2025 (Gyo-Ko) No. 24 Appeal Case Seeking Revocation of Public Assistance Benefit Reduction Based on Lowered Livelihood Protection Standards

In 2025, the Supreme Court of Japan delivered its final judgment in the appeal case concerning the reduction of public assistance benefits. Starting in 2013, the Japanese government decided to lower the national livelihood protection standards in phases, resulting in decreased monthly payments for recipients. Multiple recipients, including Tetsuo Kokubo and Yoshio Nakanishi, filed lawsuits arguing that the reduction violated their constitutionally guaranteed right to a minimum standard of living. The lower courts had ruled the government's decision illegal, stating that the administrative discretion was abused because the reduction lacked a reasonable basis and failed to adequately consider the actual living conditions of impoverished households. The government appealed, and the case reached the Supreme Court in 2025. The court examined whether the welfare ministry's method for setting and lowering the standards deviated from the legislated purpose of guaranteeing a healthy and cultural minimum life.

The Supreme Court dismissed the government's final appeal, affirming the high court's ruling that the reduction of benefits was illegal. The benefit reduction orders were revoked, and the state was held liable for damages in related cases, establishing that the criteria used to lower the standards were unreasonable and procedurally flawed.

Whether the government's phased reduction of livelihood protection standards constituted an illegal abuse of administrative discretion exceeding the boundaries of delegated authority, and whether such reductions violated Article 25 of the Constitution by failing to ensure the minimum standard of living necessary for health and culture.

The ruling had a profound impact on Japan's social security policy. It reaffirmed the judiciary's role in reviewing the substantive content of administrative decisions on minimum subsistence levels. It halted further arbitrary benefit cuts and forced the government to adopt more transparent, evidence-based methods for calculating welfare standards. The decision strengthened the legal protection of vulnerable populations and sparked renewed public debate on poverty, inflation, and the adequacy of the social safety net.
