We’ve reported before about the Keystone XL blockade activists, but the East Texans who own the land on which the pipeline is being constructed have been some of the project’s most vocal, if less-often-pepper-sprayed, detractors. And today they actually kind of won for a change.

A Texas judge has ordered TransCanada to halt work for two weeks on the pipeline, following a lawsuit from landowner Michael Bishop claiming that TransCanada lied about transporting crude oil when it’s really hauling tar-sands oil.

TransCanada’s all, “Oil is oil, what’s the big deal?” But the judge didn’t see it that way. From the Associated Press:

Tar sands oil — or diluted bitumen — does not meet the definition as outlined in Texas and federal statutory codes which define crude oil as “liquid hydrocarbons extracted from the earth at atmospheric temperatures,” Bishop said. When tar sands are extracted in Alberta, Canada, the material is almost a solid and “has to be heated and diluted in order to even be transmitted,” he told The Associated Press exclusively.
