Charges dropped against climate activists who tried to shut down pipelines

Seattle residents had hoped to use 'necessity defense' in Minnesota court, arguing threat to planet was so great they had no choice

A Minnesota judge abruptly dismissed charges against three climate change activists during their trial on Tuesday, saying prosecutors had failed to prove that the protesters' attempt to shut down two Enbridge Energy oil pipelines caused any damage.

The Clearwater county district judge Robert Tiffany threw the case out after prosecutors rested their case and before the protesters could use their defense: that the threat of climate change from using crude oil drilled from Canadian tar sands was so imminent that the activists' actions were not only morally right, but necessary.
