backward class.
Ratio decidendi
The equality guarantee of Article 16(1) embodies substantive equality and itself permits favourable treatment of backward classes; Article 16(4) merely illustrates this principle rather than carving out an exception to it.
Significance
Landmark that shifted Indian equality jurisprudence from formal to substantive equality and seeded the 'creamy layer' concept; its 16(4)-as-illustration reasoning was adopted by the majority in Indra Sawhney and underpins the constitutional logic of reservations.
