PORTLAND, Ore. (KOIN) — Hundreds of people gathered at Pioneer Courthouse Square in downtown Portland to protest the decision to continue construction of the Dakota pipeline.

The previously scheduled rally happened to fall just minutes after a federal judge made his ruling.

The Associated Press reports the Standing Rock Sioux Tribe’s attempt to halt construction of the four-state Dakota Access oil pipeline near their North Dakota reservation was denied Friday by a federal judge.

The tribe had challenged the Army Corps of Engineers’ decision to grant permits at more than 200 water crossings for Dallas-based Energy Transfer Partners’ $3.8 billion pipeline, saying that the project violates several federal laws, including the National Historic Preservation Act, and will harm water supplies. The tribe also says ancient sacred sites have been disturbed.

U.S. District Judge James Boasberg in Washington denied the tribe’s request for a temporary injunction in a one-page ruling that included no explanation. It ordered the parties to appear for a status conference on Sept. 16.

Attorney Jan Hasselman with environmental group Earthjustice, who filed the lawsuit in July on behalf of the tribe, said in the days before the ruling that it’ll be challenged.
