This reminds me of my most glorious case. A local fellow in Florida had been sent the wrong version of an SPD for a welfare benefit plan, after he had asked the HR department to send him an SPD. It said he would get a benefit if he met "X" conditions described in the SPD. So he quit, relying on the fact that he had met those conditions. His claim for benefits is denied. "But lady..." he says. -- "Sorry, bud, that's not what our SPD says", they say. "But mine says..." he protests. -- "Well, that's not the current version. You're looking at an old version" they respond. -- "But lady, then you must have sent me this old one when I asked you to send me an SPD, just before I quit in reliance on what I had read in the booklet." HR responds, "I don't think that happened, sir. You must have had an old version already that you got mixed up, and, frankly, we can't honor your claim because we would be vulnerable to fraudulent claims by people who say they are in a similar situation. You'd need to be able to prove that you were sent the old version."
He comes to see me. I meet with him, take the stamped envelope in which the SPD came, hand-addressed to him by the HR department. I tell him this will be a tough one, and I'll get back to him. I write a long letter to the plan administrator, complete with the law on detrimental reliance (which basically shoehorns these claims into an "interpretation of the plan document" theory -- which is weak, but it often worked, ironically due to an SPD case I had argued and won in the Eleventh Circuit, which I "mentioned" in my letter). I get a response that's basically what he had been told, again saying the plan formerly included the conditions he says he's relying on, but frankly they can't honor a possibly fraudulent claim and there's just not enough evidence here for the plan administrator to grant the claim. A few days later, I'm looking at the file again. The sunlight from my south-facing window catches the shiny cover of the SPD. I tilt the booklet at an angle and behold -- I see an impression of the client's name and address, essentially embossed in the shiny cover of the SPD. The person in the HR department had used a ball-point pen that had pressed through the envelope and onto the SPD cover, where there was an exact copy of the name and address that had been written on the date-stamped envelope. So the envelope matched the SPD, proving the old version had been sent to him on the date of the postmark on the envelope. I write to the plan administrator and tell them what I've discovered. They grant the claim.
I should find the 20-year-old file and confirm that I'm remembering all the facts accurately, but this is the gist of it. Or how I want to remember it, anyway ?
The client was enormously grateful, and the "extra" benefit made a huge difference in his quality of life.
