Strike participation does not negate unlawfulness of physical force used against a colleague in a work accident case.

The Supreme Court dismissed the cassation appeal, allowing the plaintiff's claim to recognize the incident as a work accident. The plaintiff, a doctor, suffered injuries while physically defending the hospital director against striking workers who entered his office to force his resignation. The court held that participating in a strike does not render the subsequent use of physical force unlawful, provided it was a sudden, external, and work-related cause. Consequently, the court ruled that the plaintiff's actions constituted a work accident under the relevant social insurance law.
