the Eastern Ukraine where Russian citizens are being killed". In response, in January 2016 Kolomoyskyi filed a complaint against Russia at the Permanent Court of Arbitration. The Russians maintained that the intergovernmental court has no jurisdiction over the matter and refused to participate in proceedings. They responded with their own charges against Kolomoyskyi, accusing him, in his support for Ukrainian resistance to Russian-backed separatists in the Dontesk and Luhansk, of "organizing the killing of civilians". Russia asked for Kolomoyskyi to be put on Interpol's wanted list. On 2 July 2014, a Russian District Court called for his arrest. As governor, Kolomoyskyi went to some lengths to maintain a reputation for ruthlessness: visitors to his office were unsettled by an enormous shark tank. Once he became mayor of Dnipro in November 2015, and after his boss's ouster as governor, Filatov found Kolomoyksyi's "oligarch mentality" unchanged: "he started calling to ask me favours". Conflict with President Poroshenko On 25 March 2015, Ukrainian President Petro Poroshenko signed a decree dismissing Kolomoyskyi from the post of Dnipropetrovsk RSA Head, saying "Dnipropetrovsk region must remain a bastion of Ukraine in the East and protect peace". Kolomoyskyi was replaced by Valentyn Reznichenko. This followed a struggle with Poroshenko for control the state-owned oil pipeline operator. After Poroshenko's dismissal of Oleksandr Lazorko, who was a protégé of Kolomoyskyi, as a chief executive of UkrTransNafta, Kolomoyskyi dispatched his private security guards to seize control of the company's headquarters and expel the new government-appointed management. While Lazorko was in charge the state-owned pipelines had been delivering oil to an Kolomoyskyi-owned refinery in preference to competitors. In a further move against Kolomoyskyi, Poroshenko replaced Kolomoisky's long-time business partner Ihor Palytsa as governor of neighboring Odesa Oblast with the former Georgian president, Mikheil Saakashvili. That appointment triggered a dramatic and public war of words between Kolomoyskyi and Saakashvili. Saakashvili told journalists Kolomoyskyi was a “gangster” and “smuggler.” Kolomoyskyi told them Saakashvili was “a dog without a muzzle” and “a snotty-nosed addict.” Kolomoyskyi responded that the only difference between Poroshenko and Yanukovych is “a good education, good English and lack of a criminal record.” Everything else is the same: “It’s the same blood, the same flesh reincarnated. If Yanukovych was a lumpen dictator, Poroshenko is the educated usurper, slave to his absolute power, craven to absolute power.” Dnipro Guard The Russian invasion of Ukraine in February 2022 again highlighted the presence in
