“ The review of the final judgment of the district court of the United States for Porto Rico is not restricted to those cases in which the Constitution, or a treaty of the United States, or an act of Congress is brought in question and the right claimed under it denied. This construction is too narrow and technical. There may be cases-certainly civil cases-in the United States district court for Porto Rico that do not involve any question arising under the Constitution, or a treaty, or an act of Congress ”

“ Unless the case was one in which the judgment could be reviewed here, then such judgment would be final, and not subject to review; for no case determined in the United States court for Porto Rico can be carried to a circuit court of appeals. ”
