This is a very interesting case regarding immigration and obtaining citizenship through a U.S. citizen parent. Basically, this case used Article 314 of the Mexican Constitution when determining whether to deport individuals who claim American citizenship.
In Mexico, Saldana was born to an American male and a Mexican female. His birth certificate listed both parents. DHS deported him and denied his citizenship application on the basis that he was born out-of-wedlock.
According to DHS, Article 314 provided that children born out of wedlock can only be legitimized if the couple marries subsequently. At oral argument, however, the government admitted that Article 314 did never existed. DHS then cited Article 130 alleging it required marriage for legitimacy of children.
The Fifth Circuit Court of Appeals held in their opinion disagreed. Article 130 merely cited that marriage was a civil contract, rather than a religious one. In addition, the court noted that this article said nothing about the legitimization of children. The court explained,
In sum, under the laws of Tamaulipas, Mexico, where Saldana was born and resided as a child, he was acknowledged by his father when his father placed his name on the birth certificate before the Civil Registry. As an acknowledged child, Saldana had the same filial rights vis-a-vis his father as a “legitimated” child.
