Arla has previously requested ÖMF Invest, the company behind Glada bonden i kvarstad.
But it was rejected in both the district court and the Göta Court of Appeal.
But now Arla is suing both AMF Invest and Boxholm municipality, something that P4 Östergötland was the first to pay attention to.
The company considers itself entitled to several cisterns, spare parts in a blue cabinet, filters and tanks.
SVT Nyheter Öst is looking for the municipalities of Arla and Boxholm.
