Thank you for this example - is very interesting. I read the Wikipedia article [0] and I would point out that a class defined by birth place would pass easily Scalia's test for commonality. So it seems that using a class action suit that includes every person born in US of un-documented parents would work. (But who knows what other tests the Supreme Court would come up now...)
