Courts, in disregard of marital unity, have weakened this privilege in the past hundred years. Most notably, the [[U.S. Supreme Court]] in 1980 abrogated the centuries-old right of someone to prevent his spouse from testifying against him. ''See Trammel v. United States'', 445 U.S. 40 (1980). As a result, in federal court today someone is allowed to testify against a spouse if the witness wants to (or is compelled to by a grant of immunity). | Courts, in disregard of marital unity, have weakened this privilege in the past hundred years.
