In the long-running and excellent discussion about the legal merits of the Landis Federal Filing, we have a recent comment by DR pointing to what he thinks is Landis' best claim:
In my view his strongest argument is based upon the failure of the arbitrator he chose to disclose potential conflicts.
See if you can wade through this:
Or if that puts you to sleep, just jump to the last couple of paragraphs.
Those last few paragraphs say,
 Under these circumstances, Immerman had a duty when he accepted the new job at Yari Film Group to investigate the possible conflicts that might arise from his new employment. However, even though Immerman breached his duty to investigate, vacatur is only appropriate if the conflict left undis-closed was real, see Schmitz, 20 F.3d at 1049, and “not trivial.” ANR Coal Co., Inc., 173 F.3d at 499 n.4. Understandably, courts have rejected claims of evident partiality based on long past, attenuated, or insubstantial connections between a party and an arbitrator. See, e.g., Positive Software Solutions, Inc. v. New Century Mortgage Corp., 476 F.3d 278, 284 (5th Cir. 2007) (en banc) (collecting cases). As Justice White explained in his concurrence in Commonwealth Coatings, it would be unrealistic to expect an arbitrator to “provide the parties with his complete and unexpurgated business biography.” Commonwealth Coatings, 393 U.S. at 151 (White, J., concurring).
 The conflict alleged by Nippon Herald is real and nontrivial. “The Night Watchman” negotiation was not distant in time, but rather ongoing during the arbitration. Nor was the connection between Yari Film Group and New Regency attenuated. Even if Milchan was not directly representing New Regency in the negotiations, she had substantial ties to the company as an executive of the company and the daughter of its principal owner and chief executive officer. Although the record does not allow us to place a dollar value on “The Night Watchman,” taking into account the high-profile nature of the film project itself, and the size of Yari Film Group’s business, we cannot conclude that the negotiation was unimportant to Yari Film Group.
 Under these circumstances, we hold that Immerman had a duty, when he accepted the new job at Yari Film Group during the arbitration, to investigate the possible conflicts that might arise from his new employment. We hold further, in light of that duty, that Immerman’s failure to disclose facts that show a reasonable impression of partiality is sufficient to support vacatur, notwithstanding the lack of evidence of his actual knowledge of those facts.
While we are cognizant of the public interest in efficient and final arbitration, we believe that a rule encouraging “arbitrators [to] err on the side of disclosure” is consistent with that interest. Id. at 152. As Justice White explained in Commonwealth Coatings, the “arbitration process functions best” where early and full arbitrator disclosure fosters “an amicable and trusting atmosphere” conducive to “voluntary compliance with the decree.” Id. at 151.Conclusion
For the foregoing reasons, we hold that the district court did not err in vacating the arbitration award on the ground of evident partiality.
