THE EFFECT OF ENFORCING THE PRIVILEGE.
The courts are not warranted in admitting incompetent evidence in order to prevent the failure of justice by the exclusion of the privileged testimony. A letter written by a physician is inadmissible as evidence of the privileged facts which it states;[461] and a certificate of the cause of death, required by law to be signed by the physician and filed, is not admissible to prove the cause of death in an action in which the physician cannot testify.[462]
The making of the objection does not raise a presumption against the person making it.[463] In Iowa it has been held that the patient should not be interrogated under oath as to whether or not he will waive his privilege, for the jury ought not to be prejudiced against him by any show of reluctance.[464] In Michigan, however, it has been held that a patient’s failure to produce his physician as a witness is a legitimate fact for the jury to consider.[465]
