The Florida Supreme Court says the Republican-led Legislature's do-over of the state Senate's redistricting map meets constitutional muster.

The justices on Friday rejected challenges by the Florida Democratic Party and a coalition of three groups that backed new anti-gerrymandering standards voters put in the state constitution two years ago.

They also turned aside objections from the National Association for the Advancement of Colored People.

The high court earlier affirmed the state House map but ruled the Senate's initial plan violated the Fair Districts standards in part by favoring incumbents and the GOP.

The seven justices were unanimous on most points. The high court's two black justices, though, dissented on one issue. They objected to splitting Daytona Beach's historically black community between two districts.
