STATE OF TAMIL NADU vs A. GURUSAMY

The Supreme Court held that the civil suit filed by the respondent for declaring himself as 'Kattunaicken', a Scheduled Tribe, is not maintainable as per Section 9 of the CPC. The Court emphasized that the declaration made by the President under Articles 341 and 342 of the Constitution regarding Scheduled Castes and Scheduled Tribes is conclusive and cannot be challenged in civil courts. The Court upheld the cancellation of the respondent's community certificate, affirming that he was given a fair opportunity to present his case before the authorities, and the findings of the District Collector were justified.
