That is the exact wording, From The Ruling. It has not changed since this "rulegate" started. Molly's own words stated there is nothing "official" so if we just roll over, that wording stands, because that is what the FEI officially states. This is not something for lawyers, this is for friggin Presidents of all NF FEI regulated disciplines to present to their memberships, not for clarification, its pretty clear, but to decide if this type of rule is viable for the sport.
If an athlete, horse or an FEI official participates in a
non-sanctioned event, such person or horse will be prohibited from
participating in any sanctioned events, both international and national, for a
period of six months thereafter. An unsanctioned event is an event that is not
on the FEI calendar and is not authorised by a National Federation."
