Dangote Petroleum Refinery and Petrochemicals FZE has filed a lawsuit with the Federal High Court in Abuja, seeking to annul the import licenses granted to the Nigerian National Petroleum Corporation (NNPC), Matrix Petroleum Services, A. A. Rano, and four other oil companies. According to Nairametrics, these licenses permit the companies to import refined petroleum products, but Dangote contends that it produces sufficient quantities of these products to meet local demand, negating the need for imports.
