Ah, I see that now in that statement. He does not specifically claim his lendees are not invested in BS&T. Regardless of what Patrick claims, I still stand by the fact there was no common mistake on the premise only Patrick made the claim and that the depositor merely agreed that Patrick promised it, he did not also make the same claim, which would be required for a common mistake.
Patrick made an apparent logical argument. Patrick said he'd have enough equity to cover his loans in the event of a Pirate default
because his coins weren't deposited in BS&T. His only factual claim is that his loan portfolio wasn't in BS&T. That claim was *true*. Both parties made the mistake of concluding that this meant that the portfolio would have sufficient equity to cover a Pirate default. This wasn't due to any false claim but due to an incorrect chain of reasoning on which both parties *agreed*.
One can even argue that MP was in a better position to realize this problem than Patrick was. MP was specifically investigating the risk of indirect Pirate exposure. Patrick was not.
The doctor's lawyer seems to agree with me about common mistake in contracts because your doctor ended up doing the opposite.
There wasn't a common mistake in that case at all. The doctor represented that he had knowledge that I didn't have that led him to conclude that the insurance would pay for it. I had no way to check his reasoning. The point of that example is to see that you can't stop at the contract -- because my prior agreement with the doctor made me responsible for any costs the insurance wouldn't pay, his false representation (one I had no way to check nor any reason to doubt) damaged me.
This case is totally different -- Patrick substantially explained the reason he reached the conclusion he did, gave all the information needed to verify it, and she agreed with his reasoning even though it was obviously incorrect. The whole point of the discussion was for MP to protect against indirect Pirate exposure and they agreed that if that Patrick had no direct Pirate exposure, that somehow meant there was no indirect exposure.
