This discussion clarifies who is the competent authority to cancel a legal heir certificate obtained fraudulently in Tamil Nadu. While some believe only a court can cancel it, others suggest a higher official in the Revenue Department holds this power. The consensus leans towards the Revenue Divisional Officer (RDO) or Sub-Collector having jurisdiction, with possibilities of administrative appeals and even criminal action for fraudulent issuance. A news report highlights a High Court directing a Tahsildar to cancel and re-issue a certificate.
