Question juridique clé
Whether the constitutional complaint could challenge the alleged violation of the federal evidentiary right and the official-duty rule in the modification proceeding.
Solution extraite
Those objections were not examinable in the constitutional complaint because they had to be raised in the parallel federal appeal.
Motifs extraits
The Federal Supreme Court held that the asserted federal-law evidentiary and official-duty complaints belonged to the appeal on points of federal law, so the constitutional complaint was barred to that extent.
