Gabon's main opposition figure, Alain-Claude Bilie-By-Nze, will remain in detention after the Libreville Court of Appeal on June 2 rejected his bid to invalidate legal proceedings. Detained since April 16, Bilie-By-Nze faces investigation for alleged breach of trust and fraud dating back to 2008, accusations his legal team argues are legally prescribed. His lawyers have denounced the decision as a violation of Gabonese law and fair trial guarantees, calling for his immediate release and alleging irregular arrest circumstances. President Brice Oligui Nguema denies executive interference, asserting judicial independence. Bilie-By-Nze, a former prime minister and presidential election challenger, had publicly criticized the government.
