MIDWEST FLIGHT ATTENDANTS FOR FAIR AND EQUITABLE SENIORITY INTEGRATION v. INTERNATIONAL BROTHERHOOD OF TEAMSTERS AIRLINE DIVISION 135
The McCaskill–Bond Amendment to the Federal Aviation Act, 49 U.S.C. § 42112 note, provides that a transaction “for the combination of multiple air carriers into a single air carrier” requires the combined business to merge the seniority lists of the two carriers' employees.
Legislatures do not mean things in the abstract; as Justice Holmes once put it, the right question is what they meant by what they said. “[A statute] does not disclose one meaning conclusively according to the laws of language. Thereupon we ask, not what this man meant, but what those words would mean in the mouth of a normal speaker of English, using them in the circumstances in which they were used․ But the normal speaker of English is merely a special variety, a literary form, so to speak, of our old friend the prudent man. He is external to the particular writer, and a reference to him as a criterion is simply another instance of the externality of the law․ We do not inquire what the legislature meant; we ask only what the statute means.” Oliver Wendell Holmes, Jr., The Theory of Legal Interpretation, 12 Harv. L.Rev. 417, 417–19 (1899), reprinted in his Collected Legal Papers 204, 207 (1920). What the McCaskill–Bond Amendment means is not hard to discern.
The statutory requirement that the (formerly) separate carriers operate as a single carrier matters when the carriers maintain separate businesses. Although United Airlines and Continental Airlines have merged (rather, their holding companies have merged), they have continued to operate as separate businesses, integrating their operations only slowly. Until the joint operations have reached the point that they have become a “single air carrier,” they need not merge their seniority lists. Midwest, by contrast, integrated operations with Republic, Chautauqua, and Shuttle America expeditiously; that's why it was able to give up its certificate and planes, while transferring gates and landing slots for use by the other jointly operated carriers. Midwest and Republic engaged in a “covered transaction.” The later wasting away of Midwest illustrates the completeness of the integration; it does not negate the statute's coverage.
The judgment is reversed, and the case is remanded for proceedings consistent with this opinion.
