This is untrue in two respects:

1. Only a Pre-College Student can enter the question box. In many case it will be the student coach but an adult coach would have to send a student to ask a question.
2. Also, rulings are final so unless you can convince the ref that a field fault or ref fault that influenced the outcome of the match you're most likely out of luck. (A match will be replayed if such a fault is found.)

The Rule referenced in point 1 is T13.
