LMRA Section 303 Does Not Completely Preempt State Property-based Tort Claims: Ninth Circuit | Practical Law
In Retail Property Trust v. United Brotherhood of Carpenters & Joiners of America, the US Court of Appeals for the Ninth Circuit held that Section 303 of the Labor Management Relations Act (LMRA), which prohibits unions from engaging in secondary picketing or boycott activities, does not completely preempt all state law property-based tort claims such as trespass and public nuisance related to union conduct that also might be that kind of secondary activity. The decision creates a split between the Ninth Circuit and the US Court of Appeals for the Seventh Circuit, which held that Section 303 has a sufficient preemptive power to convert ordinary state law complaints into federal claims and supplant the state law causes of action.
