A federal judge in New Orleans, Louisiana, has blocked a six-month federal moratorium on deepwater drilling in the Gulf.
Several dozen plaintiffs had sued President Barack Obama's administration, arguing the ban would create long-term economic harm to their businesses. Obama ordered the moratorium after the April 20 explosion of an oil rig off Louisiana that killed 11 people and triggered an underwater oil gusher.
White House spokesman Robert Gibbs says the government will immediately appeal the ruling to the 5th Circuit U.S. Court of Appeals.
"The president strongly believes, as the Department of Interior and Department of Justice argued yesterday, that continuing to drill at these depths without knowing what happened is - does not make any sense and puts the safety of those involved, potentially puts safety of those on the rigs, and the safety of the environment and the Gulf at a danger that the president does not believe we can afford right now," Gibbs said.
