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.
