General Prosecutor Jaromír Čižnár filed the motion with the Supreme Court, the news TV channel TA3 reported.
The information was officially confirmed for the Sme daily by the spokesman of the Supreme Court, Boris Urbančík.
The move of GP Čižnár to dissolve the party has been expected since the last election, with the General Prosecutor’s Office receiving about 170 notions. However, the office said for several months that it was awaiting expert information that would show whether the party's conduct and statements might constitute violations of Slovak law.
The first party of Kotleba, Slovenská Pospolitosť (The Slovak Togetherness), had faced similar complaints and was banned by the Supreme Court in 2006. The manifesto of Pospolitosť had proposed the abolition of the democratic system and the establishment of “a class state based on the national, Christian and social principle”.
It was the first decision on banning a party since the 1989 revolution that toppled the communist regime.
