2. We examine the grounds of appeal 2.

According to the reasoning of the judgment below, the court below acknowledged the fact that the plaintiff sold five new houses during the period from February 26, 1986 to March 18, 198 by the evidence of the judgment, and revoked the disposition of imposition of value-added tax or global income tax on the five five transactions, on the ground that the general rule of the Income Tax Act (amended by February 1, 1988) is illegal, since it is difficult to see that there is business income tax or business feasibility under Article 20 (1) 8 of the Income Tax Act in light of the fact that the general rule of the Income Tax Act (amended by Presidential Decree No. 1988, Feb. 1, 1988) is deemed to be a construction business in the case where one or more houses are

However, whether the new construction transfer of real estate constitutes a requirement for taxation of business income tax and value-added tax shall be determined according to social norms by considering whether the new construction transfer is for profit and whether it has continuity and repetition of business to the extent that it can be seen as business activity in light of its size, frequency and attitude.

3. We examine the grounds of appeal No. 3.

The court below recognized the fact that the defendant's account books and documentary evidence are incomplete and led to the decision of estimated assessment of global income tax, etc. of this case. The court below determined that the decision of estimated assessment of global income tax of this case was unlawful on the ground that the defendant did not prove the rationality and validity of the decision of estimated assessment, and that the account books and other documentary evidence were submitted during the lawsuit of this case.
