Allianz SpA v West Tankers is a preliminary ruling by the Grand Chamber of the Court of Justice of the European Union (CJEU) following a reference from the United Kingdom's House of Lords. The case stemmed from a 2000 incident in Syracuse (Italy), where the Front Comor, a vessel owned by West Tankers and chartered by Erg Petroli SpA (Erg), collided with a jetty also owned by Erg, causing damage to the jetty.
