Washington, D.C. The U.S Supreme Court Tuesday struck down a key part of the Voting Rights Act of 1965.
The court's 5 to 4 decision frees states with a history of racial discrimination from having to clear voting procedures changes with the federal government.
The restriction applied to all or parts of 15 states.
The vote does not invalidate the pre-clearance requirement altogether.
The high court ruled that Section 4 of the Voting Rights Act, the formula used to determine which states would be covered by the requirement, is outdated and unworkable.
Justices say it is now up to Congress to revise the law.
