LAW 25 | _LEGAL AND ILLEGAL CHANGES OF CALL_
A. | Immediate Correction of Inadvertency
| Until his partner makes a call, a player may substitute his intended call for an inadvertent call but only if he does so, or attempts to do so, without pause for thought. If legal, his last call stands without penalty; if illegal, it is subject to the applicable Law.
B. | Delayed or Purposeful Correction
| Until LHO calls, a call may be substituted when Section A does not apply:
| 1. | Substitute Call Condoned
|  | The substituted call may be accepted (treated as legal) at the option of offender’s LHO (6); then, the second call stands and the auction proceeds without penalty. If offender’s LHO has called before attention is drawn to the infraction and the Director determines that LHO intended his call to apply over the offender’s original call at that turn, offender’s substituted call stands without penalty, and LHO may withdraw his call without penalty (but see Law 16C2).
| 2. | Not Condoned
|  | If the substituted call is not accepted, it is cancelled, and
|  | (a) | First Call Illegal
|  |  | if the first call was illegal, the offender is subject to the applicable law (and the lead penalties of Law 26 may apply to the second call).
|  | (b) | First Call Legal
|  |  | if the first call was legal, the offender must either
|  |  | (1) | Let First Call Stand
|  |  |  | allow his first call to stand, in which case (penalty) his partner must pass when next it is his turn to call (see Law 23 when the pass damages the non-offending side), or,
|  |  | (2) | Substitute Another Call
|  |  |  | make any other legal call, in which case (penalty) the auction proceeds normally (but offender’s partner may not base calls on information from withdrawn calls); the offending side (7) may receive no score greater than average minus (see Law 12C1).
|  | (c) | Lead Penalties
|  |  | In either case (b) (1) or (b) (2) above, the offender’s partner will be subject to a lead penalty (see Law 26) if he becomes a defender.
(6) When the original bid was insufficient, apply Law 27 (7) The non-offending side receives the score achieved at the table
