Simultaneous Call for a Discard with Both for Mah Jongg (Article ID 92)
Abstract: When two players simultaneously call the same tile for mah jongg, the player next in turn gets the tile. However, if two players call the same tile for mah jongg and one player has started to expose their tiles, they are entitled to the tile regardless of whether they are next to pick.
Question from a player: I called mah jongg on a discarded tile. Just a few seconds later, the player next in turn to the discarder also called mah jongg on the same discarded tile. Who is entitled to the mah jongg?
Answer from the NMJL: “If two players simultaneously call a tile for mah jongg, the player next in turn is entitled to the claim, except when the other mah jongg declarer has begun to expose their tiles.”

Other answers from the NMJL:
“Just as long as you have not exposed your hand, the player next in turn would have priority.”
“If two people call a tile for mah jongg simultaneously, the person nearest in turn to the discarder gets the preference.”
“Just as long as Player #3 had not started to make any exposure as yet, next in turn (Player #2)would be entitled to the mah jongg.”
