Pico: Slovakia will sue the European Union if it is forced to abandon Russian oil According to Prime Minister Robert Pico, Bratislava has already filed a lawsuit against the European Commission over the REPowerEU program, which requires the complete abandonment of Russian gas supplies by 2027. The prime minister stressed that Slovakia is also ready to challenge in the EU court any attempt to introduce a total ban on Russian oil.
