Alright, so here is what I pulled up after doing some research: http://www.dph.illinois.gov/topics-services/diseases-and-conditions/diseases-a-z-list/coronavirus/faq#:~:text=To%20the%20extent%20individuals%20are,single%20household%20is%20prohibited.
This was last updated on 6/26/2020, so if your event was after that, you are allowed to host events of up to 50 people. The page doesn’t specify number of people per square foot either, so as long as your event had less than 50 people, they have no case.
If your event (hypothetically) had MORE than 50 people (which we know it didn’t), they still have no case, as they have to somehow prove that there were more than 50 people. Which is nearly impossible and even if it were, the cost of resources and manpower would vastly exceed the value of the ticket and even still, this would be a reject case by the DA. If not the DA, then any jury.
If the state’s position is that social distancing wasn’t maintained, then not only can you not enforce social distancing, but they have to PROVE that social distancing wasn’t enforced.
Either way, maintain your innocence and say nothing else.
If it makes it into court, they will try to offer you a deal. They do this with speeding tickets. I got a speeding ticket once and what I said when they tried to offer me a deal was “nope and we can go to court and then I’ll demand a jury trial and the cop either won’t show up, or you won’t be able to prove your case”.
I was told that they don’t do jury trials for speeding tickets…but that’s a lie and I had a printout showing that you can demand a jury trial for pretty much anything.
Court cases like these hinge on them getting you to admit guilt. The burden of proof makes cases like these extremely difficult to prosecute (unless it was something egregious, like 400 people in one venue).
Good luck, but you have nothing to worry about. I would even ask your attorney about the possibility of ignoring the cease and desist or having it thrown out, citing financial hardship!
