NCAA Umpire Jurisdiction

[NSABlue]

I have a DD who plays DIII Softball at a College in Maryland(Currently ranked #2 in the latest NFCA Poll, sorry but had to brag a little) While playing a game at a conference opponents home field (Similar to any high school set up) the home plate umpire ordered all parents or fans who were wearing a team softball T-shirt out from behind the backstop because he said he considered them part of the team. All of the fans involved were parents of team members and had not said a word to any of the officials involved since the games had not even begun. The only set of bleachers at this particular field are behind the backstop. My question is, what does the NCAA rule book say about umpire jurisdiction here? Hopefully some of you who call NCAA ball can answer this.
