The evidence strongly and consistently supports the statement. A majority of the provided sources, including a high-authority legal analysis from the New Civil Liberties Alliance and multiple independent news reports, directly state that a U.S. appeals court ruled the FBI was not liable for the alleged destruction of a Bitcoin hard drive. Several sources identify the specific court as the U.S. Court of Appeals for the Eleventh Circuit and the case as involving plaintiff Michael Prime. The high-authority source provides the legal context, discussing the case under the Federal Tort Claims Act and federal immunity. The remaining relevant sources, despite varying in authority, all corroborate this central fact without any contradiction. Sources that were irrelevant to this specific case were disregarded.
