Who Runs This Place, Under What Authority?

There's a lot of discussion at Jeremy's blog about how to turn GFC into a body that actually exerts some influence on how the University is run.  This prompted me to re-read the Post-Secondary Learning Act to try to decipher which body or person has what authority (e.g., BoG, GFC, Senate, President, Chancellor, etc.).  Unfortunately, I could not make much sense of it.  Perhaps I just have not had enough coffee today, but this document seems deliberately vague, almost as if it were designed to fit whatever situation certain people needed it to do.
