Section 293c of Income Tax Act "Power to withdraw approval"
293C. Where the Central Government or the Board or an
income-tax authority, who has been conferred upon the power
under any provision of this Act to grant any approval to any
assessee, the Central Government or the Board or such
authority may, notwithstanding that a provision to withdraw
such approval has not been specifically provided for in such
provision, withdraw such approval at any time :
Provided that the Central Government or Board or income-tax
authority shall, after giving a reasonable opportunity of
showing cause against the proposed withdrawal to the
assessee concerned, at any time, withdraw the approval after
recording the reasons for doing so.
294. If on the 1st day of April in any assessment year provision has not yet been made by a Central Act for the charging of income-tax for that assessment year, this Act shall nevertheless have effect until such provision is so made as if the provision in force in the preceding assessment year or the provision proposed in the Bill then before Parliament, whichever is more favourable to the assessee, were actually in force.
