Law 50 states:

Quote

A card prematurely exposed (but not led, see Law 57) by a defender is a penalty card unless the Director designates otherwise (see Law 49 and Law 23 may apply).

Suppose that the Director designates otherwise, i.e. says that the defender's exposed card is not a penalty card.

For that defender's partner, is the knowledge of his partner holding that card:

(i) unauthorised information, so he is constrained by Laws 16A and Law 73C;
(ii) authorised information, so he can defend knowing that his partner holds this card; or
(iii) neither, he should defend normally, as if he had not seen the exposed card?

I would use the following route to the answer:

1) I would call the card which was exposed but deemed by the TD to be neither a played card nor a penalty card ---under whatever Law---to be a "withdrawn" card subject to 16D.

2) Then, I would determine if the exposed card was possessed by the OS or by the NOS at the moment it was exposed, and apply 16D accordingly.

I think Agua's got the right approach, though I started with Law 16A1, which defines what information is authorized.
