U.S.-based private equity firm Lone Star is considering legal action after a World Bank tribunal overturned an earlier arbitral award in its favor in a long-running investor-state dispute.

Lone Star said in a statement on Wednesday that it looks forward to presenting its case to a new tribunal.

The firm expressed confidence that the panel will again find that South Korea acted unlawfully in its handling of the planned sale of Korea Exchange Bank(KEB) and will award the full amount of claimed damages.

Lone Star voiced disappointment in the International Center for Settlement of Investment Disputes(ICSID), which on Tuesday overturned a 2022 order that South Korea to pay the firm 216-point-five million U.S. dollars plus interest.

The firm argued that the annulment, based on procedural grounds, does not change what it described as the underlying fact that South Korean regulators improperly blocked and interfered with its multiyear effort to sell its controlling stake in KEB.

Lone Star originally filed an investor-state arbitration claim in the ICSID in 2012, seeking four-point-68 billion U.S. dollars in damages.
