"In so doing, the high court on Tuesday unanimously rejected industry arguments that officials must balancecompliance costs against the health benefits of cleaner air. The ruling was a major boost for the federal Clean Air Act. It said the law does not require the government to consider the financial cost of reducing harmful emissions when it sets air-quality standards. The justices also ruled against industry arguments that the Environmental Protection Agency took too muchlawmaking power from Congress when it set tougher standards for ozone and soot in 1997. "
