Scoring: IMP
North-South are playing a strong club system and have the following auction up to the point when the director is called:
1♣(1):pass:2♠(2):3♥
4♠(3)
(1): 15+ any.
(2): Both minors 6-10hcp at least 5+/5+ but alerted late and simultanteously to an attempt to withdraw the 4♠ bid.
(3): Later described by both North and South as unequivocally to play (i.e. South would certainly have passed it).
A few other important facts:
North was using a left-handed bidding box which he had sitting on the North-West corner of the table and he uses his left hand to extract bidding cards which he places quite close (around 5cm or 2 inches) from his bidding box as he makes his bids.
The 4♠ bid was held about 1cm or 2cm (less than an inch) above the exisitng 1♣ bid in a position where West could see the face of the bidding cards, but neither East nor South could see anything other than a reasonably thick wad of bidding cards. When questioned by the director, West expressed uncertainty about whether he saw 3♠ or 4♠ due to the way that North was holding the bidding cards.
North freely admitted that when he pulled the 4♠ bid out of the box he intended to bid 4♠ but then suddenly remembered the correct conventional meaning of 2♠ and belatedly alerted and put his bidding cards back in his box.
The director was called at this point and ascertained that South had not seen what North had bid and after a few minutes of deliberation and consulation with other directors returned to the table with a copy of the recently amended Australian bidding box regulations in use for the very first time in this event:

C. BIDDING BOXES
3.5 A call is considered made (without screens) when a bidding card is removed from the bidding box and held touching or nearly touching the table or maintained in such a position to indicate that the call has been made.
3.6 A call selected may be changed without penalty if it is determined by the Director that
• It is a call selected unintentionally or
• It has not passed the screen and the Director consents to the change.

The Director first allowed West the option of changing his 3♥ call due to the late alert (which West declined to do) and then allowed North to substitute the 4♠ bid with his desired call (after which North-South motored into a cold 6♣ contract).
Adding insult to injury, the director was kind enough to inform East-West that had the previous regulations still been in place (which essentially deemed any call "made with intent" to be irrevokable) he would've ruled the other way with a result of 4♠-2.
East-West appealed arguing that 4♠ was a call that ought to have been "considered made" and was not able to be changed without penalty as the bid was made intentionally.
How do think the appeals committee should rule?
