Final answer:
The Supreme Court's ruling in Shelby County v. Holder did not give the Department of Justice increased oversight over electoral reforms in the states.
Step-by-step explanation:
The statement is False. The Supreme Court's ruling in Shelby County v. Holder actually weakened the Department of Justice's oversight over electoral reforms in the states. In this case, the Supreme Court struck down a key provision of the Voting Rights Act of 1965, which required certain states with a history of discrimination to obtain federal approval for any changes to their voting laws. The ruling effectively removed the Department of Justice's increased oversight over electoral reforms.
