Australian company Alumina has filed a counterclaim against US group Alcoa, which last month turned to a Delaware court to prevent its partner in Alcoa Worldwide Alumina and Chemicals (AWAC) from blocking a demerger plan.
Alumina said on Monday that its counterclaim sought court declarations to prevent Alcoa from taking further steps in its separation plan, announced in September, without complying with certain obligations under the AWAC agreements.
