For more than a decade, epidemiological surveys have shown that Taranto, Italy, has a critical health situation. In particular, two epidemiological reports have established a causal link between mortality and morbidity in Taranto and the industrial production of Ilva, one of Europe’s largest steel mills. Despite its negative impact on local health, Ilva has been allowed to produce thanks to a favorable legal framework. In particular, this article focuses on seven years central to the recent history of Ilva (2011–2017), in which the state has engaged in frenetic and compulsive lawmaking aimed to establish a favorable legal environment for Ilva to continue producing. It shows how the law has become an avenue for the Italian state and Ilva to establish a symbiotic relationship that has created the conditions to produce and reproduce harmful corporate practices. These laws are presented in juxtaposition with academic research and epidemiological surveys on Taranto’s public health, thus showing how the Italian state has responded to the increasing amount of evidence of corporate harm done in Taranto. The article contributes to the criminological scholarship on state-corporate crime and social harm by discussing the role of state law in the production and reproduction of harmful corporate practice. It also advances the literature on the Ilva case with a novel socio-legal reading of the socioenvironmental conflict ongoing in Taranto.
