Litigation expert Andrew Barns-Graham of Pinsent Masons, the law firm behind Out-Law, said Tatiana Akhmedova's enforcement strategy in the case had been "exactly right".
"Plainly there is no prospect of Mr Akhmedov complying with the court orders, so instead she has targeted the individual professionals who administer his asset holding vehicle, and who will not wish to be the subject of criminal contempt proceedings," he said.
"As well as being an example of an effective enforcement strategy, this case also contains helpful summaries of the law regarding what constitutes a 'de facto' director and the circumstances in which de facto directors should be named in a penal notice," he said.
Farkhad Akhmedov was ordered to pay £453,576,152 worth of financial support to Tatiana Akhmedova in December 2016. To date, Mr Akhmedov has only paid a "very small proportion" of the award to his ex-wife. In March 2018, the High Court made a freezing order against Straight, the registered owner of Farkhad Akhmedov's €250 million yacht, for the outstanding amount.
In the latest court proceedings, Tatiana Akhmedova sought extended injunctive relief against Straight, preventing "any voyage or movement" of the yacht, particularly its removal from port in Dubai. She also sought to name its de facto directors, who are Liechtenstein-based lawyers, in the accompanying penal notice.
Mrs Justice Knowles ruled that it was "just and convenient" to grant the orders sought, "even though Straight and Mr Akhmedov have a history of breaching this court's orders".
"The order will be enforceable here against Straight, an entity which has previously been found to have submitted to the jurisdiction," she said. "Additionally, these orders should provide a serious incentive to [its directors] to ensure Counselor [Straight's corporate director] and Straight act in compliance with what is required of them."
The judge said that there were no rules of the court requiring a penal notice to identify every individual against whom contempt of court proceedings could be brought. However, in this case, she thought it was worth listing Counselor's directors by name in the notice in order to put them "on proper notice of the possible consequences of failure to comply if they cause (or continue to cause) Straight to act in breach of this court's order".
