Exxon Co. v. Sofec, Inc.
Headline: Court affirms that legal causation and the superseding-cause rule apply in admiralty, blocking recovery when a shipowner’s extraordinary negligence alone caused a grounding.
Holding: The Court held that admiralty law requires legal (proximate) causation and that a plaintiff whose extraordinary negligence is the sole proximate cause cannot recover from others whose faults were only causes in fact.
- Bars recovery when a shipowner’s later extraordinary negligence is the sole legal cause.
- Prevents manufacturers from liability if their fault was only a cause in fact.
- Allows courts to use superseding-cause analysis and bifurcate maritime trials.
Summary
Background
A tanker owned and operated by Exxon broke away from a mooring and trailed a damaged oil hose. After the hose partially detached, the ship’s captain maneuvered for hours. By 1830 the ship had reached a safe position, but the captain then failed to plot the ship’s position and later turned toward shore, causing the ship to run aground and be lost. Exxon sued the pipeline operator, equipment manufacturer, and others for the loss under warranty, product, and negligence claims.
Reasoning
The Court addressed whether admiralty law still requires legal or "proximate" causation and the related superseding-cause rule after the Court adopted comparative fault in Reliable Transfer. The Court held that proximate causation and the superseding-cause doctrine remain applicable in admiralty and can bar recovery when a plaintiff’s own later, extraordinary negligence is the sole proximate cause. The Court agreed with the lower courts that Captain Coyne’s failure to plot positions was extraordinary negligence that superseded earlier defects or breaches, and it affirmed the judgment denying Exxon recovery.
Real world impact
The decision means that in maritime accidents, parties whose mistakes were only causes in fact may not be liable if a later, unforeseeable careless act by the ship or crew becomes the sole legal cause of the loss. The ruling also confirms that contractual warranty claims can be cut off for lack of legal causation and that courts may bifurcate trials to decide proximate causation first.
