| Arbitral immunity has its origins in common law judicial |
| immunity; most jurisdictions track the common law directly. |
| The key to this identity is the "functional comparability" of |
| the role of arbitrators and judges. See Butz v. Economou, 438 |
| U.S. 478, 511-12 (1978) (establishing the principle that the |
| extension of judicial-like immunity to non-judicial officials |
| is properly based on the "functional comparability" of the |
| individual's acts and judgments to the acts and judgments of |
| judges); see also Corey v. New York Stock Exch., 691 F.2d |
| 1205, 1209 (6th Cir. 1982) (applying the "functional |
| comparability" standard for immunity); Antoine v. Byers & |
| Anderson, Inc., 508 U.S. 429, 435-36 (1993) (holding that the |
| key to the extension of judicial immunity to non-judicial |
| officials is the "performance of the function of resolving |
| disputes between parties or of authoritatively adjudicating |
| private rights"). |
