In U.S. v. Shalhoub the court addressed the issue of whether the denial of a motion for special appearance of counsel to seek the dismissal of an indictment on the ground that the defendant is a fugitive from justice is an immediately appealable collateral order. If not then the issue becomes whether the court should issue a writ of mandamus to compel a ruling on the motion to dismiss the indictment without requiring the defendant to appear.
This is how the facts unfold. Shalhoub, a citizen and resident of Saudi Arabia married a woman in Miami in 1985 and divorced four years later. A Florida judge gave Shalhoub and his ex-wife full shared parental responsibility over their only child. Shalhoub was indicted in 1997 for one count of parental kidnapping in violation of the International Parental Kidnapping Crime act, which made it a crime to remove a child from the United States with intent to obstruct the lawful exercise of parental rights. He was never arrested and status was fugitive.
In 2015, Shalhoub filed a motion in Miami federal criminal court to allow his counsel to appear specially and seed a dismissal of the indictment arguing that the incitement lack factual specificity, challenge the Venue of the federal kidnapping law as contravening the laws of Saudia Arabia, along with other challenges.
