Myfriend,
1) She’s not a lady acting as a judge, she’s a retired judge acting as an arbitrator. If, as a result of her gross negligence (which is what your accusing her of) she cost the plaintiff’s money that was rightfully owed them, I imagine she’d be open to being sued herself (although she’d probably win that suit). In any event, she’s not some actress they pulled off the street.
2) For the umpteenth time, she didn’t just determine that it wasn’t a $3000 wig, she also, at least claimed to know that it was a cheap wig. Georgi’s employees presumably are aware of the brands they sell, and while there is no such thing as wigmaker confidentiality in the law, even if there was, revealing that they don’t sell the wig in question wouldn’t violate it. Furthermore, it seems logical that the question she called Georgi with wasn’t “Do you sell this brand of wig?” but was the question she had left the room to ask, which was “Is it possible to repair this type of wig?” Why wouldn’t the employee be able to answer that question?
3) Assuming she just made the whole thing up, she has opened herself and the show up to quite slander suit from the couple once Georgi returns from France and confirms what you seem to think he easily can.
Let’s be dan l’kav zechus here, but you can’t just make stuff up in order to do so.
