I think Relic don't often read our Threads on this page, so I made a post in their forum.
https://community.companyofheroes.com/discussion/243043/question-about-terms-and-conditions-of-tournament#latest
After 12 min i got a response. Not from Relic, but from a mod, who locked down my thread.
"First: I do want to make clear that I do not speak for Relic or SEGA for this paragraph. According to my understanding of the political situation, The Russian Federation is not a sanction country. There are indeed sanctions in place due to the Crimea incident, but according to the most up-to-date list that you provided, the sanctions are against specially designated nationals of of Ukraine or Russia, but not a country sanction. Therefore, I do not see any infractions of the tournaments T&C, and no disqualifications are required.
[Moderator Input] Personally, I do understand that you wish to discuss the T&Cs of this tournament. However, since you clearly specify in the opening post that this thread is targeted towards Relic whilst demanding a response from Relic staff, I am closing this thread. Threads should encourage discussion between fans rather than require participation from Relic or SEGA staff. I do encourage you to get an answer to your question, therefore I highly recommend to contact Relic or SEGA directly to discuss what you believe are legal issues of this tournament. I do strongly believe that you will get better results than discussing legal issues in a fan oriented discussion forum.
HTH"
While I think the Mod there gave an accurate reply, I don't think the T&C are particularly brilliant.
In essence, you have a Canadian Company (Relic) organising an international event with the assistance of the London office of its Japanese holding company (SEGA). The eligibility criteria for that event are provided by US legislation...and the law governing the agreement between the official organiser (SEGA) and the players is English law. WTF?
In the highly unlikely event that any litigation ensued from eligibility, it means the Claimant would have to apply to the English High Court,.who may require an expert on US law to give evidence concerning the treaty. And the witness(es) as to fact would have to be flown from Canada.
It would have made more sense for the Canadian rules of eligibility to be applied, and for the law of the agreement to be Canadian.
I don't know what the Canadian exclusions are (if any), but if they currently differ from US exclusions, it could be possible for a person to comply with the US exclusions, only to run foul of Canadian visa requirements. And then litigate in London?
I won't say an jntern drafted these rules, but you have to wonder.
