I just received this announcement via email, with a heading noting that Bert Rein will be arguing for Shelby County:

Hearing on Motions for Summary Judgment Scheduled for February 2, 2011 in Shelby County, Alabama v. Holder
Lawsuit Challenges Constitutionality of 2006 Reauthorization of Sections 4(b) and 5 of the Voting Rights Act
(Washington, DC) On February 2, 2011, arguments will be made in Shelby County, Alabama v. Holder (Case 1:10-cv-00651).
Date: February 2, 2011
Time: 9:30 AM
Place: U.S. District Court for the District of Columbia; Courtroom 8.
333 Constitution Ave. NW. Washington, DC.
The case will resolve the important question left unanswered by the Supreme Court in 2009 in Northwest Austin Municipal Utility District No. One v. Holder: whether Section 4(b) and Section 5 of the reauthorized (2006) Voting Rights Act remain constitutional more than 45 years after the statute’s original enactment.
