IBRAHIMPATNAM TALUK VYAVASAYA COOLIE vs SURESH REDDY .

The Supreme Court addressed the interpretation of sub-section (4) of Section 50-B of the Andhra Pradesh (Telangana Area) Tenancy and Agricultural Land Act, 1950, determining that the Collector's suo-motu power to cancel validation certificates must be exercised within a reasonable time, despite the statute's wording allowing for action 'at any time'. The Court upheld the High Court's decision that the Joint Collector acted beyond the reasonable time frame in cancelling the certificates, thus affirming the validity of the earlier validation certificates issued by the Tahsildar. The appeals were dismissed, reinforcing the principle of timely exercise of administrative powers.
