A lot, but the way it works is that in most cases, because creating commercials is a costly endeavour, advertisers will come, at the staff level, and seek a consultation. Then they will create the commercial after the consultation has been deemed to be consistent with the children's code. The finished commercial then goes to the committee. If the committee identifies any breach, if it's fixable, there are recommendations on how to fix it, and then it would have to get resubmitted and approved if the fix worked, or if it couldn't be fixed, it would just be rejected.
