The primary person at fault is the umpire. Clearly. Secondarily, Weiters, and next Dusty.
The umpire should know the rule. Period.
Weiters, being a catcher, should know the rule. And apparently, he did, but he was bullied by the umpire into questioning his belief of the rule. Wieters should have told Dusty that he thought the umpire might be mistaken. We don't know whether he did.
Dusty, as manager, should have a command of the rules but it is understandable that he might be a bit fuzzy on some of the more obscure rules. It is also understandable that he believed that the umpire knew the rule. If Wieters had mentioned to Dusty that he thought the umpire was wrong, then Dusty for sure should have asked for a rule review. But we don't know if Wieters mentioned it.
If Wieters did mention it to Dusty, then Dusty becomes the primary. But we don't know.
