The Czech power authority plans to file an appeal with the highest administrative court this week, challenging an injunction that prevents it from signing a nuclear power plant construction deal with Korea Hydro & Nuclear Power.

According to government sources on Sunday, Czech authorities explained during Industry Minister Ahn Duk-geun’s recent visit to Prague that the Czech utility company Elektrárna Dukovany II plans to appeal the injunction.

Elektrárna Dukovany II is a subsidiary of the country’s main electricity firm, CEZ, and is in charge of the nuclear power plant construction project.

A Czech regional court granted the injunction last week after French energy company EDF, one of the losing bidders, filed a legal challenge.

Under the Czech judicial system, the Supreme Administrative Court has the final ruling when a party appeals an injunction.
