If after any scheme has come into force, the State Government, on an application made to it or suo motu, is satisfied that the scheme is defective on account of any error, irregularity or informality or on account of any other reason it is necessary to vary the scheme, then,-
(a) where, in the opinion of the State Government, the proposed variation does not vary the scheme in any material particulars, the State Government may, by order, published in the prescribed manner in the village, and at the headquarters of the taluka, in which in the lands included in the scheme are situated, sanction the variation;
(b) where, in the opinion of the State Government, the proposed variation would vary the scheme in any material particulars, the State Government may cause such variation to be published for inviting objections as if it were a draft scheme to be published under sub-section (1) of section 7, and the provisions of sections 7, 8 and 9 shall apply for sanctioning, coming into force and execution of such variation, as if such variation was itself a scheme.
