Interestingly enough, I've personally called for Bout Committee involvement while I was a referee in a couple of occasions.
1) It was around the time when I was just learning/experimenting with how to identify and assign fault in cause of corps-a-corps. I was given a basic "crutch" to use which was a great start since it covered most of the typical instances of corps-a-corps. It just so happened that the particular situation I encountered did not fall into such category. I used the same principle anyways to assign fault, and I made the call. Afterwards the penalized fencer and I exchanged a "No way... Can't be!" look. It was clear to all of us that my call just didn't make sense.
So I first established the facts of the matter as I saw to both fencers and coaches. Then I volunteered that I myself wasn't sure whether my application was correct or not. And I offered to get the Bout Committee to go over my ruling.
It turned out to be one of those situations where common sense should've overriden blanket directives. My mistake was quickly corrected right then and there, and we proceded with the bout.
By taking that step, I saved a lot of time and grief as a developing referee.
2) The other situation where I called for the Bout Commitee involvement is where I was 100% certain that I was correct. A bout had ended with a fencer crossing lateral boudary while near his end of the strip, and consequently being "artificially" placed on guard behind the rear limit.
The coach had never heard of such a rule, and the affected fencer (very young) was quite distraught. Emotional dynamics of the situation prompted me to go into customer service mode, rather than pushing for techinical/procedural correctness. I was way ahead in processing the DE bouts in my quadrant anyways.
So before the coach shifted into the appeal/argument mode, I postured that this was the correct application of the rule "as far as I understood it." But if he would like, I can hold off on this decision until we can verify this with the Bout Committee first (only two strips away). Of course, I knew 100% that the call was correct. But I opted for a customer service angle instead, and I acted as if I wasn't 100% sure and I would welcome a correction.
It turned out the gesture worked out great, and it defused the emotions very nicely, with the coach returning to hug the crying fencer and thanking me for the opportunity to verify.
