거주자와 과세관청 쌍방이 준수해야 할 신의칙

Abstract

The Principle of Good Faith and Fair dealing is applicable to the case of public law as well as civil law. Also it is applicable to the tax payer as well as tax authorities. This principle has been adopted in the National Tax Law. If this principle is applicable to the tax payer, court should proclaim to maintain the administrative measure although it is illegality. Korean Supreme court required three necessary conditions, when the principle is applied. Tax payer’s self-contradictory behavior, severe betrayal and worth of tax authorities’s trust. But actually we can hardly find the case which maintain the illegal administrative measure in the name of that principle. The case would studied in this paper was about the principle. Supreme court was applicable the principle, so maintained the illegal administrative measure. It is so the extaordinary case. But it is more or less questionable that tax payer did the severe betrayal and whether protect the tax authority’s trust.
