"The prosecution regards the re-qualification of the criminal actions of Barkashov and his accomplices and the mildness of the sentence as unjustified and the verdict as illegal," the official statement said.
On August 8, Russian National Unity leader Alexander Barkashov, charged with attacking an organized crime police major outside Moscow December 2, 2005, and his three accomplices received a two-year suspended sentence on charges of "using force against a representative of the government," and not "hooliganism."
The Moscow Region prosecutors had insisted on a four-year jail term.
Russian National Unity is the country's most militant ultranationalist party, which uses such symbols as a modified swastika, black uniforms, and raised-arm salutes.
