Moscow mayor's office said on Tuesday evening that it did not apprive the opposition rally planned for September 15. Rally organizers planned a rally and expected 50 thousand protesters. The initial application for the rally requested a route from centrally located Tverskaya street along to Mokhovaya street with the march's final destination at the Borovitskaya square, near the Kremlin.

The authorities explained the motivation behind the denial by saying that one of the organizers, Sergey Davidis, has allegedly been charged with two administrative offences, writes another opposition activist Sergey Udaltsov in his Twitter feed.

The ability to deny approval for mass rallies became possible only after the new anti-rally law was adopted. According to the law, a rally organiser cannot not have two or more offences on Article 20.2 of Russia's administrative code – "Violation of order during a rally."

Davidis, in an interview to Gazeta.ru, said that he knew about the new law and that had he checked into how many administrative offences he had received during the past year. Davidis was detained many times, but only two cases were brought to the court, and a verdict was returned in only one of them. "It does not matter how many times I was detained. It is important how many court verdicts I had, and I had just one," Davidis said.

Davidis' second case was stuck in the police department and never made it to court.

On Wednesday, opposition activists said that they have submitted a new application for a "March of millions."

"We submitted an application for the same route: from the Belorusskiy Railway Station along Tverskaya street and to Borovitskaya square. However, we changed the applicant – it is Denis Bilunov instead of Sergey Davidis," Sergey Udaltsov said.
