Represented the Ministry of Land, Infrastructure and Transport and achieved a victory in a lawsuit filed by plaintiffs, consisting of members of the National Assembly and citizens, seeking the cancellation of real estate measures (Seoul Administrative Court, Judgment pronounced on January 29, 2026, Case No. 2025GuHap56119).

This case originated from the government's announcement on October 15, 2025, of real estate measures expanding the scope of designated regulation zones to all of Seoul and 12 regions in Gyeonggi Province. Designation as a regulation zone triggers strict regulations, including strengthened actual residence requirements and lowered Loan-to-Value (LTV) ratios for housing mortgages. The plaintiffs argued that these real estate measures severely infringed upon their property rights and, in particular, that the Ministry of Land, Infrastructure and Transport intentionally misused housing price statistics serving as the basis for designating regulation zones.

In response, Lee & Ko's Administrative Litigation (Appeal) team argued that the government possesses broad discretion in formulating real estate policies. Furthermore, the team contended that since housing price statistics for September were not available at the time of designating the regulation zones, the government had no choice but to utilize existing data, and the fact that September housing price statistics were announced just before the additional designation of regulation zones did not affect the legality of the measures.

Considering the importance and urgency of the matter, the court proceeded with the trial swiftly. As a result, only two months after the lawsuit was filed, in January 2026, the court accepted all of Lee & Ko's arguments and dismissed the plaintiffs' claims. This case is evaluated as one where Lee & Ko's Administrative Litigation (Appeal) team demonstrated its ability to respond swiftly and accurately to government regulatory policies.
