The U.S. Supreme Court won't take up a challenge to a Michigan law that allows the state to temporarily take away local officials' authority during financial crises and appoint an emergency manager.

The Supreme Court declined Monday to hear the case. Voters and elected officials were challenging a state law that says that to rescue financially stressed cities and school districts the state can reassign the governing powers of local officials to a state-appointed emergency manager. An emergency manager was in place during the water crisis in Flint.

Those bringing the lawsuit said emergency managers have been appointed in a high number of areas with large African-American populations but not in similar areas with majority white populations.

Lower courts said lawsuit was brought under a federal law that didn't apply.
