Power under Section 21 of General Clauses Act not available for varying quasi judicial orders

(2018) 4 SCC 494

  The general power, under Section 21 of the General Clauses Act, to rescind a notification or order has to be understood in the light of the subject matter, context and the effect of the relevant provisions of the statute under which the notification or order is issued and the power is not available after an enforceable right has accrued under the notification or order. Moreover, Section 21 has no application to vary or amend or review a quasi judicial order. A quasi judicial order can be generally varied or reviewed when obtained by fraud or when such power is conferred by the Act or Rules under which it is made.
