I have to admit that I'm not sure I know the language of the oath you're talking about.
I do know, following our work on ArriveCAN, that in the first report we issued on professional services, which included contracts on McKinsey, there was a requirement added that someone in the procurement process needed to attest that they knew all of the rules they needed to follow and that they had followed them.
That's a good reminder, but in my mind, it's just another step. I really do think that it's time to decide whether there are too many rules, because after my audits or internal audits or third parties or the ombud's work, more rules are constantly added, and eventually it just becomes too much for people to be able to apply them with due diligence.
