[Grounds for recognition] A.1-4 Evidence, the purport of the whole pleadings

2. Issues and judgments

A. The Plaintiff’s completion of the design service business is recognized, but the key issue of the instant case is whether the due date for the payment of the service arrives.

B. The Plaintiff asserts that all design services are performed, and the “the time when approval of the use is completed” under the service contract refers to the time when the authorization of the project implementation is given, and the deadline for performing the service payment has arrived.

On the other hand, the defendant asserts that since the meaning of "the time when approval of use is completed" refers to the time when redevelopment project is completed and the final completion is completed, the part of KRW 3 million is not due.

(2) The preparation of the design documents that the plaintiff has received is submitted at the time of application for authorization for project implementation and is not submitted at the time of execution process or completion.
