Société des Mines de Loulo S.A. v. Republic of Mali
ICSID · Investment (ICSID and treaty) · Mali · 2 Jun 2016
Why it matters
This case is a landmark example of an ICSID tribunal enforcing a contractual stabilization clause against a sovereign state's tax measures. It clarifies the scope of stabilization clauses in investment contracts, particularly regarding indirect taxes and benefits-in-kind. The decision also addresses the interaction between domestic tax law and international arbitration, reinforcing the binding nature of fiscal stability commitments in mining agreements.
Summary
Société des Mines de Loulo S.A. (Somilo), a Malian gold mining company, brought an ICSID claim against the Republic of Mali under the Establishment Convention signed in 1993, which contained a stabilization clause guaranteeing Somilo a stable fiscal regime. Mali issued two tax adjustments (2008 and 2012) imposing additional taxes on Somilo, including VAT withholding, IBIC withholding, and taxes on benefits-in-kind. Somilo argued these violated the stabilization clause. The Tribunal upheld jurisdiction, rejecting Mali's objections including premature filing and lack of treaty. On the merits, the Tribunal found that the stabilization clause protected Somilo from new or increased taxes not provided for in the Convention. It held that the IBIC withholding and penalties on VAT withholding breached the clause, as did the housing tax and inclusion of certain benefits-in-kind in the tax base. However, the VAT withholding itself was not a breach. The Tribunal ordered Mali to pay damages for amounts already collected, plus interest at the ECB rate plus 2%, and declared Mali unjustified in pursuing further recovery on those items. Costs were allocated 70% to Mali and 30% to Somilo. The case underscores the enforceability of stabilization clauses in investment contracts.
