Trammel v. United States

Otis Trammel was indicted for importing heroin and conspiracy. His wife Elizabeth was an unindicted co-conspirator who agreed to cooperate with the government in exchange for lenient treatment. At trial, Otis invoked the spousal testimonial privilege to prevent Elizabeth from testifying against him. The trial court ruled that Elizabeth could testify to matters occurring after the conspiracy ended but not to confidential marital communications.

Chief Justice Burger, writing for a unanimous Court, traced the history of the spousal privilege from its origins in common law disqualification to its modern form. The Court reasoned that the Hawkins rule, which allowed either spouse to invoke the privilege, was sweeping and went beyond what was necessary to protect the marital relationship. When one spouse is willing to testify against the other, the marriage is likely already in serious trouble, and barring such testimony serves no legitimate purpose. The modified rule better balances the needs of the truth-seeking process with the goal of preserving marital harmony. The Court also noted the practical consequences: the old rule allowed a defendant to silence a willing witness and thereby suppress highly relevant evidence.

Trammel's modification of the spousal testimonial privilege has been widely followed and is now the majority rule in federal courts. The decision represents the Court's pragmatic approach to privilege law, balancing the interests of the marriage against the interests of justice. It must be distinguished from the confidential marital communications privilege, which protects the contents of private communications between spouses and can be invoked by either spouse.
