Problem is, GAC does not really "oversee" ICANN decisions. It (sort of) participates in making them. That is inherently in contradiction to an oversight role. At the same time, it does a lousy job of participating in the development of ICANN decisions, because it is segregated from the other Supporting Organizations and has an advisory role. Not to mention the fact that governments as a group do not agree, they have different policies. So what is the status of a GAC "recommendation?" is it international law? does it have to be ratified by national legislatures? what if it contradicts one or more national laws?
