A US federal judge has dismissed a case brought by California against six leading carmakers over alleged damage caused by cars' CO2 emissions. The legal action, the first of its kind, demanded millions of dollars in compensation from General Motors, Ford, Honda, Toyota, Chrysler and Nissan. But the judge ruled that the issue of whether carmarkers were accountable was a political, not legal, matter. http://news.bbc.co.uk/1/hi/sci/tech/7000457.stm Is this good or bad news??
