regulations abrogating the provisions therein conforming to the provisions of Section 29-A(5) or intimating the Commission that it has ceased to have faith and allegiance to the Constitution of India or to the principles of socialism, secularism and democracy, or it would not uphold the sovereignty, unity and integrity of India so as to comply with the provisions of Section 29-A(5). In such cases, the very substratum on which the party obtained registration is knocked off and the Commission in its ancillary power can undo the registration of a political party. Similar case is in respect of any like ground where no enquiry is called for on the part of the Commission. In this category of cases, the case would be where a registered political party is declared unlawful by the Central Government under the provisions of the Unlawful Activities (Prevention) Act, 1967 or any other similar law. In such cases, power of the Commission to cancel the registration of a political party is sustainable on the settled legal principle that when a statutory authority is conferred with a power, all incidental and ancillary powers to effectuate such power are within the conferment of the power, although not expressly conferred. But such an ancillary and incidental power of the Commission is not an implied power of revocation. The ancillary and incidental power of the Commission cannot be extended to a case where a registered political party admits that it has faith in the Constitution and principles of socialism, secularism and democracy, but some people repudiate such admission and call for an enquiry by the Election Commission, reason being, an incidental and ancillary power of a statutory authority is not the substitute of an express power of review.
