Represented before the Supreme Court of Canada an accounting firm that was faced with a claim by a trust (through its trustees) for damages resulting from the bankruptcy of a holding company of which the trust was the sole shareholder. The Supreme Court upheld the decisions of the Superior Court and the Quebec Court of Appeal, and dismissed the lawsuit against our client. The Court reiterated that in Quebec civil law as in Canadian corporate law, shareholders do not have a right of action in respect of faults committed against the corporation in which they hold shares unless it is establish that they suffered a direct prejudice distinct from that suffered by the corporation, in relation to a distinct obligation (Brunette v Legault Joly Thiffault, s.e.n.c.r.l., 2018 SCC 55)
