UK-listed online gambling operator 888 Holdings says it will appeal a court ruling barring online casino operators from dealing with German customers.

Last October, a Federal Administrative Court upheld a lower court ruling in the state of Baden-Württemberg that barred international gambling operators not holding a German license from offering their services to local gamblers. Last month, 888 warned investors that it might have to quit the German market, which represents a significant chunk of 888’s overall revenue.

On Monday, 888 announced that its German-facing subsidiary had filed a constitutional complaint with the Federal Constitutional Court based on the company’s assertion that the October ruling “infringes its constitutional rights, as well as its rights under [European Union] law, (including the freedom to provide services), and hence should be reversed.”

While the market reaction to 888’s original German exit announcement was alarmist, investors shrugged at this latest announcement, as the company’s stock closed out the day’s trading down less than 1% to 266p.
