Where criminal charges may arise, associate the police (and, when necessary, the relieving officer) with the case at once. If called by a police-constable, do not fail to note down his number (from his collar).
Decline to perform technical processes which are probably beyond your skill: thus the Coroner will usually secure the permission of the County Council for analyses in suspected poison cases.
Exclude lawyers and curious laymen, but invite another medical man, especially if your own previous actions may be in question.
Whatever you discover must be kept secret until you give evidence in court. As a matter of courtesy, the Coroner may be informed privately, before the inquest is held, of any unexpected or grave results; do not, however, inform press men.
Medical Examination of the Living and of the Dying, for the Purpose of Evidence.
All persons examined physically must be informed of, and consent to, the purpose and possible legal consequences.
Never take directions from a third person (e.g., police, magistrate, employer).
If a further examination may be necessary (e.g., under an anæsthetic), that fact should be stated.
Witnesses should be present, especially in the case of the examination of females.
Do not send written certificates to third persons as to the result of the examination, unless (1) In an open envelope, having read the certificate to the patient who takes it to its destination; (2) After having received the written consent of the patient so to do.
