WARSAW, July 4 - RAPSI. Relatives of the Polish prisoners of war executed in the vicinity of Katyn in 1940 have challenged the European Court of Human Rights' April judgment in its Grand Chamber, counsel Dr. Ireneusz Kaminski told RIA Novosti.

"The wording of the complaint was finalized yesterday and it has been submitted to the court," the lawyer said on Wednesday.

Kaminski hopes that the hearing will be scheduled for September or October after the end of the holiday season.

On April 16, the Strasbourg Court announced its judgment over the appeal filed by the executed prisoners' relatives. The court found Russia guilty of violating Article 3 of the European Convention on Human Rights prohibiting torture, stating that the government did not provide the applicants with sufficient information regarding the fate of their relatives.

However, the court was unable to take agree with the complaint with regard to Article 2, concerning the right to life.

Kaminsky said that although the court recognized the government's violations under Article 3, the judges' opinions were split on Article 2, the more important aspect of the complaint for the applicants.
