The U.S. Supreme Court called a district court ruling that upheld Alabama's redistricting plan, which overloaded some districts with black Democrats, "legally erroneous." In a 5-to-4 ruling, the justices rejected the ruling and sent it back to the lower court.
The Supreme Court hears a challenge Wednesday to Obama administration rules aimed at limiting the amount of mercury and other hazardous pollutants emitted from coal- and oil-fired utility plants. The regulations are being challenged by major industry groups like the National Mining Association and more than 20 states.
The regulations have been in the works for nearly two decades. Work on them began in the Clinton administration, got derailed in the George W. Bush administration, and then were revived and adopted in the Obama administration.
