Okay, so I will again need attorneys to chime in, but I have a thought on some of what has confused me.
I just noted that the complaint does not seem to mention an outrageous standards violation in post #564. I have pointed out that the complaint does not mention the names of AOW dives that were supposedly being done and does not identify the standards violated for each one, especially the fatal dive. I have said I am confused because all of that would show how seriously standards were being violated. It finally dawned on me why that would be true. Maybe they do not want to emphasize that standards were violated.
To understand why, we need to go back a few years to another fatal dive, this one at a Boy Scout Camp in Utah, in which a boy scout died on a Discover Scuba Diving dive. In that case, PADI was also included in the list of defendants, but they got out of the case early, with the blame being placed squarely on the instructor and the dive operation. When they did, there was outrage, with plaintiffs and people supporting them (including on ScubaBoard) saying over and over and over that the instructor had not violated a single standard. In fact, it is hard to find a single DSD standard that the instructor did NOT violate. Because of their connection (which I still do not understand) to the instructor's insurance company, SDI/TDI went very public with their repeated claims that the instructor had not violated a single standard, so it was the PADI standards that were at fault. After a while, PADI published an open letter specifying a long list of standards violations, and I think that letter missed some. The instructor's performance was in the ballpark of this case in his incompetence.
So, in the Utah case, the plaintiff's attorney tried to keep PADI in as a defendant by pretending that the real fault in the case lay with PADI and its poorly written standards, not so much the performance of the instructor who was so understandably confused. Something similar might be going on here. If their complaint shows that the instructor clearly violated all sorts of standards, then the judge might wonder why PADI is being blamed for having unclear standards.
