A federal judge has blocked construction of the Keystone XL Pipeline, The Hill reports:

In a major victory for environmentalists and indigenous rights groups, Judge Brian Morris of the District Court for the District of Montana overturned President Trump’s permit for the Canada-to-Texas pipeline, which the president signed shortly after taking office last year.

Morris’s ruling repeatedly faulted the Trump administration for reversing then-President Obama’s 2015 denial of the pipeline permit without proper explanation. He said the State Department “simply discarded” climate change concerns related to the project.

The decision once again throws into doubt the future of the 1,179-mile Keystone XL, which for much of the decade since its proposal by TransCanada Corp. has been a lightning rod in national energy policy.

The Trump administration had tried to argue that federal courts didn’t even have the right to review Trump’s approval, saying that it extended from his constitutional authority over border crossings. The court rejected that argument.
