In my country (not US), I’ve been given a summons by the court in order to appear for Jury Duty (and of course it’s mandatory to show up on the appointed date), but I have Autism (makes it difficult for me to interact with strangers and have distrust towards the authorities). I was last diagnosed when I was around 15 years old whilst the first was since 7.
The only thing I have that somewhat counts as medical proof as a psychological assessment on paper confirming I have Autism (as in on the spectrum) back when I was in 9th grade. Even if I waited through the jury panel, and for some reason the lawyer/s decided I should become a juror (despite not wanting to for medical reasons), could I use that as evidence?
However, will the judge accept that even though it’s an confirmed medical diagnosis from when I was a teen after pleading my case as to why I am ineligible to serve (difficulty on interacting with others, difficulties with understanding social cues or heightened anxiety), although even if excused: will that be considered permanent or temporary?
If your autism is severe enough that you would be unable to participate on the panel, it should disqualify you. But you would need to tell them that, and in the US you’d probably need to provide medical documentation of that.
Personally I live in a big city, and if you don’t want to do jury duty, they’ll dismiss you for any excuse. They have a large amount of people to pull from. My grandma (rural area) has had to do it multiple times despite serious excuses, presumably just because someone has to be there to form a panel.
