2. Whether the disposition is lawful;

A. The Plaintiffs’ assertion 1) Since chronic closed-end diseases were not cured, each of the instant dispositions is unlawful, notwithstanding the Defendant’s guidelines for handling chronic closed-end diseases whose primary quantity (FEV1) is less than 30%, regardless of the Defendant’s guidelines for handling chronic closed-end diseases. 2) The Plaintiffs trusted that they may continue to receive medical care after obtaining approval of the Defendant’s medical care plan prior to the enforcement of May 1, 2014, and that such trust is worthy of protection. Accordingly, each of the instant dispositions violates the principle of trust protection.

B. As to the first argument, Article 47 of the Industrial Accident Compensation Insurance Act and Article 41 of the Enforcement Decree of the Act provide that the Defendant may take necessary measures, such as examining whether the treatment plan submitted by an industrial accident insurance-related medical institution is appropriate, such as closing the treatment or ordering the reduction of the scheduled treatment period. Article 5 Subparag. 4 of the Act provides that “the treatment” refers to completely recovering from the injury or disease, or that the treatment cannot be expected any longer, and that the symptoms thereof become fixed. In addition to the above provisions, Articles 40 (Medical Care Benefits), 51 (Additional Medical Care) and 57 (Details of Disability Benefits) of the Act and its legislative purport.
