LAW 21 | _CALL BASED ON MISINFORMATION_
A. | Call Based on Caller’s Misunderstanding
| A player has no recourse if he has made a call on the basis of his own misunderstanding.
B. | Call Based on Misinformation from an Opponent
| 1. | Change of Call
|  | Until the end of the auction period (see Law 17E), a player may, without penalty, change a call when it is probable that he made the call as a result of misinformation given to him by an opponent (failure to alert promptly to a conventional call or special understanding, where such alert is required by the sponsoring organisation, is deemed misinformation), provided that his partner has not subsequently called.
| 2. | Change of Call by Opponent Following Correction
|  | When a player elects to change a call because of misinformation (as in 1., preceding), his LHO may then in turn change any subsequent call he may have made, without penalty (unless his withdrawn call conveyed such information as to damage the non-offending side, in which case the Director may assign an adjusted score). (For unauthorised information from withdrawn calls, see Law 16C.)
| 3. | Too Late to Change Call
|  | When it is too late to change a call, the Director may award an adjusted score (Law 40C may apply).
