Roger Eymard :

Questions and answers seem to have happened after the final pass. So L20F2 
applies, and does not contain any requirement as to who explains what are NS 
agreements. L75D2 does apply, and if there is a proof that the meanings of 
4NT and 5D have been given in accordance with the actual agreement, I don't 
see any duty for South to correct North's explanations, nor any basis for a 
score adjustment.
OTOH, if *by agreement*, 4NT does not *show* a H control, so that 5D does 
not *show* a D control, (nor deny a C control - did 4H promise or deny any 
other control ?), South must correct North's explanation, so that the leader 
know that neither D control nor C control have been shown in the bidding. 
L12 applies... 100 for EO and a warning to NS for not calling the TD and for 
a breach of Chapter VII requirements.
