Facts of the Case

James was a youth arrested for the murder of another adolescent. During his trial a witness testifying on his behalf described James's appearance on the night of the supposed crime. This description contradicted statements which James had made to police officers the day after the crime. To expose this perjured testimony, prosecutors moved to introduce James's statements into the trial even though they were obtained illegally.

Question

Could James's statements be used against him even though they were obtained illegally?

Conclusion

The Court held that the statements could not be used. Justice Brennan argued that prosecutors are allowed to introduce illegally obtained evidence when using it to impeach a defendant's own testimony. However, in this case, the Illinois Supreme Court wrongly expanded that practice making it applicable to all defense witnesses. Brennan concluded that this expansion "would frustrate rather than further the purposes underlying the exclusionary rule."
