All eyes were on a bland office building in the heart of Minnesota's capital city, where a meeting of five government regulators was about to begin.

Years of protests, rallies, legal fights, paperwork, public hearings and ad campaigns had led to this. 

Enbridge Energy wanted to replace its aging Line 3 oil pipeline to carry Canadian crude along a new route across northern Minnesota. 

Opponents urged the state to block the project, arguing it violates Native American rights, threatens the environment and is an unnecessary addition to a world that needs to move more quickly from fossil fuels to avoid a climate change crisis.
