Nigeria's Supreme Court said a Shell Plc subsidiary can appeal a judgment directing the company to pay compensation over alleged pollution in a legal dispute that is holding up the oil giant's efforts to sell assets in the West African country.

On Friday, the highest court in Africa's largest economy allowed an application made by Shell's local unit and its joint venture partner, the state-owned Nigerian National Petroleum Co. They are challenging a November 2020 ruling by a federal court ordering the Shell subsidiary to pay 800 billion naira ($1.8 billion) to residents of the crude-rich Niger Delta over an alleged oil spill.

"We believe in the merits of our case and are encouraged that the Nigerian Supreme Court is hearing this matter," a spokeswoman for the Shell subsidiary said by email. "We look forward to the hearing of our main appeal."

An appeals court ruled in March that Shell cannot sell onshore and shallow water oil blocks it is trying to offload until its appeal against the compensation order is determined. The London-based oil major announced it was pausing the divestment process in June pending the outcome of the Supreme Court case.
