Where do you see this rule that these pairing restrictions are only forbidden in norm events. My child has played in several CCA events in the FIDE section and has had to play against others from our state. So frustrating since we try to go out of state to avoid the people we already play against all the time.
CCA does not restrict pairings by state. For that matter, neither do most tournaments as it can easily create problems. CCA does, however, try to prevent pairings for players from the same household or upon request before the tournament.
