Principle of Estoppel by Conduct and Representation against the State

The rule of estoppel operates forcefully against a litigant, including the State and its authorities, when its deliberate conduct and express written representations have led the executing court and the decree-holder to proceed on the basis that the execution was properly and accurately executed. When official revenue personnel and office amins participate in the demarcation exercise, append their signatures to the delivery notice and report, and the State officially confirms that no anomaly has been reported and registers no objection, the State is legally estopped from disputing the correctness of the possession delivered. The principles of fair play and administrative accountability prevent government authorities from casually repudiating their own official verifications and memos. Once the executing court acts upon the State's clear no-objection and enters full satisfaction of the decree, the State cannot be heard to allege mistake or misdirection, as its prior conduct creates an insurmountable legal estoppel.
