Probably depends on the state, but they can certainly haul you in for failing to appear where I am.

I’ve been summoned 4 times for county court in 3 different states. The first summons I got to reject because I was moving to another state prior to the court date. In the second state I got called in for the pool, and had to go in for a few days if I remember correctly, but never made it to the courtroom. In my current state I’ve been called in twice. The first time I went in for one day, and was dismissed some time early or mid afternoon having not been called to the courtroom. The second time which was this year, I was called into the courtroom and got to see the jury selection. I was in the group of backup jurors, and since there were no issues with the jurors in the box I got dismissed before noon. I don’t know if I would have made it through selection as I would have told them I have adhd (I brought my diagnosis paperwork with me). I would have tried my best if selected, but with the executive function and auditory processing issues I may not be the best suited for it. I would like to serve on a jury at some point, but would prefer for it to be when my kids are a bit older

When you do get called up and go in, there will likely be a period of time that you can’t be called up again for
