Diaz v. United States
Is it still good law? What later courts have actually done to this case.
Status
More on how this was screened
The Ninth Circuit allowed a capital defendant to waive attendance at jury selection, treating Diaz's contrary statement about capital trials as dictum. Other courts continued to apply Diaz's holdings on later homicide, confrontation, and voluntary absence from noncapital trials.
37 later cases cite Diaz v. United States; 37 of those citations sat close to treatment language and were flagged for reading, and all of them have been read. Citations that did not sit near treatment language were not flagged and were not read one by one, so a court that weakened this case without using any of that language would not appear here.

A Tennessee district court rejected Diaz's limited-jurisdiction statement and held that a state cannot avoid double jeopardy by prosecuting included offenses in separate courts.
Pettyjohn v. Evatt · E.D. Tennessee · filed
Diaz is not persuasive in this regard because this issue was not then before the Supreme Court. . . . This Court is of the opinion that states may not, by the device of creating courts of limited jurisdiction, avoid the constitutional mandate against placing a person twice in jeopardy for the same offense.

A New Mexico district court rejected Diaz's limited-jurisdiction exception to double jeopardy where the state prosecuted the same offense in separate courts.
Salaz v. Tansy · D. New Mexico · filed
The Court also held that because the lower court was without jurisdiction to try the petitioner for homicide, jeopardy did not extend to an offense beyond the court’s jurisdiction. Although this “jurisdictional exception” adopted in Diaz has not been overruled explicitly, it is inconsistent with more recent United States Supreme Court decisions establishing that successive prosecutions in different courts of the same state violate the double jeopardy clause of the Fifth Amendment. ... In light of the United States Supreme Court decisions which imply that the “jurisdictional exception” is no longer viable, New Mexico may not allow two courts within the State to place a defendant on trial for the same offense in violation of the double jeopardy clause.

The Ninth Circuit treated Diaz's capital-trial statement as dictum and permitted a capital defendant to waive his due process right to attend jury selection.
Campbell v. Blodgett · Ninth Circuit · filed
The defendant's right to be present during the trial on a capital offense has been said to be so fundamental that it may not be waived. Diaz v. United States, 223 U.S. 442, 455 [32 S.Ct. 250, 253, 56 L.Ed. 500] (1912) (dictum); ... We thus must consider whether the rule allowing voluntary waiver is applicable to capital cases. ... We conclude that allowing the defendant this choice in a capital case does not offend due process.
