not voidable, but simply void, and this even prior to reversal. Elliott v. Peirsol, 1 Pet. 328, 344; Old Wayne Mutual Life Association v. McDonough, 204 U. S. 8.
Which of the propositions shall prevail in a given case cannot be dogmatically asserted, and cases of their consideration and application can be cited against each other. There is such citation in the pending case. Plaintiff in error cites among others, McCormick v. Sullivant, 10 Wheat. 192; Des Moines Navigation Co. v. Iowa Homestead Co., 123 U.

McCormick v. Sullivant involved the effect of diversity of citizenship, and it was decided that an absence of its allegation did not impeach the judgment rendered in the case and preclude its being conclusive upon the parties. And ii;,was said (as it has often been said), that the courts of the United States aré “of limited jurisdiction; but they a,re not, on that account, inferior courts, in the technical sense of those words, whose judgments, taken alone, are to be disregarded. If the jurisdiction be not alleged in the proceédings, their judgments and decrees are erroneous, and may, upon writ of error or appeal, be reversed for that cause. But they are not absolute nullities.”
In Des Moines Navigation Co. v. Iowa Homestead Co., 123 U. S. 552, there came up to be considered also the effect of a prior adjudication as dependent upon an allegation of diversity of citizenship, and the ruling in McCormick v. Sullivant was affirmed.
The immediate comment on these cases is that the courts had jurisdiction of their subject-matter and necessarily power to pass upon the fact (diversity of citizenship) upon which that jurisdiction depended in the given case. The subject-matter of the suit was not withheld from them by explicit provision of the law which was their sole warrant of power.
Denver First National Bank v. Klug is nearer to the
