The district court properly sent plaintiff’s other claims to arbitration and then, based on the arbitrator’s factual findings, dismissed the Sarbanes-Oxley Act retaliation claim which it had not sent to arbitration. The SOX Act prevents SOX claims from being subject to mandatory pre-dispute arbitration agreements. 18 U.S.C. § 1514A(e). Although an arbitrator’s decision can never preclude a SOX claim, a confirmed arbitral award can sometimes preclude re-litigation of the issues underlying a SOX claim. A confirmed arbitration award resolving an arbitrable claim may have collateral estoppel effect precluding a separate claim made non-arbitrable by statute. Here, the arbitrator found that plaintiff lacked a reasonable belief that his complaint to the SEC reported any violation of federal securities laws. That finding precluded plaintiff’s non-arbitrable SOX retaliation claim as well as his arbitrable Dodd-Frank Act anti-retaliation claim.
