Take the example from this decision itself. The Department of Commerce issued a rule requiring certain fishermen to have federal observers on their boats and pay a fee. This decision was not made with any expertise and is not even the type of decision that can be made scientifically. It is purely a political decision that has nothing to do with any technical expertise. Yet the agency still argued it was unreviewable under Chevron.

It doesn't matter if the example is representative. It doesn't matter if it is 1%, 10%, or 50%. If agencies are able to act as a political branch and use Chevron as a cover to make these political decisions immune to judicial review, then the system is broken and needs to be fixed.

This is like defending qualified immunity for police by saying "well the arrests you presented where the police used the QI defense to cover over egregious rights violations are not a representative sample of all arrests made by the police."
