As per case facts, appellant Zubair P was appointed as HSST (Economics) but his appointment was rejected for lacking subject-specific SET qualification, holding SET only in Malayalam. Respondent No. 4, ... with SET in Economics, challenged this appointment. The High Court upheld the rejection. The appellant appealed, contending that Rule 6.2(24)(iii) of the Rules does not mandate a subject-specific SET. The question arose whether the SET qualification for HSST must be in the concerned subject or if any SET qualification suffices. Finally, the Supreme Court ruled that a contextual reading of Rule 6 and the SET exam prospectus implies that the SET qualification must be in the concerned subject, despite the textual omission in the Rule. The intent to ensure subject competence at the Higher Secondary level requires subject-specific SET, and an unrelated SET is insufficient. The High Court's judgment was affirmed.
