WASHINGTON (AP) - The Supreme Court appeared deeply skeptical
Tuesday about allowing states to sue electric utilities to force
cuts in greenhouse gas emissions from power plants.
Both conservative and liberal justices questioned whether a
federal judge could deal with the complex issue of global warming,
a topic they suggested is better left to Congress and the
Environmental Protection Agency.
The court heard argument over whether to end the lawsuit by six
states, New York City and three conservation groups against four
private companies and the federal Tennessee Valley Authority, the
five largest emitters of carbon dioxide in the United States.
The Obama administration has joined with the companies in asking
the high court to throw out the lawsuit. The administration says
EPA already is considering setting emission standards that would
accomplish what the states are seeking.
Why let the lawsuit go forward, when "the agency is engaged in
it right now?" said Justice Ruth Bader Ginsburg.
The lawyer representing the states acknowledged that the case
was before the high court at a "peculiar moment," but said the
court should block the lawsuit only if the EPA actually issues
regulations. In Congress, Republicans are leading an effort to
strip EPA of the authority to regulate greenhouse gases, but that
was not discussed at the court Tuesday.
No statute or rule "currently regulates the emissions of
existing power plants," said Barbara Underwood, the New York
solicitor general. Underwood said the plants operated by the
companies and the TVA account for 10 percent of all carbon dioxide
emitted annually in the U.S.
"This court should not close the courthouse door at the
outset," Underwood said.
Lawyers for the companies and the administration focused on the
enormity of the climate change issue to argue against the lawsuit.
"You have never heard a case like this before," Neal Katyal,
the acting U.S. Solicitor General, said. The term global warming,
Katyal said, "tells you all you need to know."
The case is the second climate change dispute at the court in
four years. In 2007, the court declared that carbon dioxide and
other greenhouse gases are air pollutants under the Clean Air Act.
By a 5-4 vote, the justices said the EPA has the authority to
regulate those emissions from new cars and trucks under that
landmark law. The same reasoning applies to power plants.
Ginsburg was among the justices in the majority in 2007. Two
others in that majority, Justices Stephen Breyer and Anthony
Kennedy, also expressed doubts about the states' case Tuesday.
Breyer questioned whether a judge even would have the authority
to issue the kind of order the states want.
Until now, pollution cases in the federal courts typically have
involved a power plant or sewage treatment plant that was causing
some identifiable harm to people, and property downwind or
downstream of the polluting plant.
Peter Keisler, representing the companies, said global warming
suggests a more complex problem in need of a comprehensive solution
that includes an evaluation of the "way we use and pay for
energy." Courts are ill-equipped to make that determination,
Keisler said.
The private defendants in the suit are American Electric Power
Co. of Ohio, Cinergy Co., now part of Duke Energy Corp. of North
Carolina; Southern Co. Inc. of Georgia, and Xcel Energy Inc. of
Minnesota.
Eight states initially banded together to sue. They were
California, Connecticut, Iowa, New Jersey, New York, Rhode Island,
Vermont and Wisconsin. New Jersey and Wisconsin withdrew this year
after Republicans replaced Democrats in their governor's offices.
Justice Sonia Sotomayor, who was on the federal appeals court
panel that heard the case, is not taking part in the Supreme
Court's consideration of the issue.
A decision is expected by late June.
The case is American Electric Power Co. v. Connecticut, 10-174.
