The Texas Democratic Party has asked the U.S. Justice Department, Voting Rights Section, to retroactively approve its rules for apportioning delegates to the national convention. The 2008 rules were somewhat different than the 2004 state party rules, concerning delegates chosen by caucus. Texas Democrats used a hybrid primary/caucus system in 2008. The U.S. Supreme Court ruled in 1994 that the Voting Rights Act, section 5, covers political parties as well as governments. Section 5 requires that changes in election procedures (in some parts of the U.S.) must be approved by the Justice Department.
The Texas Democratic Party still does not concede that it needed to seek pre-clearance, but it has done so because of a federal court decision of August 25, called LULAC of Texas v Texas Democratic Party, issued by a 3-judge U.S. District Court in San Antonio.
