I think you're referring to this:
Yesterday, in another thread, Bill Pitcher wrote:Here is a question: We have a scout who taught Swimming and Canoeing MB's at summer camp. He signed off the requirements and the Waterfront Director signed the Blue Cards and returned them to the SM. Can that boy still sign off requirements for these MB's, including the swimming requirements for rank, for the troop, even though he is 17?
He said the Blue Card was signed by the waterfront director, who is presumably an adult, though the 17-year old attested to the boy's having met the requirements. Camps are often merit badge mills, whether or not the requirements are being signed off by older youths.
There are protocols for the MB's and they're the requirements. There are certain others pertaining to MB counselors, such as YPT, minimum age, some level of expertise in the subject matter. As for the rest, well, some of it has to be left up to the individual, and that's what leads to such lively discussions here. You mention the Blue Cards, and the concensus here is that they are not required. The MBC could sign on a cocktail napkin that the scout earned the MB and it would be okay. For group MBs, the saying holds - "teach in a group but test individually." Most of what you read here is people griping, er, pointing out that this does not always occur.
I think that for the most part the right hand does know what the left hand is doing. It's just that in many instances neither hand is following the prescribed protocol.
