Even though he said he quit, his dues are still paid, he hasn''t left for displinary reasons AND since you are talking to him as a leader in the troop, then he is still considered by National to be active.
So since National considers him active, you can''t take his name off the charter. Come re-chartering time, mommy &/or daddy "re-ups" him by paying the fees, he would still be considered active.
Unless National clairfy''s the rule, that''s how it "could" be perceived, couldn''t it?
