Instead of calling him an ass, perhaps you should re-read the article.
He didn't sue his sister. He tried to get his sister's homeowner's insurance company to pay the medical bills. When they refused, he sued them.
If I were in the same position, I'd do the same thing. Instead of paying for a couple of thousand in medical bills, the insurance company now gets to dole out $122k. Serves them right.
I'll take your word for it.
It don't work that way. If he had tried to sue his sister's insurance company the judge would have thrown it out of court. He did not have any right to sue her insurance company, he did not have a contract with them. He sued his sister.
And the homeowner insurance company had every right to let him take it to court. Her homeowners insurance policy did not provide $122,000 in health insurance coverage. For the insurance company to pay any damages, the sister would have to have somehow been negligent. The court determined her to be negligent and now the liability insurance company is obligated to pay.
