This document contains the original judgement from the High Court of Judicature at Madras concerning the case of G. Sakthi Rao versus the Government of Tamil Nadu and others. The judgement addresses the interpretation and application of the Tamil Nadu Appointment on Preferential Basis in the Services under the State of Persons Studied in Tamil Medium (PSTM) Act, 2010. It clarifies eligibility criteria for the PSTM quota in public service recruitment, particularly regarding whether candidates must have completed their entire education in Tamil medium or just the prescribed qualification for the post. This judgement is crucial for understanding the nuances of language-based reservation policies in Tamil Nadu.
