Legalities
On 2 May 2007, a criminal investigation was opened into the attacks under a section of the Estonian Penal Code criminalising computer sabotage and interference with the working of a computer network, felonies punishable by imprisonment of up to three years. As a number of attackers turned out to be within the jurisdiction of the Russian Federation, on 10 May 2007, Estonian Public Prosecutor's Office made a formal investigation assistance request to the Russian Federation's Supreme Procurature under a Mutual Legal Assistance Treaty (MLAT) existing between Estonia and Russia. A Russian State Duma delegation visiting Estonia in early May in regards the situation surrounding the Bronze Soldier of Tallinn had promised that Russia would aid such investigation in every way available. On 28 June, Russian Supreme Procurature refused assistance, claiming that the proposed investigative processes are not covered by the applicable MLAT. Piret Seeman, the Estonian Public Prosecutor's Office's PR officer, criticized this decision, pointing out that all the requested processes are actually enumerated in the MLAT.
On 24 January 2008, Dmitri Galushkevich, a student living in Tallinn, was found guilty of participating in the attacks. He was fined 17,500 kroons (approximately US$1,640) for attacking the website of the Estonian Reform Party.
As of 13 December 2008, Russian authorities have been consistently denying Estonian law enforcement any investigative cooperation, thus effectively eliminating chances that those of the perpetrators that fall within Russian jurisdiction will be brought to trial.
