Bid out of turn

[blackshoe]

I think Bad_Wolf should clarify whether he was a playing director, and whether if so he was also the dealer in this incident. This assumes, of course, that he was in fact the director, whether playing or not. Maybe he should clarify that too.

 

That said, the answer to the question in the OP ("What are dealer's legal obligations after he does not accept his RHO's LOOT?") is simple: make a legal call. He can psych or otherwise deviate from his agreements if he likes, so long as there is no partnership understanding about such calls. He can call according to his partnership understandings. He chose, apparently, to deviate from his agreements. That's legal. It's not "dodgy" or unethical. His side has no obligation (and indeed his partner cannot, because he doesn't know) to tell their opponent that he has deviated from partnership understanding. In fact, if asked, his side should describe the partnership agreement as to the meaning of his call, not what he has in his hand.
