Kingsnorth Case. worth a perusal of the link.

By a majority verdict, a British jury found five protestors who shut down the Kingsnorth coal-fired power plant had a “lawful excuse” to close the plant to prevent greater damage from global warming. Greenpeace activists, protesting the contribution of coal-electric power plants to climate change, scaled a chimney and painted the word “Gordon” on the chimney before they were forced down (“Gordon” is a reference to British prime minister Gordon Brown). The protest shut down the power plant temporarily and the graffiti cost about $62,000 to remove. The jury verdict in favor of the protestors illustrates how a U.S. jury might respond to similar protests.
