Hamlyn v Stanton (No. 2) [2020] NSWDC 633

Hamlyn v Stanton (No. 2) [2020] NSWDC 633

Dr Vaughan's opinions on urological clinical practice, referral to a radiation oncologist, preference for radiotherapy or conservative treatment, and the likely consequences of radiation oncology treatment were not shown to be within or substantially based on his specialised knowledge as a haematologist and medical oncologist, and were rejected. However, his composite summary of the medical records and some general explanatory matters, including the definition of PSA and certain informed consent matters, were admissible because they were within his qualifications or did not require the disputed specialist expertise.
