Voting Rights Amendment Act of 2017 This bill amends various provisions of the Voting Rights Act of 1965, including by: (1) expanding the types of actions that would justify a court retaining jurisdiction to prevent a state or political subdivision from using new devices to limit the right to vote; and (2) imposing notice requirements on a state or political subdivision that makes changes to voting procedures, polling-place resources, or district boundaries. The bill also changes the calculation for determining whether a state or political subdivision is subject to preclearance requirements (i.e., requirements for certain jurisdictions to receive preapproval from the Department of Justice or the U.S. District Court for the District of Columbia before making legal changes that would affect voting rights).
