The way I thought it came about,

During the Spring Swap meet the state tried to shut them down,

But just before the Judge was to hear the case Carlisle came to an agreement with the state which allowed the shows for this year

With the safety measures they already had in place, the acreage that the show was spread over
and what the news made it sound like the Judge was going to rule against the state , guess the state didn't want a ruling against it self and there rules
which would have made it easier for other businesses to open

Interesting that the state kept it secret

Guess they didn't want others working out a deal also
