Deputy Finance Minister Yurii Butsa told Reuters via CNBC, Censor.NET reports.
The official does not see how the case will affect the IMF program, since the fund will decide April 3 on granting Ukraine the fourth loan tranche worth $1 billion.
Details of the requirements to be fulfilled by Kyiv in order to secure the fifth tranche are expected to be published next week, said Butsa.
"The next one (memorandum) will be in the same direction as the existing one - so we will be moving in the same direction and trajectory," he said on the sidelines of investor meetings in London.
"But obviously there is one big issue which is the pension reform, on which we are already working a lot," the deputy minister added.
Butsa said the government was working on a draft of the pension reform and expected to start discussing the proposals with all parties concerned in the weeks to come.
On March 29, the High Court of Justice ordered Ukraine to pay off the $3 billion debt and accrued interest. The court also allowed Ukraine to file an appeal and suspended its decision on the repayment of debt to Russia.
