Republican lawmakers can say they were correct to focus on the new boundary lines just around the eight Senate districts initially declared unconstitutional.
The Florida Supreme Court ruled Friday that the Senates second attempt to redraw its political boundary lines is valid.
The decision means lawmakers with an eye on 2012 Senate contests can begin to crank their campaigns into gear. If the court had rejected the map, the justices would have overseen the drawing of new lines before the candidate-qualifying period in June.
