coach's box

[Terrapins Fan]

We had a situation the other night, where the team bench chairs, were outside of the coach's box. There were four chairs outside of the box toward the mid court and the table.it is unclear who is set here presumably, the head coach and his assistants.

One of our officials always move the chairs back into the coaches box area as the other team did not have any chairs toward the mid court all their chairs were from the coach's box toward the end line.

The home team, who had the chairs toward the mid court, complains and wrote a letter to the Executive Board. They want to be able to keep four chairs outside of the coach's box for coaches. I've looked into the rulebook but can I find a rule saying they cannot have chairs outside of the coach's box. Thoughts?
