On diversity jurisdiction and national banks

SCOTUSBlog has this post on the national bank / diversity jurisdiction case, on appeal from the Fourth Circuit, to be argued tomorrow in the U.S. Supreme Court. The issue is "whether, for purposes of diversity jurisdiction, a national bank is considered a citizen of every state in which it maintains branches, even when its main office is in a different state." The Fourth Circuit said yes, Wachovia is arguing no, and is supported by the Solicitor General's office.
