The Act gives the Department of Justice the power to approve or reject any change in a voting law in certain districts where less than 50% of the population were registered to vote in 1964. The Act also outlawed literacy tests that once limited the right to vote in some areas to those who could read the ballot, as well as so-called "Grandfather Clauses". | The Act gives the Department of Justice the power to approve or reject any change in a voting law in certain districts where less than 50% of the population were registered to vote in 1964.
