Benjamin Cushing Duniway, United States v. Marshall — Opinion of the Court (1973)
“ Of equal importance with the duty of the court to see that an accused has the assistance of counsel is its duty to refrain from embarrassing counsel in the defense of an accused by insisting, or indeed, even suggesting that counsel undertake to concurrently represent interests which might diverge from those of his first client, when the possibility of that divergence is brought home to the court. ”
