Don Chisum on the CLS Bank case:
The Supreme Court often intervenes to resolve splits among the various courts of appeal. Here a split exists within a circuit that the circuit itself is unable to resolve. The circuit judges’ varying interpretations of a body of recent and not-so-recent Supreme Court precedent riddled with fuzzy language and inconsistent results caused the split. Now, the Court has the opportunity (and the obligation) to clean up a mess that is, to a major extent, of its own making.
