Pollution Case Could Be Headed to Tie in U.S. Supreme Court

The Hill reports on the oral arguments held in the U.S. Supreme Court Tuesday on the authority for the Environmental Protection Agency to regulate pollution that crosses state lines. The case could be tied because Justice Samuel Alito Jr. recused himself, leaving four justices each from "the bench's liberal and conservative wings," The Hill also reports. 

At issue is a rule by the EPA requiring 28 states to cut back on their coal-fired power plants that "'contribute significantly'" to the air problems in other states, The Hill also reports.
