Richard D. Clay was convicted of murder in Missouri and sentenced to death.
See Clay v. Bowersox,
Clay’s supplemental petition argued that the State of Missouri violated his rights under the Due Process Clause of the Fourteenth Amendment, as construed in
Hicks v. Oklahoma,
After this court granted a certificate in
Goodwin,
the Supreme Court of Missouri explained that Clay “received proportionality review in the manner provided by law at the time of that review,” and that proportionality review as provided in the recent
Dorsey
decision “is not to be applied retrospectively.” Order,
State v. Clay,
No. SC78373 (Mo. Dec. 9, 2010). In light of this explanation by the Missouri court, we conclude that Clay has not made “a substantial showing of the denial of a constitutional right,” 28 U.S.C. § 2253(c)(2), as required for the issuance of a certificate of appealability, see
Miller-El v. Cockrell,
The Supreme Court in
Wainwright v. Stone,
The application for a certificate of appealability is denied, and the appeal is *999 dismissed. The motion for stay of execution is denied.
Notes
. The Honorable Dean Whipple, United States District Judge for the Western District of Missouri.
. The Anti-Terrorism and Effective Death Penalty Act restricts the authority of a district court to consider "second or successive” habeas corpus applications under 28 U.S.C. § 2254, and it requires authorization from a court of appeals before a second or successive application may be filed in the district court. 28 U.S.C. § 2244(b). The State took the position in the district court that "Clay’s claim is not 'second or successive' under 28 U.S.C. § 2244(b) because he was not able to raise his claim in his original habeas petition.” R. Doc. 81, at 1 n. 1. As in
Jones
v.
Roper,

F.3d 923, 924-25 (8th Cir.2002) (per curiam), we assume this point for purposes of analysis. See
