German law firm TILP, which works exclusively on behalf of shareholders to bring “cost effective and procedurally efficient” class action lawsuits against major listed companies, has filed a lawsuit against EY over the auditor’s role in the multi-billion-euro Wirecard scandal.

The claim alleges that EY breached its duty to investors by “aiding and abetting” Wirecard in filing “false annual reports”.

The firm had filed individual lawsuits soon after the start of the scandal and has now been able to group them as a single case.

EY is weighing an appeal, as the tribunal had rejected previous attempts to bring a class action, stating that audits are not covered by the current class action procedure.
