Unless you're saying Dimension didn't know that Simpson retained the code. Which is a funny thing to say because it's not what you said in your claim. You're not seriously suggesting that Dimension didn't know that Simpson had the code until after 2010?
But this is all angels on the head of a pin stuff. I'm with Mike1991 and Duedilligence3. While you argue about things that happened when Heck was a pup, the world moves on.
I think I'm going to drop your course professor. Nothing personal but I think I could probably learn more from another instructor. You seem to be saying that when a person signs a contract but allegedly violates it, the remedy isn't breach of contract but fraud. It's an unusual suggestion. And I still don't understand why you say this purported breach of contract makes Tmmi a thief. I keep flipping thru the textbook and find nothing like this in there.
I don't feel your creativity will serve me well, and I think I need to seek out a more orthodox teacher.
