Notable Cases
DR & AJU successfully represented Samsung SDS Co., Ltd. in a lawsuit against the Republic of Korea to claim full compensation for providing service. Samsung SDS Co., Ltd. obtained and completed an order for the C4I improvement project from the government-affiliated Defense Acquisition Program Administration (DAPA). However, the DAPA refused to pay about KRW 7.4 billion (approximately USD 6.1 million), which is equivalent to the liquidated damages for delay in delivery. Accordingly, Samsung SDS filed a lawsuit against the Republic of Korea to claim full compensation for its services. In this lawsuit, fierce arguments continued over who was responsible for the delay in delivery. A detailed understanding of the C4I improvement project and the relevant technologies was required to evaluate the responsibility for the delay as a wide range of high technologies was integrated in the project.
DR & AJU proved in various ways that the reason for the delay in delivery was due to the complex contents of the project and successfully persuaded the Court that the DAPA was responsible for the delay. Although the Republic of Korea appealed, DR & AJU represented Samsung SDS in the appellate trial and prevailed in court on May 25, 2022.
