Supreme Court Blocks Environmental Emissions Standard

In a 5-4 split, the court ruled that the Environmental Protection Agency failed to factor in the full financial cost to industry of the changes.
The government has made several attempts to strengthen the Clean Air Act, but the court said this latest move must include costs as well as health risks.
Justice Antonin Scalia, writing on behalf of the majority, said the EPA "must consider cost - including, most importantly, cost of compliance - before deciding whether regulation is appropriate and necessary".
The objectors had argued that the cost of installing equipment to remove pollutants would have cost the power industry up to $9.6bn (£6.1bn) a year.
