A federal grand jury investigating possible criminal violations of the Racketeer Influenced and Corrupt Organizations Act (18 U.S.C. §§ 1961 — 1968 (1982)) (RICO) by former Philippine President Ferdinand Marcos and his wife issued subpoenas requiring the Márcoses to provide handwriting and voice exemplars and fingerprints, and to sign forms authorizing the release of confidential banking records. The Márcoses refused to comply with the subpoenas and were held in civil contempt. On appeal, the U.S. Court of Appeals for the Second Circuit (per Cardamone, J.) affirmed the contempt order and held that (1) the current Government of the Philippines had effectively waived whatever head-of-state immunity the Márcoses might have otherwise enjoyed; (2) United States law governed the Márcoses’ privilege against self-incrimination, rather than the arguably broader provisions of Philippine law; and (3) the trial court had the authority to enforce the grand jury’s order requiring the Márcoses to waive foreign financial secrecy laws.
