A foreign government enters into a contract with a US company to provide computer equipment and services for the intelligence arm of its military forces. After the equipment has been supplied, the foreign government refuses to pay. The US company files suit in federal court in the United States, seeking to attach a US bank account owned by the foreign government. The foreign government claims that the US court has no jurisdiction and that even if it does, the government is immune from suit. What is the result?
Would the result be any different if the US company had maintained its own equipment on a lease basis abroad and the foreign government had then expropriated the equipment and refused to pay the US company its just value?
