Key legal question
Whether the Geneva courts had jurisdiction over a damages action against a foreign investigating judge for official acts.
Extracted holding
No; the judge was protected by state immunity because the challenged acts were sovereign judicial acts of Spain.
Extracted reasoning
The issuance of an international arrest warrant in a Spanish criminal investigation was an act of sovereign authority (jure imperii) attributable to Spain. A Swiss court may not review such conduct, and the action was therefore inadmissible in Geneva.
