Golden Rule Insurance Company, Petitioner v. Todd Harper, Respondent

Summary

The Texas Supreme Court reversed the Court of Appeals’ grant of an anti‑suit injunction that barred the plaintiff’s Illinois declaratory‑judgment action, holding that the circumstances did not meet the “very special” threshold required for such injunctions. The Court reaffirmed that anti‑suit injunctions are appropriate only in four limited categories and that a single parallel or “mirror‑image” proceeding does not justify an injunction absent clear equity. Accordingly, the injunction was dissolved.
