Vallejos v Commissioner of Registration
Justice Johnson Lam Man-hon of the CFI had been expected to rule on the case on 29 September 2011. However, the Hong Kong Observatory raised tropical cyclone warning signal No. 8 due to the approach of Typhoon Nesat early that morning, meaning that government offices closed for the day. The next morning, the weather had returned to normal, and Lam announced his ruling that the relevant provision of the Immigration Ordinance was inconsistent with the Basic Law. Vallejos herself did not attend court that day, as she was at work.
Juan Mari Brás
Based on the federal court ruling in "Colón v. U.S. Department of State" (1998), years after the U.S. State Department accepted his renunciation, Juan Mari Brás was notified on June 4, 1998, by the U.S. Department of State, that they were rescinding their acceptance, and refused to accept Mari Brás's renunciation, determining he could not renounce his United States citizenship as he did not request another national citizenship, and he was born and remains living and working in Puerto Rico. "Colón vs. U.S. Department of State" became a landmark case and is posted on the U.S. State Department's webpage.
