Background: In June 1906, E. L. Palmer sought medical care at Melbourne's Grand Hotel, initially under Dr. William Fox. Dr. William Moore, a surgeon, became involved when Palmer's condition worsened, sparking a dispute between the physicians. The Victorian Branch of the British Medical Association investigated, focusing on Dr. Moore's visit to the patient based on a friend's request. Dr. Fox accused Dr. Moore of attempting to supplant him and steer the patient to his hospital. Results: The Victorian Branch Council found that Dr. Moore, aware of Dr. Fox's care, visited without the patient's request. They concluded that, despite not being a "friendly visit," it was justified under special circumstances and did not aim to supplant Dr. Fox. Criticism arose for Dr. Moore's lack of professional courtesy in informing Dr. Fox. Dr Fox appealed to the Central Ethics Committee, leading to the reversal of the local decision and a debate on colonial branch autonomy. The Victorian Branch Council protested, claiming a breach of instructions. Despite prolonged proceedings, the local decision stood. Conclusions: Dr. Moore's 1909 resignation from the British Medical Association and subsequent rejoining underscored the lasting impact on his professional reputation, highlighting the intricate ethical challenges and appeals within the medical community.
