The Supreme Court of Russia (Russian: Верховный Суд Российской Федерации) declared the DPNI an extremist organisation and banned it in 2011.

Aside from mass protests the movement is active in organizing public pressure to support ethnic Russians in number of high-profile court cases involving crimes committed by the immigrants.

[6] During ethnic riots in the northern Russian city of Kondopoga, in August–September 2006, the DPNI provided an up to the minute online coverage of the unfolding situation in response to what it saw as the media's politically correct silence about what was happening there.

[7] DPNI representatives arrived in the town shortly after riots had commenced, and were able to largely control the flow of news and events in the absence of any reaction from local authorities or police.

[10] On 26 June 2007, the DPNI announced the formation of armed "People's Self-Defense" groups to defend "indigenous citizens" against "the aggressive actions of criminal migrants."

"[11] In April 2005, the DPNI had announced creation of "mobile fighting groups", composed of cell networks of five persons each, whose members would have access to automobiles and legal weapons.

The 2005 announcement cited a "possible worsening of the internal political situation in the Russian Federation and the likelihood of mass disorders and aggressive actions by foreign states.

"[12][13] By the verdict of the Dorogomilovsky District Court of Moscow dated 28 May 2009, the leader and head of the DPNI Alexander Potkin (Belov) was found guilty of committing a crime under Part 1 of Art.

The court found that, on Moscow DPNI leader's instructions, persons unidentified by the investigation attacked citizens of the Republics of Tajikistan, Uzbekistan, Vietnam, causing bodily harm.
