Supreme Court en banc Decision ‘2016Da264556’ decided January 24, 2019.(hearafter ‘THE JUDGEMENT’) can be estimated to be the Supreme Court's final official and judicial opinion on the legitimacy regarding the Doctrine of the “landowner's relinquishment of exclusive use and beneficiary rights” that has been formed by the Supreme Court rulings for a long time. In addition to the standard set forth in the previous Supreme Court ruling, THE JUDGEMENT reqires an additional standard for 'limitation landowner's exclusive use and beneficiary rights', which is to review balancing the interest between the guarantee of ownership of the landowner and the public interest. and THE JUDGEMENT also provides that Specific successor can be permitted to have exclusive use and beneficiary rights in some cases. Most of all, THE JUDGEMENT is made clear by the supplementary opinions of the majority opinion that the Doctrine is “based on the intention of the landowner on the premise of the principle of private autonomy”. In other words (I think) the Doctrine is not an ‘Entscheidung Norm(legal norm)’ created by the court to cope with the social phenomenon that occurred in the background of Korea's unique reality but a ‘Reasonable standard’ for determining whether a claim held by a landowner meets the requirements, as the standard for interpretation of intention or legal act. I think this is the most special meaning of THE JUDGEMENT.
