A federal judge's ruling has temporarily blocked the Trump administration's plans to open up a large swath of Alaska's National Petroleum Reserve for natural gas lease sales. The ruling preserves a land agreement known as the Nuiqsut Trilateral right of way, which gives local Native residents some control over oil development in about 1 million acres around Teshekpuk Lake.

Why it matters

The National Petroleum Reserve is a vast, ecologically sensitive area in northern Alaska that has long been the subject of disputes over oil and gas development. This ruling represents a victory for Native groups seeking to limit drilling in their traditional lands and preserve the environment, at least for now.

The details

U.S. District Court Judge Sharon Gleason ruled that the Nuiqsut Trilateral right of way agreement "shall remain in full force and effect," preventing the Trump administration from including that acreage in an upcoming lease sale planned to span 5.5 million acres. The administration had previously canceled the right-of-way agreement, prompting a lawsuit from Nuiqsut parties.

  • On Monday, March 16, 2026, Judge Gleason issued the ruling preserving the Nuiqsut Trilateral right of way.
  • The U.S. Bureau of Land Management was originally planning to open bids for the 5.5 million acre lease sale on Wednesday, March 18, 2026.

This ruling represents a victory for Native Alaskan groups seeking to limit oil and gas development in sensitive ecological areas of the National Petroleum Reserve. It highlights the ongoing tensions between energy interests and environmental/indigenous concerns in the region.
