Is the issue of tax arbitrable (Esso v. NNPC)?

Taxation disputes sit at a unique intersection of law where the boundaries of arbitration are clearly defined. When a company challenges a tax assessment, the law unequivocally places the authority to resolve such disputes in the hands of the court. That court serves as the guardian of government revenue and corporate taxation, recognizing the critical importance of these issues to the state’s functioning. Unlike other disputes that may be resolved through arbitration—a process prized for its flexibility—taxation is so deeply intertwined with public policy that it cannot be entrusted to private decision-making. This principle is further reinforced on a global scale, where international conventions allow countries to reject the enforcement of arbitral awards if the subject matter, like taxation, is considered non-arbitrable or if enforcing the award would conflict with public policy. This isn’t merely a legal formality; it reflects a societal decision about what issues are too fundamental to be handled outside the official judicial system. Taxation, as a cornerstone of state governance, demands resolution within the strict confines of legal authority, ensuring that it aligns with the core principles that uphold the fabric of society.
