McClure v Lam

The matter of McClure v Lam involved the applicant, McClure, seeking to set aside a subpoena issued to Lam, the respondent, which required the production of a large volume of patient records. The subpoena was intended to test the evidence of Lam’s usual medical practice. The dispute came before the Supreme Court of Victoria. The primary legal issue for the court was whether the subpoena, designed to test Lam’s usual medical practice, demonstrated a legitimate forensic purpose, and if the task imposed by the subpoena was oppressive due to the extensive number of patient records required for examination.

The court examined the principle that a subpoena designed to test the evidence of a practitioner’s usual medical practice generally serves a legitimate forensic purpose. However, the court also considered the proportionality of the task imposed by the subpoena to the apparent relevance and forensic need for the documents. In this case, the court found that while the purpose was legitimate, the extensive number of patient records required for examination due to the subpoena as currently formulated was oppressive. The court considered the task to be disproportionate to the forensic need, leading to the conclusion that the subpoena was oppressive.

Accordingly, the court set aside the subpoena, finding it to be oppressive. The court’s decision was based on the principle that the task imposed by the subpoena must be proportionate to the apparent relevance and forensic need for the documents. The court emphasised the need for a balance between the legitimate forensic purpose and the potential burden on the respondent in issuing a subpoena.

The final orders of the court included setting aside the subpoena issued to Lam, with directions for the parties to engage in further discussions to narrow the scope of the subpoena to a level that was both necessary and proportionate to the forensic needs of the case.
