Here in the UK we always hear that an Old Firm move to the EPL would be blocked by UEFA & FIFA, and there are rules for leagues wishing to submit teams to the Champions League.

Alberta Amateur Hockey Association (AAHA) president Frank Drayton responded to the charges by stating that the Alberta league was one of few in the country operating as true amateurs, and attacked other associations, arguing that both Saskatchewan and Manitoba had submitted illegally professional teams to the Allan Cup tournament.

A school may submit multiple teams.

Clubs that do well in state titles submit teams for competition in national titles or "Aussies".

As in debating, this is also an inter-school competition, with Pimlico normally submitting several teams, and usually performing quite well with a good percent of their participants making it to state level qualifiers.
