In those cas- es, the court merely reviewed the arbitral award and held that the arbitrator could not fashion “other relief” if the LCA provided that, in case of a discharge for a drug offense, there will be 13 Further, Exxon does not point to any evidence that Salinas was even “medically evaluated” before her discharge in early 2003. Jones only declared that “by early 2003, when this dispute arose, Elizabeth Salinas . . . had been determined to be ‘incapaci- tated’ pursuant to the plan.” Jones does not explain whether the determination that Salinas was incapacitated for the purposes of performing a job in the Clerical Unit was based on a medical evalua- tion. Nor does Exxon indicate that there was a “review” of Salinas’s restrictions in 2003 and that because of her medical restrictions, she was deemed unable to perform any job for which she was quali- fied in the Clerical Unit. Although Exxon pointed out at oral argument that the union’s representative was instructed at a deposition not to answer the question whether Salinas was medically evaluated before her dis- charge in early 2003, the union does not bear the burden to prove Exxon’s defense to arbitrability. Exxon has access to information regarding Salinas’s medical evaluation and the review of her restrictions (because it performed the review itself if there was such a review). Therefore, Exxon cannot say that this evidence is not available on account of someone else’s failure to bring it forth. 11
