Are state law claims against employers preempted by federal labor law? Peterson v. Delta Air Lines Explained

In Peterson v. Delta Air Lines, the Utah Court of Appeals addressed when the Railway Labor Act (RLA) preempts state law claims against employers in the airline industry. The case provides important guidance on the boundaries between federal labor law and state tort claims.

Background and Facts

Robert Peterson, a thirty-year veteran pilot, was scheduled to retire at age 60 as required by FAA regulations. He had planned a ceremonial “final flight” on December 31, 1996. However, when Delta placed Peterson on short call status during Christmas, he called in sick, telling the crew scheduler he wasn’t feeling well during his last month. Delta’s Chief Pilot initiated an investigation for abuse of the sick leave policy under the collective bargaining agreement (CBA), suspending Peterson and causing him to miss his final flight. Although Peterson was later reinstated after providing medical certification, FAA regulations prevented him from rescheduling his final flight.

Key Legal Issues

The central issue was whether Peterson’s state law claims for breach of implied contract, civil conspiracy, and intentional infliction of emotional distress were preempted by the RLA. The court applied the test from Hawaiian Air Lines v. Norris: the RLA preempts state claims when resolution requires interpreting the CBA.

Court’s Analysis and Holding

The court found all three claims required CBA interpretation. For the implied contract claim, any custom regarding final flights had to be analyzed against the CBA’s comprehensive coverage of “all flying performed by or for” Delta. The conspiracy claim required determining whether Delta’s investigation and suspension were unlawful, which depended on Delta’s authority under the CBA. Even the emotional distress claim was preempted because Peterson’s complaint centered on Delta’s withholding of flight privileges—a matter of managerial authority governed by the CBA.

Practice Implications

This decision illustrates the broad scope of RLA preemption in airline employment disputes. Practitioners must carefully craft state law claims to avoid any dependence on CBA interpretation. The court emphasized that claims are only “independent” if they can be resolved without reference to the collective bargaining agreement. Even seemingly personal misconduct by supervisors may be preempted if it involves the exercise of authority defined by the CBA.
