Restraining A Solicitor From Acting For A Client: An Extraordinary Power With A High Hurdle

The New South Wales Court of Appeal has overturned a decision restraining a law firm from acting for a client, establishing that general observations of senior solicitors by junior lawyers do not constitute confidential information. The ruling clarifies when courts can invoke the extraordinary jurisdiction to prevent lawyers from representing clients and emphasizes that parties must be formally joined to proceedings that directly affect their rights.

In the recent decision of Solve Legal Pty Ltd v All is 1 Pty Ltd (t/as Banga Legal) [2026] NSWCA 55, the New South Wales Court of Appeal overturned a decision that had restrained a law firm from acting for a litigant.

The decision reinforces the fundamental principle that parties should be able to choose their own lawyers absent a compelling reason to the contrary and held that general observations of senior solicitors by junior solicitors will not be considered “confidential information.”
