The most potentially relevant is McWilliams v. Dunn, No. 16-5294, involves a question regarding the degree of independence needed for appointed mental health experts under Ake v. Oklahoma.
Then there are:
Weaver v. Massachusetts, No. 16-240: The defendant claims his lawyer was ineffective for failing to object to a closure of the courtroom during empanelment of the jury. Violation of the right to a public trial, when considered directly, is a “structural” error that is reversible without a showing that it actually prejudiced the defendant, but an ineffective assistance of counsel (IAC) claim requires a showing of prejudice under Strickland v. Washington. Does IAC require a showing of prejudice when the underlying error is “structural”? I believe Strickland is clear enough that the answer is “yes,” but there is enough of a circuit split for the high court to take it up.
