Although Dario Taraborelli has claimed that such Committee approval is required, he has refused to say where such a policy statement exists:

The only minutes I was able to find wherein the Research Committee discussed the possibility of reviewing and approving research, doing so was explicitly rejected, including by Dario, in favor of issuing guidelines instead:

At one point it included a proposal for a "Subject Recruitment Approvals Group" but that was removed in September 2010:
