OPINION
On January 26, 1988, petitioner filed an application for a writ of prohibition and/or mandamus to prevent the Honorable Respondent from conducting a capital resen-tencing trial under 21 O.S.Supp.1985, § 701.13(E)(2), in Oklahoma County District Court, Case No. CRF-79-105. On January *377 27, 1988, this Court stayed the proceedings and directed a response from the Honorable Respondent or his authorized representative. On February 5, 1988, Oklahoma County Assistant District Attorney Ray Elliott and Legal Intern Kayce Gisinger filed a response brief on behalf of, and as authorized by, the Honorable Respondent. Oral argument was held on February 11, 1988. Subsequently, upon order of this Court, both parties filed supplemental briefs on February 16, 1988. The Attorney General’s Office was granted leave to file an amicus curiae response and supplemental brief.

PROCEDURAL BACKGROUND
Petitioner was tried by jury and convicted of first degree murder and sentenced to death in May, 1979. Petitioner’s attorneys of record, J. Malone Brewer and William Smalley, were removed in 1981 and 1982 respectively for failure to prosecute the mandatory appeal. Petitioner’s current attorney, James W. Berry, filed a brief in November, 1982, and the case was argued in 1983. Petitioner’s first degree murder conviction and sentence of death was affirmed on direct appeal in a unanimous opinion authored by former Judge Tom Cornish.

OKLAHOMA’S CAPITAL RESENTENCING STATUTE
In 1981, Oklahoma’s Mandatory Capital Sentence Review Statute provided that this Court shall be authorized to affirm the sentence of death or “[s]et the sentence aside and remand the case for modification of the sentence to imprisonment for life.”
Where errors have occurred during the sentencing stage of a capital trial, with
*378
one recent exception,

we have consistently modified the death sentence to life imprisonment on the basis of
I write separately only to emphasize that it is our State statute, not the United States or Oklahoma Constitution, which prohibits resentencing of this appellant. As Judge Brett has explained in the course of his opinion,21 O.S. 1981 , § 701.13(E) allows this Court one remedy only if error has tainted the validity of the sentencing stage of trial, and that is to modify the sentence to life imprisonment. The Attorney General’s public policy arguments against this statute are therefore better, addressed to the Legislature, rather than this Court.
Effective July 16, 1985, the Oklahoma Legislature amended Section 701.13(E), to authorize this Court to affirm a death sentence or “[s]et the sentence aside and remand the case for resentencing by the trial court.” 21 O.S.Supp.1985, § 701.13(E). In
Green v. State,
The
Green
decision was later overruled by a majority of this Court, but only to the extent that it refused to retroactively apply the 1985 amendment to 21 O.S.1981, § 701.13(E) deleting proportionality review.

EX POST FACTO LAWS
The United States and Oklahoma Constitutions prohibit the passage of ex post facto laws. U.S. Const. art. I, § 10; Okla. Const. art. II, § 15. As Justice O’Connor recently noted:
Our understanding of what is meant by ex post facto largely derives from the case of Calder v. Bull,3 Dall. 386 ,1 L.Ed. 648 (1798), in which this Court first considered the scope of the ex post facto prohibition. In Calder, Justice Chase ... summarized his understanding of what fell ‘within the words and intent of the prohibition’: 1st. Every law that makes an action done before the passing of the law, and which was innocent when done, criminal; and punishes such action. *379 2d. Every law that aggravates a crime, or makes it greater than it was, when committed. 3d. Every law that changes the punishment, and inflicts a greater punishment, than the law annexed to the crime, when committed. 4th. Every law that alters the legal rules of evidence, and receives less, or different testimony, than the law required at the time of the commission of the offense, in order to convict the offender. Id., at 390 (emphasis omitted) (citations omitted)
Miller v. Florida,
482 U.S. -, -,
The application of the 1985 amendment to Section 701.13(E) providing for resen-tencing following the finding of second stage errors on appeal to petitioner clearly involves a retrospective application of the law. Respondent concedes that petitioner’s death sentence would be modified to life imprisonment under the former sentence review statute which was in effect at the time petitioner committed the acts leading to his conviction. Brief of Respondent, at 2. Accordingly, the retrospective requirement has been met here.
Respondent argues that because the deletion of proportionality review was viewed as a procedural change in
Brewer
and
Foster,
then the provision for resentencing must likewise be viewed as procedural. Respondent contends that the amendment to Section 701.13(E) is procedural in nature, and that a procedural change “is not ex post facto even though it may work to the disadvantage of a defendant.
Hopt v. Utah,
[E]ven if a law operates to the defendant’s detriment, the ex post facto prohibition does not restrict ‘legislative control of remedies and modes of procedure which do not affect matters of substance.’ Dobbert,432 U.S., at 293 ,97 S.Ct., at 2298 . Hence, no ex post facto violation occurs if the change in the law is merely procedural and does ‘not increase the punishment, nor change the ingredients of the offence or the ultimate facts necessary to establish guilt.’ Hopt v. Utah,110 U.S. 574 , 590,4 S.Ct. 202 ,28 L.Ed. 262 (1884). See Dobbert, supra, at 293-294,97 S.Ct., at 2298 ... On the other hand, a change in the law that alters a substantial right can be ex post, facto ‘even if the statute takes a seemingly procedural form.’ Weaver,450 U.S., at 29, n. 12 ,101 S.Ct., at 964, n. 12 .
Miller,
482 U.S. at -,
Respondent and
amicus curiae
argue that petitioner will not be deprived of a substantial right, because at the time of the commission of the offense the punishment for first degree murder was life imprisonment or death and, on resentencing, the punishment is life imprisonment or death. If we were to accept the respondent’s contention, however, we would have to ignore the following holding in
Lindsey v. Washington,
To answer [the question of whether a later standard is more onerous than the earlier one] we compare the practical operation of the two statutes as applied to petitioners’ offense ... [T]he ex post facto clause looks to the standard of punishment prescribed by a statute, rather than to the sentence actually imposed. The Constitution forbids the application of any new punitive mea *380 sure to a crime already consummated, to the detriment or material disadvantage of the wrongdoer ... It is for this reason that an increase in the possible penalty is ex post facto ... regardless of the length of the sentence actually imposed, since the measure of punishment prescribed by the later statute is more severe than that of the earlier ... (citations omitted) (emphasis added).
Clearly, if the statute in effect at the time of the commission of petitioner’s offense is applied, in view of the second stage error, petitioner’s death sentence would automatically be modified to life imprisonment. 21 O.S.1981, § 701.13(E)(2);
Green,
We believe respondent’s reliance on
Dobbert v. Florida,
Respondent also relies on
State v. Norton,
*381
We hold that the retroactive application of the 1985 resentencing amendment of Section 701.13(E)(2) to petitioner would constitute a violation of the Federal and Oklahoma Constitutions as an
ex post facto
application of a law which “inflicts a greater punishment than the law annexed to the crime at [the] time it was committed or alters [the] situation of [an] accused to his disadvantage.”
Spitznas v. State,
IV.
STATUTORY CONSTRUCTION
Finally, with regard to statutory construction and retroactivity, both parties were directed to address the applicability of 22 O.S.1981, § 3 which provides: “No part of this code is retroactive unless expressly so declared.” Respondent and amicus curiae argue that because the resentencing statute is codified in Title 21 at 21 O.S. Supp.1985, § 701.13(E)(2), and Title 21 is the Penal Code, Section 3 of Title 22, the Code of Criminal Procedure, is not applicable. Respondent and amicus curiae point out that the words “this code” are expressly defined to mean Oklahoma statutes only in Title 22 and not in Title 21. Title 21 O.S.1981, § 2 provides: “No act or omission shall be deemed criminal or punishable except as prescribed or authorized by this code. The words ‘this code’ as used in the ‘penal code’ shall be construed to mean ‘Statutes of this State.’ ”
We are not persuaded by this argument. First, it places form over substance. The problem with this position is that respondent and amicus curiae want to label the resentencing statute as being procedural for purposes of determining the ex post facto issue, but not for the purpose of determining the application of 22 O.S.1981, § 3. We do not believe that the State can have it both ways. Second, by its own terms, Title 22 “applies to criminal actions....” 22 O.S.1981, § 8.
The 1985 resentencing amendment contains no language, express or implied, indicating that it was intended to be applied retroactively.
Compare
Ark.Stat.Ann. § 41-1358(e) (Supp.1985). “It is well established that unless a legislative enactment by its very own language is to apply retroactively, it can apply prospectively only.”
Freshour v. Turner,
Relying on the Utah Supreme Court’s reasoning in
State v. Norton,
There appears to be no good reason for excluding ... remedial statutes, from the general rule, that retroactive or retrospective legislation is not favored, in the absence of any words expressing a contrary intention. Undoubtedly, the legislature may declare a statute dealing with remedial legislation, or one not affecting vested rights, to have a retroactive operation. It is reasonable to conclude that the failure to express an intention to make a statute retroactive evidences a lack of such intention.

CONCLUSION
For all of the foregoing reasons, we find that petitioner has met his burden of showing the necessary requirements for the issuance of a writ of prohibition.
See James v. Rogers,
Notes
. This Court may independently reweigh aggravating and mitigating circumstances where one of several aggravating circumstances has been invalidated, in order to determine the factual substantiation and validity of a death sentence under 21 O.S.1981, § 701.13(F), and whether the death sentence is arbitrary or capricious after the invalid aggravating circumstance is removed.
