THE RULE IN THE UNITED STATES.
It is to be assumed, in the absence of statutes varying the rule, and of decisions to the contrary, in the several States of the United States, that in those States which derived their law from England the same rule of evidence obtains as that above enunciated. But many of the legislatures have by statute extended the privilege to communications between physicians and their patients, as well as to other specified confidential communications which it does not fall within the scope of this work to discuss.[216]
States and Territories in which there are No Restrictive Statutes.—The following States and Territories have no statute restricting the nature of the disclosures which a physician may be compelled to make in a court of justice: Alabama, Arizona, Connecticut, Delaware, District of Columbia, Florida, Georgia, Illinois, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Mississippi, New Hampshire, New Jersey, New Mexico, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Vermont, Virginia, and West Virginia.[217]
States and Territories in which there are Restrictive Statutes.—The following States and Territories have statutes restricting disclosures by physicians: Arkansas, California, Colorado, Idaho, Indiana, Indian Territory, Iowa, Kansas, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, South Dakota, Utah, Washington, Wisconsin, and Wyoming.[218]
The Rule in United States Courts.—In trials at common law in the courts of the United States, the laws of the several States, except where the Constitution, treaties, or statutes of the United States otherwise require or provide, are regarded as rules of decision.[219] Section 858 of the Revised Statutes of the United States prescribes rules with reference to competency notwithstanding color and interest of witnesses, and in actions by or against executors, administrators, or guardians, and then provides that “in all other respects the laws of the State in which the court is held shall be the rules of decision as to the competency of witnesses in the courts of the United States in trials at common law, and in equity and admiralty.” Accordingly it has been held by the Supreme Court of the United States that in an action in the Circuit Court of the United States for the Southern District of New York, on a policy of life insurance, the evidence of a physician, inadmissible under Section 834 of the New York Code of Civil Procedure, was properly excluded.[220] But in criminal prosecutions in United States Courts, the privilege secured by State statutes does not avail.[221]
