Alford v. United States

Background

The defendant was convicted in federal court for using the mails to defraud under §215 of the Criminal Code. At trial the government called a former employee who gave damaging testimony about the defendant in private conversations and statements to salesmen. On cross-examination the defense tried to ask where the witness lived; the trial court excluded that and later refused to allow questions about the witness being in federal custody. The Court of Appeals affirmed those rulings, and the Supreme Court agreed to review the case.

Reasoning

The main question was whether cutting off cross-examination about a witness’s residence and custody unfairly prevented the defense from testing the witness’s credibility. The Court explained that reasonable latitude on cross-examination is essential: asking where a witness lives helps identify the witness, locate independent testimony about reputation, and let the jury view testimony in context. The Court also said a defendant may try to show bias if a witness is detained or hopes for immunity, and that simply stopping inquiry into such matters can be an abuse of discretion. While judges may limit harassment or questions that invade self-incrimination, here the trial court improperly shut down relevant inquiry and thus prejudiced the defendant.

Real world impact

The Court reversed the conviction for this error. Trial judges must allow reasonable cross-examination to probe witness background and possible bias, including inquiry into residence and custody when relevant. The ruling emphasizes that summary exclusion of credibility questions can deny a fair trial; the Court did not decide other alleged errors raised in the petition.
