If the submission of the appellant is accepted and the concerned expression as stated hereinabove in Section 246(1)(a) or in Section 246A(1)(a) is to be considered as relatable to the liability of an assessee to be assessed under Section 143(3) as contended, there would be no appellate remedy in case of any determination under Section 115QA. The issues may arise not just confined to the question whether the company is liable at all but may also relate to other facets including the extent of liability and also with regard to computation. If the submission is accepted, every time the dispute will be required to be taken up in proceedings such as a petition under Article 226 of the Constitution, which normally would not be entertained in case of any disputed questions of fact or concerning factual aspects of the matter. The assessee may thus, not only lose a remedy of having the matter considered on factual facets of the matter but would also stand deprived of regular channels of challenges available to it under the hierarchy of fora available under the Act
