The Illinois GOP picked a losing argument to make which had nothing to do with Jacobsen. //

The difference in Pennsylvania was that the Plaintiffs there challenged the MANNER in which Gov. Wolf exercised his authority under police powers to curtail liberties protected by the Fourteenth Amendment. The Court examined the justifications and evidence which Gov. Wolf claimed supported the liberty restrictions in his Orders, and Judge Stickman found them to be insufficient.

The Illinois GOP did not ask the Court to do that — the Illinois GOP asked for an Injunction before any evidence was gathered on the subject of why/how Gov. Pritzker arrived at his decisions to impose lockdown conditions in the manner in which he did.
