State Courts and De Novo Review
The majority of state courts follow the U.S. Supreme Court and independently review mixed questions of federal constitutional law and fact.
There is some scholarly debate over the source of the Court’s power to mandate application of its appellate standards of review when it is not explicitly stated by the Court. Compare Henry P. Monaghan, Harmless Error and the Valid Rule Requirement, 1989 Sup. Ct. Rev. 195, 200 n.30 (arguing that the Court’s authority rests on constitutional common law), and Henry P. Monaghan, The Supreme Court, 1974 Term—Foreword: Constitutional Common Law, 89 Harv. L. Rev. 1, 20–21, n.112 (1975) (discussing the distinction between true constitutional rules and constitutional common law), and Daniel J. Meltzer, Harmless Error and Constitutional Remedies, 61 U. Chi. L. Rev. 1, 1–5 (1994) (agreeing with Monaghan on theory of constitutional common law), with Russell M. Coombs, A Third Parallel Primrose Path: The Supreme Court’s Repeated, Unexplained, and Still Growing Regulation of State Courts’ Criminal Appeals, 2005 Mich. St. L. Rev. 541, 591–96 (questioning argument that source of power comes from constitutional common law).
Nonetheless, nearly all state courts have agreed that “[i]t is well settled that de novo review is ordinarily appropriate in cases where constitutional rights are implicated.” State v. Diaz, 372 N.C. 493, 498, 831 S.E.2d 532, 536 (2019) (citing Ornelas). State courts have usually followed the SCOTUS precedent without discussion, either because they found its holdings binding or because they recognized that their own precedents are consistent. While not a comprehensive state-by-state review, the following illustrates the breadth of adoption of de novo review.

There have been, as is always the case, a few exceptions. See, e.g., State v. Brockman, 339 S.C. 57, 528 S.E.2d 661, 665 (S.C. 2000) (finding Ornelas not binding); Guzman v.

Thurman, 846 P.2d 1256, 1266–67 (Utah 1993) (“We are aware that we must follow federal standards of review when expressly mandated to do so by Congress or the United States Supreme Court as a matter of substantive federal law. However, absent such a mandate, we think that the standard of review is a question to be determined by the law of the forum performing the appellate review.”). Such cases, however, are few and far between. And at least in the Texas case, Guzman, the isolated holding is inconsistent with other Texas opinions cited above.
Conclusion
Practitioners may rely on the overwhelming weight of the authorities reviewed above to argue that state appellate courts should follow the U.S. Supreme Court in applying a de novo standard of appellate review in cases presenting mixed issues of federal constitutional law and fact.
