(viii) Insofar as the contention advanced by the respondents – State that Section 21 of the General Clauses Act enables them to withdraw the circular dated 02.07.2020 and order dated 05.05.2021, having regard to the peculiar and special facts and circumstances of the instant case including the aims and objects of the ICDS scheme, directions issued by the Apex Court and other proceedings, orders etc., prior to issuance of the same, respondents were not entitled to unilaterally and unconditionally issue the impugned orders under Section 21, which does not confer unfettered or unbridled powers on the State Government to withdraw its earlier order dated 05.05.2021, that too within a period of fifteen days and as such, even this contention of the respondents is liable to be rejected. It is well settled that exercise of power under Section 21 of the General Clauses Act is circumscribed, limited and restricted by the attending and surrounding facts and circumstances including the instant circular / order sought to be withdrawn and in the facts of the case on hand, particularly having regard to the ICDS scheme which is beneficial in nature, effective and speedy implementation of the scheme was absolutely essential and consequently, the impugned orders are vitiated on this ground also.
