In a fascinating, bizarre, only-in-America moment, a partisan majority of the Wisconsin Supreme Court has struck down the stay-at-home order issued by the Wisconsin Department of Health Services. There is no appeal to the U.S. Supreme Court from the state court's 4-3 decision, because it's based entirely on Wisconsin law. Although it probably won't be replicated in other states, the decision tells you a lot about the state of judicial politics in the U.S. today — and how those politics interact with the developing partisan politics of the coronavirus pandemic.
The majority opinion is lawyerly — not in the admiring sense of the word favored only by lawyers, but in the pejorative sense of the term favored by ordinary human beings.
To simplify only slightly, the Wisconsin DHS issued its directive to stay at home in the form of what it called an "emergency order." The state court held that it wasn't actually an "order" under Wisconsin law, but a "rule." According to the court, what made the emergency order into a rule was that it applied to the entire state.
Orders can be issued on an emergency basis by the Wisconsin DHS. Rules, however, need to go through a somewhat lengthy administrative process of information gathering and public discussion before they can be enacted. Needless to say, the emergency order didn't go through that process, which would have taken time.
The upshot is that, according to the court, DHS lacked the authority to issue the emergency order — and the order therefore lacked the force of law. Its criminal sanctions — a nominal fine or up to 30 days in jail for breaking it — were held to be invalid and the order was rendered unenforceable.
If this sounds crazy to you, that's because it should. No state could be so foolish as to deny to its public health officials the capacity to take emergency measures necessary to save lives in the middle of a pandemic.
And indeed, Wisconsin's laws aren't foolish. Wisconsin law says, among other things, that DHS "may authorize and implement all emergency measures necessary to control communicable diseases." It says that DHS "may promulgate and enforce rules or issue orders … for the control and suppression of communicable diseases." This statutory language makes it crystal clear that DHS can issue emergency orders as well as rules crafted under the required, lengthy administrative process.
For good measure, Wisconsin law also says that "any rule or order may be made applicable to the whole or any specified part of the state." That phrase pretty much rules out the majority's position that an order magically turns into a rule when it applies statewide.
