Alright so I came across this problem while someone was playing. So it was 3rd game and the score was 23-22. The person serves and the rally went on normally until that person won the point bring the game to 24-22 (won). But apparently both players didn't notice that they were standing on the wrong side in the beginning of the serve until later. So I was wondering what the official international badminton rule would have to say about this. who gets the point and etc.?
