702.10. Looking at Secret Information [Warning]: A player looks at information that is not available to any player. See CR 127 Privacy for information types.

702.10.a. Players should not be penalized via a remedy for errors their opponents make. Example: If one of your opponents inappropriately flips over the top card of their deck, you do not receive a penalty if you see it.
702.10.b. Remedies:
702.10.b.1. If possible, take involved cards in the now-known secret information and re-randomize them with the original randomized source of appropriate cards to remove the information advantage.
702.10.b.2. If this is not possible, reveal the information to all players to remove the information advantage and instruct the players to continue playing.
