The only possible difference I can see in the Northwestern case is that Discoveries was actually renting the facilities from the school district, not just using them by permission or "agreement" as in the other cases. Under the terms of a legal rental agreement, it could be that the property was considered the domain of Discoveries Soccer Club at that time rather than that of the school district, which would avoid the district facilities restriction.
Still, if this is the case, then if the 75% rule was not broken there should have been no violation at all...so why the fine?
