What it's about

The Court overturned the lower court and sent the case back (reversed and remanded), ruling that the Natural Gas Act allows federally approved pipeline companies to condemn needed land owned by states or private parties.

The case concerned the balance between federal approval of interstate natural-gas pipelines and states' protection from private lawsuits.

Question presented

1. Whether the NGA delegates to FERC certificate holders the authority to exercise the federal government's eminent domain power to condemn land in which a state claims an interest? 2. Did the Court of Appeals properly exercise jurisdiction over this case?

What the Court decided

Holding

Section 717f(h) authorizes FERC certificate holders to condemn all necessary rights-of-way, whether owned by private parties or States. 938 F. 3d 96, reversed and remanded.
