Here's an article that argues the aunt who sued her nephew is actually a fine, upstanding individual who just wanted to bilk her relatives' home-owner's insurance.
I don't actually think it's commendable to sue your nephew to get to deeper pockets. If the problem is her health insurance, as claimed, then either the health insurance provider violated your policy and should be sued or you need to get a better policy for the future. But paying low premiums for inadequate insurance and then suing someone else when the inadequate insurance proves inadequate is not honorable behavior.
On an unrelated note: here's a terribly sad photography project of what people look like when they use technology to disengage from the people around them. I want to get a print framed of the picture of three kids sitting lined up on the couch.
