The short answer is, yes, though the majority is more wrong.
In fact, the issue in Michigan v. EPA seems so simple that the MATS rule could have been affirmed in a two-page opinion. Judge Scalia notes that the word “appropriate” – on which the entire 44 pages of the majority, concurring, and dissenting opinions focus – is “capacious”. I agree. If so, and if Chevron means anything, “appropriate” is surely capacious enough to allow for an interpretation that does not include cost considerations. That should have been the end of the case.
I do feel compelled to note, however, that Justice Kagan’s dissent also got it wrong, in at least three ways:
- I think she’s flat wrong to suggest that, because the MATS “floor” is based on the top 12% of facilities already in operation, that means that establishment of the floor already takes cost into account. As Justice Scalia cogently notes, those existing facilities may well have been under their own regulatory duress – a duress that may not have considered cost.
- Justice Kagan confuses cost-benefit analysis and cost-effectiveness analysis. For any given goal sought by EPA, the various options provided by the MATS rule may allow power generators to attain the goal in the most cost-effective means possible, but if even the most cost-effective approach were to yield $10B in costs and $10M in benefits, that would fail the cost-benefit test for most people.
- Finally, and most importantly, Justice Kagan got the consequences wrong. Instead of suggesting, as she did, that the majority decision
deprives the American public of the pollution control measures that the responsible Agency, acting well within its delegated authority, found would save many, many lives,
she should have made the point that the majority decision will have no impact on EPA or the MATS rule. The Supreme Court did not vacate the rule; it merely remanded the rule to the Court of Appeals. Justice Kagan’s position should have been that EPA still has sufficient discretion, even on the existing record, to defend the MATS rule within the confines of the majority opinion. Instead, Justice Kagan gave ammunition to those who oppose the rule, by suggesting that it cannot be saved.
A pox on both their houses.
