CHAPTER VI
The Play 

PART IV
TRICKS

LAW 66 - INSPECTION OF TRICKS 

A. Current Trick

So long as his side has not led or played to the next trick, declarer or either defender may, until he has turned his own card face down on the table, require that all cards just played to the trick be faced for his inspection.

B. Own Last Card

Until a card is led to the next trick, declarer or either defender may inspect, but not expose, his own last card played.

C. Quitted Tricks

Thereafter, until play ceases, quitted tricks may not be inspected (except at the Director's specific instruction; for example, to verify a claim of a revoke).

D. After the Conclusion of Play

After play ceases, the played and unplayed cards may be inspected to settle a claim of a revoke, or of the number of tricks won or lost; but no player should handle cards other than his own. If, after such a claim has been made, a player mixes his cards in such a manner that the Director can no longer ascertain the facts, the Director shall rule in favour of the other side.
