I suppose what you are asking in essence 007, is, do Executive Orders of Governor's have the Force of law with civil or criminal penalties for non compliance??
This is a Public Health crisis, not an EO to postpone an election. A complaint in Mandamus was filed in Ohio with the OSC, concerning the Woods County election, under Original Jurisdiction, to void the EO. The WRIT was denied.
Even the Constitution permits the suspension of Habeas Corpus if the public safety requires it!
If you wish to file suit to block your Governor's EO, now is the time, not later. Be prepared to loose if you do.
The Right to assemble does not authorize spreading the Black death, if you will.
