The opening lead was the ♠6; South went down one.
2♦ was explained by N to West's question as "any 4414 or 4405, 11-15 or 19+". 2NT asked for the shortage. 3♥ was explained by North to East's question as "spade shortage". West was the playing director. North is also a club level director.
After East questioned 3♥, West said to East "I told you you're not allowed to ask questions in the bidding". North says "seems to me you asked a question". West replied "I have to protect my partner". North then said "that's illegal — it's against the rules". West said "I will always protect my partner". South then commented "Oh! do you have a different set of rules to the rest of us?" The auction and play then proceeded with no further discussion. No rulings were requested or made at the table. Both West and North are experienced club level directors (about 35 and 40 years, respectively) and are decent to excellent players. Their partners are perhaps club average (South) and somewhat less than that (East). West has a reputation for um, "inventive" rulings, and for rarely, if ever, changing his mind once he's decided to do something, come what may.
North, as stated, felt that West's "restriction" on East is against the rules. West, apparently, felt otherwise. There were no other problems. Comments?
