[Grammar] double negative

[xpert]

Aren't you not involved?

What does the sentence mean?
Is it considered a double negative question or what?
As far as I'm concerned, the sentence means are you involved?

Thanks a bundle in advance

It could be used when you're surprised to learn that someone is involved or you think that they shouldn't be involved. It's not the same as 'Are you involved' to me; it's more like 'Mind your own business'. ;-)
