US state lawmakers can redraw electoral maps to favour their own parties at any time, the Supreme Court has ruled.
By a vote of 7-2, the country’s highest court rejected claims by Democrats that Texas Republicans had behaved wrongly by changing boundaries in 2003.
Districts must be redrawn every 10 years to reflect population changes, but Republicans redrew the map a second time in a decade after taking power.
In a related ruling, the court said redistricting must not harm minorities.
Hispanic voters had said the 2003 redistricting did not protect them as required by the Voting Rights Act, and the court agreed by a vote of 5 to 4.
