(2)If any building, place, vessel, vehicle or aircraft referred to in sub-section (1)(i) is within the area of jurisdiction of any Principal Chief Commissioner or Chief Commissioner or Principal Commissioner or Commissioner, but such income-tax authority has no jurisdiction over the person referred to in sub-section (1)(a) or (b), then, irrespective of the fact that he has no jurisdiction, it shall be competent for such income-tax authority to exercise the powers under sub-section (1), where he has reason to believe that any delay in getting the authorisation from the Principal Chief Commissioner or Chief Commissioner or Principal Commissioner or Commissioner having jurisdiction over such person may be prejudicial to the interests of the revenue.
