I am a lawyer. I understand exactly how "agency" works. I can't emphasize how idiotic it is that you think that UM can excuse the conduct of a staff member on their payroll by saying, "well, he gave money to have third parties we weren't paying to do it for him" and because you haven't specified this exact scenario (which may or may not be true), you can't penalize us.
If you really think that, you are genuinely the dimwit I believe you to be.
For your information, "In law, agency is a legal relationship between a principal and an agent where the agent acts on the principal's behalf and under their control. The principal is liable for the agent's actions, which is known as the Latin phrase respondeat superior."
The idea that a governing body has to define every relationship, like "boosters," or else the relation can do whatever they please and not be held accountable is laughable. Not surprising that you don't understand that, dimwit.
