The Supreme Court will consider eliminating the government's most potent weapon against racial discrimination at polling places since the 1960s. The court acted three days after a diverse coalition of voters propelled President Barack Obama to a second term in the White House.

With a look at affirmative action in higher education already on the agenda, the court is putting a spotlight on race by re-examining the ongoing necessity of laws and programs aimed at giving racial minorities access to major areas of American life from which they once were systematically excluded.

"This is a term in which many core pillars of civil rights and pathways to opportunity hang in the balance," said Debo Adegbile, acting president and director-counsel of the NAACP Legal Defense and Educational Fund.

In an order Friday, the justices agreed to hear a constitutional challenge to the part of the landmark Voting Rights Act that requires all or parts of 16 states with a history of discrimination in voting to get federal approval before making any changes in the way they hold elections.
