I've found it :


Ton Kooijman:

Law 50E
The knowledge that a penalty card has to be played at the first legal 
opportunity is admissible information
for both sides and has a remarkable consequence. Declarer is playing 4♥. 
If LHO holds ♠KQJ5,
RHO has ♠A as a penalty card (first lead from the wrong side) and 
declarer does not forbid a spade
lead, LHO is allowed to play ♠5 - but he is not allowed to use the 
information that his partner seems to
have ♠Ax. If this results in an extra trick for the defending side, the 
TD should use his discretionary
powers, as described in Law 12A1, to adjust the score.
