The US Supreme Court has taken up the cases of Burt v. Titlow from Michigan and Kansas v. Cheever.  In the both cases, the prosecution asked the high court to review a decision by a lower  court favoring the defendant.

Titlow is a federal habeas case involving issues of ineffective assistance in plea bargaining, a follow-up to last year's Lafler v. Cooper and Missouri v. Frye cases.  As with most federal habeas cases, there is also an AEDPA issue.

Cheever involves a claim of inability to form the mental state for murder due to drug use and the state's rebuttal of that claim with a court-ordered mental examination.
