Slovakia won the arbitration lawsuit filed by Dutch-owned Achmea insurance company - the stakeholder of the Union health insurer - over Slovakia's plans to create a single health insurance company.

Achmea is now obliged to pay more than 1 million euros (1. 37 million U.S. dollars) to Slovakia to cover legal fees, informed the Finance Ministry press department on Thursday.

"The arbitration tribunal stated that the conception and implementation of the public health insurance system is fully under the remit of the state. Furthemore, the tribunal also stated that it doesn't have the power to interfere with democratic processes of a sovereign state and has no power to make a ruling on the dispute," said the ministry.

This wasn't the first legal battle for Slovak government concerning health insurance.

In March 2013, Slovakia secured a partial win in the arbitration in which former stockholder of the health insurer Apollo, Austrian company Euram Bank, is suing Slovakia over the ban on profits of health insurance companies and seeks 131 million euros in compensation. (1 euro = 1.379 US dollar)
