Vallejos v Commissioner of Registration
Vallejos and Domingo v. Commissioner of Registration was a court case against the government of Hong Kong by two foreign domestic helpers (FDHs) seeking permanent residence and the right of abode in Hong Kong. Because of its subject matter it was commonly referred to in the media as the FDHs' right of abode case (外傭居港權案). Evangeline Vallejos and Daniel Domingo were two of five applicants who in various groups filed three right of abode lawsuits in 2010; the ruling in Vallejos' case was expected to be a precedent for the other two.
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.
