The competing views

What the available sources tell us about the request and the decision being challenged:

The challenge

The environmental challengers want the appeals court to review the federal agencies' pipeline-permit decisions.

The decision or response

The permits are agency decisions being challenged directly in the appeals court. The court's calendar does not explain the agencies' reasons or the challengers' detailed objections.

Based on the court’s case description and the filings identified below. Where a side’s detailed argument is unavailable, we explain the earlier ruling and say what is missing. Allegations are not findings of fact.
