1. Article 78(5) of the Act on Acquisition of and Compensation for Land, etc. for Public Works Projects (hereinafter “Public Works Projects Act”) provides that “the residents of a residential building shall be compensated by calculating the cost necessary for relocation of the residential building and the cost necessary for the transportation of movable property, such as household facilities,” and Article 78(9) of the same Act provides that “The compensation under paragraphs (5) and (6) shall be governed by the standards prescribed by Ordinance of the Ministry of Land, Transport and Maritime Affairs.” Under such delegation, Article 54(2) of the former Enforcement Rule of the Act on Acquisition of and Compensation for Land, etc. for Public Works Projects (amended by Ordinance No. 556 of the Ministry of Construction and Transportation, Apr. 12, 2007; hereinafter “former Enforcement Rule”) provides that the tenants of a residential building who resided in the residential area due to the implementation of public work projects shall also be entitled to compensation for the relocation of the residential building within three months or more according to the amended Enforcement Rule of the Public Works Projects Act, including the relocation of the residential building within five months or more.”

Meanwhile, Article 40(1) of the former Act on the Maintenance and Improvement of Urban Areas and Dwelling Conditions for Residents (amended by Act No. 9444, Feb. 6, 2009; hereinafter “former Act”) provides that “Except as otherwise provided for in this Act, the Act on the Acquisition of Land, etc. for Public Works and the Compensation Therefor shall apply mutatis mutandis to the expropriation or use of the ownership of or other rights to the land or buildings for the implementation of a rearrangement project within a rearrangement zone.” The main sentence of Article 31(1) provides that “where the head of a Si/Gun intends to implement a project implementation plan or to prepare a project implementation plan, he/she shall make the relevant documents available for public perusal for at least 30 days in accordance with the methods and procedures prescribed by Presidential Decree.” Article 42 of the former Enforcement Decree of the Act on the Maintenance and Improvement of Urban Areas and Dwelling Conditions for Residents (amended by Presidential Decree No. 21679, Aug. 11, 2009; hereinafter “former Enforcement Decree”), the head of a Si/Gun shall make public announcement or public announcement of the relevant project implementation plan.

With the contents, form, system, legislative intent, etc. of the above relevant Acts and subordinate statutes, housing relocation expenses are the nature of social security for tenants who will suffer special difficulties due to their relocation of residence by encouraging early relocation of tenants residing in the relevant project implementation zone (see Supreme Court Decisions 2006Du2435, Apr. 27, 2006; 2009Du16824, Sept. 9, 2010, etc.). In addition, in order to implement housing redevelopment project, it is not clear whether the project implementer requested the payment of housing relocation expenses has not been determined at the time of the public inspection and announcement of the improvement plan, and it is sufficient that the project implementer can expropriate land, things, and other rights if necessary for the improvement project after the approval and announcement of the project implementation plan, it shall be deemed that the implementation plan is subject to the public inspection and announcement of the improvement plan under the former Act, and if it is necessary to implement the housing redevelopment project, it shall be deemed that the method and announcement of the compensation plan under the former Act is within the scope of the project implementation plan.

In so doing, the court below did not err by misapprehending the legal principles as to the application of the new Enforcement Rule, as
