Grammer v Johnson

Grammer initiated proceedings against Johnson in the Federal Court of Australia, seeking an injunction to prevent Johnson, who were Grammer's former solicitors, from acting for a current client in a matter that Grammer believed involved confidential information. Grammer argued that Johnson's potential representation of the current client could result in the misuse of confidential information about Grammer's financial position. The case required the court to determine whether Johnson could be restrained from acting for the current client based on the apprehension of misuse of confidential information, particularly given that Grammer had not provided any substantial instructions to Johnson for many years.

The legal issues before the court were whether Johnson's former status as Grammer's solicitor gave rise to a continuing duty of confidentiality, and if so, whether the apprehension of misuse of confidential information was sufficient to grant the injunction. The court had to assess the nature and relevance of the confidential information in question, considering the significant passage of time since Grammer last provided instructions to Johnson. Additionally, the court examined whether there was a reasonable apprehension that Johnson still possessed relevant confidential information that could be misused.

The court concluded that the duty of confidentiality did not continue indefinitely and that the apprehension of misuse of confidential information was not substantiated. The court found that any confidential information Johnson may have obtained about Grammer's financial position was over fourteen years old and that there was no evidence Johnson still possessed such information. The court also noted that Grammer had not provided any substantial instructions to Johnson for many years, which further undermined the argument that Johnson still held relevant confidential information. Consequently, the court determined that Grammer's apprehension of misuse of confidential information was not reasonable, and the application for an injunction was dismissed.

The court's decision was that Grammer's application for an injunction was unsuccessful, and no orders were made in Grammer's favour. The court found that the apprehension of misuse of confidential information was not reasonable, and Grammer had not established that Johnson possessed any relevant information that could be misused. The court dismissed Grammer's application, affirming that the duty of confidentiality does not continue indefinitely and is contingent on the ongoing relationship between the solicitor and the client.
