I just read through the decision:
http://www.supremecourt.gov/opinions/15pdf/14-723_1bn2.pdfLong story short, the case is about the contract between the insured and his company. This really won't have much impact beyond this case. In short, the injured party here had injuries that required surgery to the tune of approx $1120K in medical expenses, paid by his insurance company. He sued and was awarded around $500K. His lawyer took around half. His insurance company, consistent with the policy, issued a demand for their $120K to their client. He refused, and hired another lawyer to work the case and try to settle with the insurance company. (Note that the $250K was being held in escrow at this point.) This lawyer negotiated, gave the insurance company a deadline to respond, and when they didn't respond, he turned the funds over to the insured. Company then sought to collect again. Insured said the money is gone, paying the second lawyer and for life expenses. So, the insurance company sought to attach all of the insured's assets and personal property for their reimbursement claim. Case went through the courts, and SCOTUS has said that under ERISA - Employee Retirement Income Security Act of 1974 - the insurance company can only attach the funds from the PI case, but not all of the insured's assets. This is in no way anything new. One commentator said this opinion would win the award for the "case that breaks the least new ground."
Takeaways? First, it doesn't mean that insurance companies can't pursue a claim to recover, it only means that the pool of assets available for that recovery attempt is limited to the award itself, and not the insured's general assets. And, this seems like common sense to me, but common sense and the law don't always agree.
Second, you've got to know your policy. It is, after all, a contract with the insurance company. If it says that they can take some of what you recover in a PI suit, then you're stuck with that. While Rev has a point about the insurance company riding on the back of the insured to seek recovery, if the contract doesn't say so, then you're out of luck. Yeah, you could hire a lawyer to fight/negotiate, but that may end up being counterproductive.
Third, some insurance companies do seek to get involved, real early in the process. I know that a few years back, I fell at home and broke my hand. Got it treated, and then got a call from my medical insurance company a week or so later. They wanted details as to when and how the injury occurred. In the course of the conversation, the claim specialist told me that they were looking for liability on the part of someone other than me or my wife to seek recovery of expenses.
Fourth, and this may just be me, but it seems like in the case upon which the OP is based, the lawyers were the big winners here, and that surprised me. The case resulted in around $500K being awarded to the victim. Half of that went to the PI lawyers. When he then fought the insurance company (the first time), he ended up paying another lawyer a big chunk from the settlement. He then paid another lawyer fee for the fight all the way to SCOTUS. I'm guessing here, but I'd imagine that this fight cost him well beyond the $500K he was awarded. My surprise? Well, I guess I'm ignorant to the costs of civil litigation, but I had a hard time believing that half (actually 52%) was earned by the trial lawyers. Second, I can't fathom how the second lawyer ate up more than a few thousand to make some phone calls and write letters to the medical insurance company. Again, I'm ignorant to civil litigation expenses. But the real shame here, at least for me as a lawyer, is to see this injured guy end up paying more than he took in just to exercise his rights to seek compensation. I know tort reform is a hot button topic, but maybe lawyer fees need to come up in that discussion.
