In Queensland, a shareholder with an equitable or unregistered interest in shares may bring or join a common law derivative action if the evidence sufficiently establishes their status as a shareholder, even if their name does not appear on the company's register of members. The purported rule requiring registration, traced to Maas v McIntosh (1928), has been rejected as lacking a satisfactory rationale and as capable of causing injustice. This applies only to the residual class of cases where common law derivative action principles still govern (principally unregistered foreign corporations).
