Also http://law.stackexchange.com/questions/940/is-there-a-prefer... kinda back's this up alas.
Maybe somebody else knows one, but as I stated, I have personally used this law in comparable circumstances and aware others have. But without the ability to lookup such cases on a non-paywall site then alas we have hit an enpass.
So unless you are able to link such a site then your not helping at all.
You are right, we are not helping at all with proving your unsubstantiated claim.
More evidence would be preferred, and would definitely raise my trust that there wasn't some mistake of memory, but it seems a bit extreme to dogpile on someone who is stating what they believe as fact from personal experience, and when asked for verification seems willing to try to find that but without the knowledge or ability to do so and asking for pointers on how to do that.
Asking as I'm aware of a couple of cases with friends in the past few years. Personally had one case in which was about to go to SCC regarding software update removing some functionality and the company settled out of court and left me most happy with the settlement.
