With your help, I finished my document, including the wording I struggled with. Thank you!
The question in the OP has been asked and answered. One of the things that makes the SDMB great is the discussions that spin off of OPs. I love that, and am not surprised it happened here.
To help with the spin-off discussion, I will create a completely contrived example that is sorta/kinda like the situation we are in.
We hired a special insurance broker. They agreed to find the best fit for our special insurance needs. They know our requirements and they know insurance companies. Based on their unique position of knowledge, they provided a recommendation.
Yes it’s was our choice to accept/reject the recommendation. So maybe we do bear part of the risk. But we relied on the expertise of the broker to match our needs. We did this because we are not insurance experts - the broker is. That’s why we paid them. We accepted their recommendation.
This is a special broker - it is unlikely a broker like this actually exists. We pay them a fee to do the research and we also pay them a marked-up premium. From the premium we pay the broker, the broker pays the insurance company’s premium, and the broker keeps their cut.
So after the broker has paid the premiums for a while, we then submitted a claim - uncontroversially covered by the insurance policy. We only then discover the insurance company is unable to pay the claim. They represented as an accredited insurance company specializing in the area we require. But unspecified circumstances have occurred after the arrangement was struck which prevented the insurance company from being able to deliver on the promise on paying this legitimate claim.
Now here’s the thing: the insurance company’s billing cycle is shorter than the broker’s. In other words, the broker has already paid the premiums. The broker has paid the insurance company for four weeks’ worth of premiums. The broker then submitted to us an invoice at the end of the month for their marked up total. While getting ready to pay the monthly invoice to the broker, we discovered the problem with the insurance company’s inability to pay claims. The thing that we are about to pay for is effectively non-existent.
So the situation is: We entered the relationship with the broker to pay them to handle the selection of the insurance company and to pay the marked up premium. The broker entered into a relationship with the insurance company to pay their premiums. When we tried to make use of the services of the insurance company, they failed to deliver. We then received an invoice from the broker for premiums. But we know the insurance company is not going to provide the services we need. So why should we pay, knowing this?
Our agreement to pay the broker was made in good faith that they would provide us with a qualified insurance company that actually meets our needs. The broker’s agreement to use this insurance company was based on the insurance company’s representations that they do this kind of insurance and pay these kinds of claims. We paid the broker to validate these claims.
I don’t know why the insurance company is unable to deliver on their promise. Did they rated us incorrectly? Did they let their licenses or permits lapse? Did they lie about being an insurance company at all? We don’t know. We trusted the broker to vet and background check the insurance company. That’s what we paid them to do.
Our position is, now that it is obvious to all that we are not receiving the service we requested, we should not pay. The fact that the broker has already paid is not our problem - cold but true.
This is, again, a totally contrived example. We do not have a broker nor insurance. But the spirit of the dispute is fairly close to these circumstances.
The bulk of the document describes how we know the insurance company failed to deliver. The part of argument implicated by the OP focuses on the fact that we agreed to pay the marked up premium in good faith that both the broker did their job in background checking the insurance company, and that the insurance company was able to meet their obligations. Now that one or both of these assertions is evidently not true, our good faith is challenged, and our agreement to pay is cancelled.
