As reported by Censor.NET this was announced by Head of the Petro Poroshenko Bloc faction in the Verkhovna Rada Artur Herasymov during a meeting of the conciliatory council of the leaders of parliament's factions, committees and groups.
"We demand that the independent newly created anti-corruption authorities - the National Anti-Corruption Bureau, the Anti-Corruption Prosecutor's Office - launch an immediate and public check into the situation and inform the parliament about the results within two weeks," he said.
He also called on the Parliamentary Committee for National Security and Defense, as well as the Anti-Corruption Committee to call upon Yuliia Tymoshenko to attend their meetings and consider "the issue of high treason and the corruption component of the 2009 gas contract."
As reported, in 2009 Yuliia Tymoshenko signed a contract with Vladimir Putin on the supply of Russian gas to Ukraine. The contract contained the "take-or-pay" principle stipulating fines for Ukraine in the event it failed to take the amount of Russian gas specified in the contract.
This principle became the reason for Ukraine's Naftohaz to take action in the Stockholm Arbitration Institute in 2014. The company demanded that Gazprom cancel the "take-or-pay" principle and pay out a compensation in the amount of $30.3 billion for revising the tariff for transporting the fuel via the European gas transportation system.
On May 31, the Stockholm Arbitration Institute passed a judgment on the dispute between Naftohaz Ukrainy and Gazprom regarding the 2009 gas contract.
The court ordered to:
1) abolish the "take-or-pay" principle;
2) cancel the prohibition to re-export gas;
3) revise the 2014 price formula (a European price was introduced).
