Ukraine's Supreme Court has closed all the criminal proceedings against former lawmaker from the Party of Regions, businessman Yuriy Ivaniuschenko, Prosecutor General of Ukraine Yuriy Lutsenko has said.

"Today we've learnt that the Supreme Court without notifying the prosecutor's office has decided to close all the proceedings against Ivaniuschenko," Lutsenko wrote on his Facebook page on Tuesday night.

The prosecutor general noted that this was done "just prior to the renewal of the EU sanctions against the arrested assets of [ex-president Viktor] Yanukovych and his allies."

"I have a lot of emotions [about this ruling] and many arguments against it. But this is the only way to change the composition of the Supreme Court of Ukraine as fast as possible," Lutsenko said.

As earlier reported, the Prosecutor General's Office of Ukraine (PGO) is investigating Invaniuschenko's alleged participation in a case involving the misuse of funds and illegal enrichment in large scale, pursuant to Part 3 of Article 27 (types of accomplices), Part 5 of Article 191 (embezzlement using official position), Part 3 of Article 368 (accepting a proposal, promise or receiving exorbitant remuneration while an official) of the Criminal Code of Ukraine.

Ukraine's Interior Ministry in January 2015 put Ivaniuschenko on the wanted list. It planed him in May 2015 on Interpol's international wanted list.

On April 1, 2016 Kyiv's Dniprovsky District Court revoked a search warrant for Ivaniuschenko, as well as sanctions for his arrest and delivery to a court for determination of pretrial confinement. The PGO later said it would appeal the ruling.

Avakov on April 2 said Interior Ministry would continue looking for Ivaniuschenko and would not obey the disgraceful ruling of the court.
