The Supreme Court struck down a key part of the Voting Rights Act Tuesday, but did not rule on two much-anticipated cases on gay marriage.
The Supreme Court has yet to decide Hollingsworth v. Perry, challenging California's gay marriage ban, Proposition 8, and United States v. Windsor, challenging the constitutionality of the Defense of Marriage Act.
The court is expected to announce the opinions Wednesday at 10 a.m., the last day of the court's session before it recesses for the summer.
The court invalidated Section 4 of the Voting Rights Act, the provision of the landmark civil rights law that designates which parts of the country must have changes to their voting laws cleared by the federal government or in federal court. The court said that Congress could create a new formula based on "current conditions."
On Monday, the court sent a challenge to the University of Texas' affirmative action program back to a federal appeals court.
