| This exception is designed to preserve traditional contract | 
| defenses to the enforcement of the mediated settlement | 
| agreement that relate to the integrity of the mediation | 
| process, which otherwise would be unavailable if based on | 
| mediation communications. A recent Texas case provides an | 
| example. An action was brought to enforce a mediated | 
| settlement. The defendant raised the defense of duress and | 
| sought to introduce evidence that he had asked the mediator to | 
| permit him to leave because of chest pains and a history of | 
| heart trouble, and that the mediator had refused to let him | 
| leave the mediation session. See Randle v. Mid Gulf, Inc., No. | 
| 14-95-01292, 1996 WL 447954 (Tex App. 1996) (unpublished). The | 
| exception might also allow party testimony in a personal | 
| injury case that the driver denied having insurance, causing | 
| the plaintiff to rely and settle on that basis, where such a | 
| misstatement would be a basis for reforming or avoiding | 
| liability under the settlement. Under this exception the | 
| evidence will not be privileged if the weighing requirements | 
| are met. This exception differs from the exception for a | 
| record of an agreement in Section 6(a)(1) in that Section | 
| 6(a)(1) only exempts the admissibility of the record of the | 
| agreement itself, while the exception in Section 6(b)(2) is | 
| broader in that it would permit the admissibility of other | 
| mediation communications that are necessary to establish or | 
| refute a defense to the validity of a mediated settlement | 
| agreement. |
