Ok, that's totally different to what I thought you were talking about.
Is the lawyer acting on behalf of the patient? If this is being handled by a lawyer, they may be able to make an application and get a court order for disclosure. I'm not overly familiar with the particular circumstances that disclosures are allowed under the Privacy Act but generally speaking exceptions to confidentiality exist where:
- authorised by or under an Australian law or a court order
- disclosure is necessary to lessen or prevent a serious threat to the life, health or safety of any individual, or to public health or safety
- disclosure necessary to prevent unlawful activity, or misconduct of a serious nature, that relates to the entity’s functions or activities has been, is being or may be engaged
- reasonably necessary for the establishment, exercise or defence of a legal or equitable claim.
