What's the rule for a shuttle falling across into your court? I am at the Asian Junior U17/U15 Championships and I saw a couple of times shuttles from the next court flying across into the court area during play. The umpire totally ignored it and carried on play.
I don't know the official rule, but where I play you either carry on playing (and the people who are on the other court be best not to interrupt the point). Or; The players on the court stop playing the point as there is a hazard on the court that they could trip over. so play a "let" in that instance.
ITTO 5.9.1.2. A shuttle coming onto the court from an adjacent court shall not automatically be considered a “let”. A “let” shall not be called in such circumstances if, in the opinion of the Umpire, the shuttle has not obstructed or distracted the players;
