WASHINGTON (Reuters) – In two cases that could reverberate through U.S. politics for years to come, the Supreme Court is set on Tuesday to hear arguments over the contentious practice of manipulating electoral district boundaries to entrench one party in power.
The justices last year failed to deliver a definitive ruling on the legality of the practice, called partisan gerrymandering. They will get another chance in cases challenging North Carolina’s Republican-drawn statewide U.S. House of Representatives map and a single Democratic-drawn House district in Maryland.
How do federal judges have the right to overturn what legislatures have done? They are not elected by the people. State judges might as they are voted into office.
Legislative districts across the country are redrawn to reflect population changes determined by the federal census each decade. In most states, redistricting is done by the party in power, though some assign the task to independent commissions in the interest of fairness.
