MOSCOW (Sputnik) — According to the ruling, Sviridov's entry and residence in Poland "violates interests" of the country.
"My office in Warsaw has received an official ruling of Poland's Office for Foreigners, according to which Leonid Sviridov is on the list of persons banned from entering Poland and Schengen zone states until December 14, 2020," Jaroslaw Chelstowski said.
The lawyer said that legal steps were due to be taken following a discussion with Sviridov on the issue.
In mid-December, 2015, Sviridov left Warsaw for Moscow to begin legal proceedings against the Polish authorities after Poland had made a final decision to annul his residence permit over unspecified allegations.
Sviridov's case has been included in the Organization for Security and Co-operation in Europe (OSCE) monitoring reports on freedom of the media, which documents violations of journalists' rights within OSCE member states.
