Sayenko Kharenko was founded in 2004 and is one of the larger law firms in Kiev, boasting more than 100 lawyers and 14 partners. It has worked on arbitrations since 2008 but it became much more prominent after 2011 when Tatyana Slipachuk joined from another Ukrainian firm, Vasil Kisil & Partners.

A well-known arbitrator, Slipachuk helped to found the Ukrainian Arbitration Association (UAA) in 2012 and served as its president until 2016. She was also secretary general of the International Commercial Arbitration Court at the Ukrainian Chamber of Commerce and Industry for 10 years.

Between 2012 and 2016, Slipachuk shared leadership of the arbitration practice with the respected Olena Perepelynska (the current UAA president). Perepelynska, however, joined a rival Ukrainian firm, Integrites, in 2015. Slipachuk herself resigned from the partnership in October 2018 to take up a prestigious appointment as chair of Ukraine’s Central Electoral Commission.

The practice is now led by Olexander Droug, who was made partner in 2018 and is also on the board of the UAA. The team also includes counsel Volodymyr Yaremko. 

Recent events

Sayenko Kharenko is co-counsel with Latham & Watkins on the defence of Ukraine against a US$4.7 billion Energy Charter Treaty claim before the SCC. The claim, which is the largest the state currently faces, is from companies owned by Ukrainian billionaire Igor Kolomoisky and concerns the country’s largest oil and gas producer, Ukrnafta.

The two law firms are also defending Ukraine against a US$700 million ICSID claim from the co-owner of what was once the country’s largest commercial airline.

Cypriot chemicals company Ostchem Holding recently used the firm to enforce a US$260 million SCC award against a state-owned producer of fertilisers. Ukraine’s Supreme Court refused to enforce the award in mid-2018.

The firm is also representing three Brazilian footballers who are trying to enforce a CAS award against bankrupt Ukrainian team FC Metalist.

Client comment

One client who is using Sayenko Kharenko in an ICC dispute says he is extremely “satisfied” with the firm’s work and “few firms” in Ukraine can match it. He describes Droug and Yaremko as helpful, professional and methodical.
