It's only two paragraphs. The first of which says that the petitioner, Nahum Gonzalez, had filed a petition asking that he not be deported, presumably because he didn't want to be sent away from his U.S. citizen wife and child. And then noting that, while the appeal was pending, Gonzalez died.
The second paragraph then says exactly what you'd expect it to say. That since the only person the deportation would affect is Gonzalez (since everyone else is already a citizen), who's currently dead, the appeal is moot.
Yep. That's right.
But thanks for the published confirmation.
