There were no alerts. South had no possibility of describing the 6-5
as all 2-suited options were constructive. South asserted that she
would have bid 4S over 2D had she been aware that the opponents were
using "inverted minors".
Director rule score stands and NS appealed.
The AC agreed that this particular South may have bid 4S but
determined that it was not an action that would be given serious
consideration by a significant proportion of experienced players in
the field.
------------------------------------------

It seems to me that the AC is confusing MI with Logical Alternatives.
The fact or opinion that other players would not bid 4S would seem to
me to be irrelevant in determining whether this particular South was
damaged by a failure to alert the inverted minor raise.

To once the AC agree that South may have bid 4S then they must come to
the conclusion that the failure to alert has caused damage.

+=+ I would say the AC has indicated that it does not believe
South and has quoted wider probabilities of action by peer
players as the basis for ts judgement.
