Miguel Mejinez vs. Substance Abuse Treatment Facility, State Compensation Insurance Fund

The Workers' Compensation Appeals Board denied the defendant's Petition for Removal regarding an order that rescinded a prior directive for the applicant to disclose medical history under Labor Code section 4663(d). The defendant argued that section 4663(d) compels disclosure upon request and that they suffered prejudice from the applicant's refusal. However, the Board, concurring with the WCJ's recommendation, found that while section 4663 broadened the scope of discovery, it did not expand the methods of compelled discovery, which are limited to oral testimony and records under Labor Code section 5708. Consequently, the defendant failed to demonstrate substantial prejudice or irreparable harm necessary for removal, concluding that written interrogatories are not an appropriate method for compelled discovery in workers' compensation cases.
