Former Argentine president Cristina Fernández de Kirchner has expanded her international legal team by adding Brazilian public law professor Rafael Valim, who will join Spanish jurist Javier Borrego — a former judge of the European Court of Human Rights — in preparing a challenge to her corruption conviction before international bodies. Kirchner was sentenced to six years in prison and permanently barred from public office for fraudulent administration in the awarding of road construction contracts in Santa Cruz province (a Patagonian region of Argentina), a conviction upheld by Argentina's highest courts. The team is weighing two possible routes — the Inter-American human rights system or United Nations mechanisms — though neither body has the power to overturn a national court ruling, meaning the most they could achieve is a declaration of state responsibility and an order for reparations.
