Due to recent incidents, a few people were discussing the legality of banning the use of certain KO cubes in a competition if a sponsor wished. The question that needs to be answered is: could an organiser ban the use of a particular brand of cube (obviously I'm talking about the GuHong 3x3) to comply with the wishes of a sponsor (or just for the sake of it)?
A few things that were brought up in the discussion:
Regulation 2a2 states that: Any person may be a competitor during a competition, if he: meets the competition requirements, which must be clearly announced before the competition.
Could a requirement be no KOs?
3m) All puzzle and puzzle part brands are allowed, as long as the puzzles comply with the other WCA regulations.
Does 2a2 overrule or is it irrelevant?
And for some reason this regulation still exists:
8c) A closed competition may be open (courtesy of WCA Board) to: persons with a specific nationality. No other distinctions are allowed to declare a competition closed.
Does excluding certain brand of cubes count as closing a competition (thereby ruling it out as a possibility)?
Peoples opinions would be nice, but really I would like a solid answer to this question.
Obviously this would only be an issue if the situation actually occurred, and I would think that most delegates would tell the sponsor to put up with it or go away, but I cannot guarantee this and an answer to this problem would ensure no issues of this sort occur.
