I’m basing my conclusion on the type of lawyers who would take this particular case.
The vast majority of lawyers will take any case in their field that A, looks promising, or B, belongs to a deep-pocketed person who can afford the fees even if the case fails.
However, there is an elite group of high powered lawyers whose reputations allow them to pick and choose. They pick winnable cases, in order to maintain their formidable/lucrative reputations.
