Also consider that YOU are not the arbiter of things for your booster club. Your booster club leadership is. That's why they have bylaws. Go back and read them, since they should have your answer there. If they don't have bylaws, you've got a bigger set of problems. Look into what other successful booster programs do and copy/borrow their bylaws.
Finally, punt this upstairs to your district office. Oversight of the booster program is not under your purview - it is theirs. They are DBA a group benefiting the school district, unless they have their own separate incorporation as a charitable entity, usually a 501c3. If they aren't, then your district can set whatever rules it likes. If they are, they are required by federal law to have election procedures for their leadership in their bylaws, which takes it out of your hands altogether.
tl;dr: Do things legally, and you won't have a problem.
: Good morning YB.
: Last night our boosters added a clause to
: the bylaws stating that aunts, uncles,
: grandparents, etc could be elected as a
: booster officer if their family member is a
: student in the band (Originally parents
: only, but we've had issues with people
: volunteering as officers in the past).
: One parent brought up if an older sibling
: wanted to serve as an officer would that be
: My personal feelings on this is that we
: should put an age minimum on it, at least 25
: if they're a sibling. My fear is a 19 year
: old brother of a student is now going on a
: trip with 18 year old girls.
: So two questions for you:
: First, do you allow older siblings to serve
: on your booster officer board?
: If yes, is there an age requirement?
