2016年9月30日,美国公民蒂芬妮·德西蒙向华盛顿地区法庭提起针对沙特政府的诉讼。她也因此成为挑战沙特政府司法豁免权的第一位美国公民。在德西蒙提起上诉两天前的9月28日,美国国会行使了否决之否决权,推翻了奥巴马总统对一项被称为“9·11法案”的否决。这是奥巴马担任总统以来首次出现自己签署的否决案被国会推翻的情况。这是一项什么样的法律?它缘何在过去的15年中成 On September 30, 2016, U.S. citizen Tiffany Desmond filed a lawsuit against the Saudi government in Washington District Court. She also became the first U.S. citizen to challenge the Saudi government’s judicial immunity. On September 28 two days before Desmond filed his appeal, the United States Congress exercised its veto power and overthrow President Obama’s veto over a bill known as the “September 11 Bill.” This is the first time since Obama took office as the president himself signed a veto case was overthrown by the Diet. What kind of law is this? And why has it become in the past 15 years?
