Section 269UA(2)(iii)(f) of the Act clearly says that any lease for a term of not less than twelve years and includes holding possession of such property thereby taken, has to be construed as transfer. Of course, this is in the context of purchase of property by Central Government in the case of transfer. In other words, Section 269UA(2)(iii)(f) also defines transfer which includes lease for a term not less than twelve years. In this case, admittedly, the lease was not for less than twelve years. Hence, for all practical purposes, the acquisition of property by perpetual lease exceeding the period of twelve years, has to be construed as purchase within the meaning of Section 54F of the Act. In view of the scheme under the provisions of the Income-tax Act, as enunciated under Section 2(47)(vi) and Section 269UA(2)(iii)(f), this Tribunal is of the considered opinion that when the assessee acquired the residential house by means of perpetual lease exceeding twelve years, it has to be construed as acquisition of property / purchase of property within the meaning of Section 54F of the Act. Therefore, the assessee is entitled for exemption under Section 54F of the Act. Hence, this Tribunal is unable to uphold the order of the Principal Commissioner passed under Section 263 of the Act. Accordingly, the impugned order of the Principal Commissioner is quashed.
