49. Now in this backdrop, it becomes necessary to emphasise that before the Commissioner can levy a provisional attachment, there must be a formation of “the opinion” and that it is necessary “so to do” for the purpose of protecting the interest of the government revenue. The power to levy a provisional attachment is draconian in nature. By the exercise of the power, a property belonging to the taxable person may be attached, including a bank account.

An attachment which is contemplated in Section 83 is, in other words, at a stage which is anterior to the finalisation of an assessment or the raising of a demand. Conscious as the legislature was of the draconian nature of the power and the serious consequences which emanate from the attachment of any property including a bank account of the taxable person, it conditioned the exercise of the power by employing specific statutory language which conditions the exercise of the power. The language of the statute indicates first, the necessity of the formation of opinion by the Commissioner; second, the formation of opinion before ordering a provisional attachment; third the existence of opinion that it is necessary so to do for the purpose of protecting the interest of the government revenue; fourth, the issuance of an order in writing for the attachment of any property of the taxable person; and fifth, the observance by the Commissioner of the provisions contained in the rules in regard to the manner of attachment. Each of these components of the statute are integral to a valid exercise of power.

While conditioning the exercise of the power on the formation of an opinion by the Commissioner that “for the purpose of protecting the interest of the government revenue, it is necessary so to do”, it is evident that the statute has not left the formation of
