Worker's Compensation case back in the 90's/early 2000's. He was a Teamster and fairly un-educated (though he's smart, to be sure) who got hurt bad on the job.
To help him out, I basically was his attorney before the Workers Comp court. Mostly it was just writing all his legal document submissions (he doesn't type or use computers), but I even represented him once at a hearing before the Appeals Board ... with no legal training ... he was pro per and I was like 'Dad ... you better let me do this, cause you're way too pissed off ... plus you're on pain pills!'
Anyways, due to a glitch on their side, we'd ended up finding out what the Workers Comp Ins. Carrier's limits were on their policy with their Reinsurance company (think it was American RE Group or some such), and argued that they were failing to 'do what they were obliged to do under the law' on account of they'd reached the ceiling on their reinsurance ... i.e. they were trying to abandon my dad because of that fact.
It's funny to think that insurers buy insurance ... but they DAMN SURE do, and the limits on their policies with RE's are HUGELY important to them.
