What it's about

The Supreme Court rejected the Ninth Circuit’s interpretation, wiped out its ruling (vacated it), and sent the case back to the lower court (remanded it).

The Alaska National Interest Lands Conservation Act (ANILCA) was the law at issue; the dispute focused on Section 103(c) and nonfederal land within Alaska park boundaries.

Question presented

Does the Alaska National Interest Lands Conservation Act of 1980 prohibit the National Park Service from exercising regulatory control over state, Native, corporate, and private Alaska land physically located within the boundaries of the National Park System?

What the Court decided

Holding

The Ninth Circuit’s interpretation of Section 103(c) is inconsistent with both the text and context of ANILCA. 768 F. 3d 1066, vacated and remanded.

Result
Vacated

The Court's reasoning

The Court said the Ninth Circuit’s reading of Section 103(c) conflicted with ANILCA’s text and context.
