In our district, which runs all boards for the district, our coordinator goes over everything with a magnifying glass before even thinking about the review board. Once a board is scheduled, he has a check list that is used with the scout to try and make sure he comes totally prepared. One of the things on that list is complete uniform, including pants.
And herein lies many of the problems. Requiring a full uniform at an EBOR is adding to the requirements the same way requiring minimum hours for an ELSP is adding to the requirements. There is nothing wrong with going over everything to make sure all the paperwork is completed correctly but adding to the requirements is wrong.
