Hannes Snellman acted as counsel to NYAB Finland Oy in court proceedings to contest the termination of two construction contracts, relating to construction of a water treatment facility, where NYAB Finland Oy was the contractor and the City of Mikkeli was the employer. Mikkeli terminated the contracts mid-construction in March 2020. In December 2022, the Etelä-Savo District Court ruled that Mikkeli had no grounds for termination and awarded NYAB Finland Oy EUR 8.8 million (out of a claimed EUR 9.3 million) in damages, unpaid work, and costs, plus interest. Following the District Court ruling, the parties agreed on a settlement, whereby Mikkeli does not appeal and pays NYAB Finland Oy the sums awarded by the District Court plus interest up to a total of EUR 9.2 million.
