The Seventh Circuit held that a defendant's former attorney may testify for the government without running afoul of the Sixth Amendment. In the case, the defendant, who was incarcerated pending trial, mailed a letter to his attorney, marked "legal mail" to avoid its being opened by the authorities. The letter instructed the lawyer to forward an enclosed letter to the defendant's cousin. The lawyer read the enclosed letter, which instructed the defendant's cousin to come forward with a phony alibi to exonerate the defendant. Rather than comply, the lawyer sought to withdraw as counsel and turned the letter over to the government. The court held that the lawyer's conduct violated neither his ethical obligations (after all, the defendant was not seeking legal advice) or the defendant's Sixth Amendment rights (because the lawyer had withdrawn as counsel prior to testifying).
