¶ 1 Noel Omar Rios (“Rios”) filed an
An-ders
appeal from his convictions and sentences for murder in the second degree, aggravated assault, and discharge of a firearm at a structure. Rios filed a supplemental brief in
propria persona
arguing,
inter alia,
that the superior court committed fundamental error by instructing the jury that he had the burden to prove a justification defense despite 2006 Sess. Laws. ch. 199 (“Chap. 199”) (shifting the burden of proof on justification defenses to the State). Although the superior court’s ruling was correct when made,
see Garcia v. Browning,
FACTUAL AND PROCEDURAL HISTORY
¶ 2 The State charged Rios with first degree mui’der, aggravated assault, discharge of a firearm at a structure, and assisting a criminal street gang in November 2005. Rios pled not guilty to all charges.
If 3 The two victims, Driver (the murder victim) and Passenger (the aggravated assault victim) were driving in the vicinity of Rios’s home. Rios testified they pulled their track in front of Rios’s home and had a verbal altercation with Rios’s friends and relatives, who were outside the home. Rios stated he noticed the conflict, heard the victims threaten his brother, retrieved and loaded his AK-47, and confronted the victims. Rios fired several rounds at their track and at least one hit the vehicle, penetrated the truck and severed Driver’s spinal cord, which ultimately killed him. The vehicle sped away and crashed, resulting in minor injuries to the Passenger.
¶ 4 Rios testified that not only did he hear the victims threaten to kill his brother, he believed that they would harm his brother, and fired only because he feared that they would use deadly force against him and his family. Rios stated he believed that the victims would become violent because he knew they often carried guns and that they had fired weapons at people on multiple occasions. He also testified they had committed assaults with other deadly weapons, including a baseball bat and a beer bottle, and Rios’s brother had already been attacked by the victims numerous times. Rios also stated he knew that the victims had motive to kill on that night because they were seeking revenge for a recent injury to one of their relatives.
¶ 5 Rios’s brother testified that he heard one of the victims threaten to shoot him. He also testified that Passenger’s hand, which was hanging out the window, appeared to be or was holding a firearm, that the victims regularly carried firearms, and that their reputation for violence in the community caused him to take their threat to kill him seriously.
¶ 6 Another witness bystander testified that the victims threatened to kill someone. 2 He also recounted that during the altercation, the Passenger appeared to reach for a gun.
¶ 7 Rios requested the court to instruct the jury that the State had the burden to disprove the justification defense based upon Chap. 199, amending Arizona Revised Statutes (“A.R.S.”) section 13-205 (2003) by requiring the State to disprove justification defenses beyond a reasonable doubt. 3 Rios argued that the amendment applied retroactively to conduct occurring before it became effective. The superior court rejected Rios’s argument and determined that the 2006 amendment applied prospectively only. Accordingly, the court instructed the jury that Rios had the burden of proving his justification defenses by a preponderance of the evidence.
¶ 9 While this appeal was pending, the Arizona Supreme Court decided in
Garcia
that Chap. 199 did not apply to cases in which the underlying conduct was committed before the statutory change took effect, that is before April 24, 2006.
¶ 10 In response to Garcia, in 2009 the Legislature enacted Chap. 190, which provides:
Section 1. Applicability
Laws 2006, chapter 199 applies retroactively to all cases in which the defendant did not plead guilty or no contest and that, as of April 24, 2006, had not been submitted to the fact finder to render a verdict. Section 2. Purpose
The purpose of this act is to clarify that the legislature intended to make Laws 2006, chapter 199 retroactively applicable to all cases in which the defendant did not plead guilty or no contest and that were pending at the time the bill was signed into law by the governor on April 24, 2006, regardless of when the conduct underlying the charges occurred.
ANALYSIS
¶ 11 On appeal, Rios argues that the superior court’s refusal of a burden of proof instruction reflecting the changes made by Chaps. 199 and 190 is fundamental error and that retroactive application of the amendment is within the Legislature’s constitutional power. 5 The State argues that Chap. 190, which gave retroactive effect to the statutory amendment in Chap. 199, violates Article III of the Arizona Constitution.
¶ 12 To the extent possible, we avoid deciding constitutional issues if the case can be resolved on non-constitutional grounds.
Jeter v. Mayo Clinic Ariz.,
[W]here the valid parts of a statute are effective and enforceable standing alone and independent of those portions declared unconstitutional, the court will not disturb the valid law if the valid and invalid portions are not so intimately connected as toraise the presumption the legislature would not have enacted one without the other, and the invalid portion was not the inducement of the act.
Selective Life Ins. Co. v. Equitable Life
As
surance Soc’y,
¶ 13 Before toning to the constitutional issue, we first address whether Chaps. 199 and 190 apply to this case and whether any error in instructing the jury was fundamental in nature. Because we answer both of those questions in the affirmative, we then turn to the constitutional issue presented.
I. Chapters 199 and 190 Apply to This Case
¶ 14 To the extent Chap. 190 is constitutional, it makes Chap. 199 applicable to this ease. Here, the case had not been submitted to the jury as of April 24, 2006 and Rios had not pled guilty or no contest.
II. Any Instructional Error Was Fundamental
¶ 15 On this record, the improper burden of proof instruction went to the foundation of the case and caused Rios prejudice.
See State v. Henderson,
¶ 16 In this case, that holding is especially apt. A fail’ reading of the record indicates that the primary trial issue was the applicability of justification defenses, for which the defendant presented substantial evidence. Given the quantum of evidence involved, including testimony by the defendant and multiple corroborating witnesses supporting his justification defense, we think there is a substantial probability that the burden of proof instruction impacted the verdict.
See Henderson,
III. Chapter 190 is an Exercise of the Legislature’s Constitutional Power . to Retroactively Grant Relief From Criminal Punishment
¶ 17 This appeal comes to us on unique grounds. Generally, the Legislature has the power to retroactively apply a statute granting criminal defendants a more lenient burden of proof on justification.
Garcia,
A. Underlying Principles and Test for Separation of Powers
¶ 18 While separation of powers is “explicitly and firmly expressed” under
¶ 19 When it comes to evaluating the checks and balances provided by separation of powers between the legislative and judicial branches, we look to see whether the legislative act “ ‘unreasonably limits or hampers’ the judicial system in performing its function.”
Prentiss,
¶ 20 To implement these goals, we evaluate separation of powers claims by examining “(1) the essential nature of the power being exercised; (2) the Legislature’s degree of control in exercising the power; (3) the Legislature’s objective; and (4) the practical consequences of the action.”
San Carlos Apache Tribe v. Superior Court,
B. Application of the Test to Chap. 190
¶ 21 Applying the above test, we hold that Chap. 190 did not usurp or encroach upon judicial functions by making the new burden of proof retroactive. First, the essential nature of the power at issue here is legislative. The Legislature has plenary power to determine what conduct is criminal.
State v. Ramsey,
¶ 22 Second, the limited nature of the Legislature’s enactment of Chap. 190 weighs in favor of not finding a separation of powers violation. A statute that leaves the judiciary free to make its own determination based on the particular facts of a ease comports with separation of powers.
Phoenix Newspapers,
¶ 23 Thii’d, the Legislature’s objective in Chap. 190 is mixed. By making Chap. 199 retroactive, the Legislature did not seek to take over a judicial function, but to decriminalize particular conduct and shift the burden of proof, a legislative prerogative. The key question in detei’mining the legislative objective is whether the Legislature is attempting to exei’t control over another bi-anch of government.
Woods,
¶ 24 The fourth factor is the practical impact of the particular act, if any is observable. As Chap. 190 is relatively new, we have little hard data on its impact. Its effect is limited because it only applies to cases in which the defendant did not plead guilty or no contest and that, as of April 24, 2006, had not been submitted to the fact-finder to render a decision. Moi’eover, we note that Arizona Rule of Criminal Procedure 32.1(g) has permitted a defendant to receive relief from a conviction based on l’etroactive statutory amendments for some time, and we are not aware of any evidence that the Legislature’s general exercise of that power has placed any undue burden on the judiciary. Although, as in this ease, the new law may result in a slightly increased caseload for our trial coui-ts, we do not think the effect will be so crippling as to render the law an unconstitutional encroachment on the judicial power.
¶ 25 Our conclusion is supported by common sense. When the Supreme Court decided
Garcia,
it concluded the legislature had not meant to make Chap. 199 retroactive. Thei’e is nothing in
Garcia
that hints the coui't was telling the Legislature that at no time in the future could the Legislature
¶ 26 This does not mean that the Legislature has free reign to make any law retroactive. In contrast to this case, Arizona cases striking down laws based on their retroactivity have also involved enforcing another constitutionally protected right (such as protecting a vested interest) which was infringed upon by the retroactive law. For example, in
San Carlos Apache Tribe,
the supreme court struck down a retroactive statute because retroactive application would have divested parties of rights vested prior to its enactment.
¶ 27 The State has not argued that Rios’s conviction is a vested right guaranteed to it by any part of the Arizona or federal constitutions, and we have found no authority supporting such a contention. See Adrian Ver-muele, The Judicial Power in the State (and Federal Courts) 2000 Sup. Ct. Rev. 357, 382 (2001) (“[C]riminal sentences are, of all judicial judgments, the most susceptible to revision by the political branches, so long as the revision operates in the prisoner’s favor.”)
¶ 28 The policy underlying Arizona Rule of Criminal Procedure 32.1(g) confirms that the State has no vested rights in a criminal conviction. Rule 32.1(g) allows a defendant to receive relief from a conviction if he is entitled to benefit from a retroactive change in the law, including x’etroaetive statutory amendments.
See State v. Shrum,
C. Section Two of Chap. 190 Is Not Fatal to the Entire Act
¶ 29 The State ai’gues that Chap. 190 violates separation of powers because its stated purpose is to intex-px-et existing law. We disagree. Although we agx*ee that the pur
pose
¶ 30 “As a general matter, the separation of powers doctrine leaves creation of future statutory law to the legislative branch and determination of existing law and its application to past events to the judicial branch.”
Cook v. Cook,
¶ 31 Whether a statute is ambiguous and subject to legislative clarification depends not only on the text of the statute, but on the existence of clear precedent construing the statute.
Fell,
¶ 32 Accordingly, if Chap. 190, Section Two were an attempt to clarify Chap. 199, it would violate separation of powers by attempting to interpret or construe an existing law in a fashion contrary to the Arizona Supreme Court’s construction. Section Two states that its “purpose ... is to clarify that the legislature intended to make Laws 2006, chapter 199 retroactively applicable to all eases ... pending at the time the bill was signed into law by the governor on April 24, 2006, regardless of when the conduct underlying the charges occurred.” Regardless of whether Chap. 199 was ambiguous when written, it ceased to be ambiguous once the Supreme Court interpreted it in
Garcia. Fell,
¶ 33 However, for two reasons, Section Two of Chap. 190 does not render Section One unconstitutional. First, we view Section Two as no more than a legislative comment on
Garcia,
rather than an attempt to clarify the Legislature’s intent in Chap. 199. As such, it is superfluous to our separation of powers analysis. Second, even if Section Two stated an unconstitutional purpose, we have a duty to sever unconstitutional provisions from otherwise constitutional laws when possible.
Watson,
¶ 34 Our conclusion that Chap. 190 does not violate the test for separation of powers is supported by
Enterprise,
D. State v. Montes
¶35 In
Montes,
another panel of this Court held that Chap. 190 violates separation of power principles.
¶ 36 First, this case is not like
Murray.
As explained in
Montes, Murray
dealt with a retroactive amendment to sentencing statutes to allow a court to apply flat time sentences in a pending case when the supreme court had already held in
State v. Tarango,
¶ 37 Second, as we note
supra,
part III.C, we agree with
Montes
that to the extent Section Two of Chap. 190 is interpreted as an attempt to clarify the legislative intent of Chap. 199, it would be invalid under separation of powers theory.
Montes,
¶ 38 Third, the effect of Montes is to interpret Garcia as forbidding the Legislature from at any point in the future making Chap. 199 retroactive. We cannot read that intent into Garcia and any such effect would itself raise separation of powers issues.
IV. Federal Separation of Powers Principles
¶ 39 Finally, we address one federal principle of separation of powers — the prohibition of a legislative prescription of a rale of decision in a pending judicial matter — to determine whether Chap. 190 violates that principle. We address that one principle of federal analysis because it has been applied by our supreme court in interpreting Article III,
San Carlos,
[T]he denial of jurisdiction ... is founded solely on the application of a rule of decision, in causes pending, prescribed by Congress. The court has jurisdiction of the cause to a given point; but when it ascertains that a certain state of things exists, its jurisdiction is to cease and it is required to dismiss the cause.
It seems to us that this is not an exercise of the acknowledged power of Congress to make exceptions and prescribe regulations to the appellate power.... What is this but to prescribe a rule for the decision of a cause in a particular way? ... Can we do so without allowing one party to the controversy to decide it in its own favor? Can we do so without allowing that the legislature may prescribe rules of decision to the Judicial Department of the government in cases pending before it? We think not____We must think that Congress has inadvertently passed the limit which separates the legislative from the judicial power.
Id. at 146.
¶ 41 Thus, the act of Congress condemned in
Klein
violated separation of powers by directly tying the admission of a particular kind of evidence to the result in a case without any room for judicial fact-finding and inhibiting the judiciary’s ability to determine the scope of a preexisting legal right.
¶42 Since
Klein,
the Court has distinguished and exempted from its holding eases in which a statute creates a new right and leaves the judiciary free to determine the effect of the statute and engage in fact-finding. Thus, in
Pope v. United States,
¶43 Similarly, in
United States v. Sioux Nation of Indians,
¶ 44 Although the United States conceded that the post-judgment statutory waiver of defenses did not violate
Klein
or its progeny, the Supreme Court considered the issue
sua sponte
and reached the same conclusion.
Id.
at 391-94,
¶45 More recently, the Court ruled that
Klein
does not apply when Congress merely amends applicable law.
Plant v. Spendthrift Farm, Inc.,
¶46 Finally, in
Miller v. French,
the Court analyzed
Klein’s
language and distinguished eases in which Congress merely changes the applicable legal standard.
¶ 47 Thus, while the legislative act in Klein violated separation of powers by dictating that the introduction of evidence of a pardon mandated a particular result regardless of what the evidence was, the act in Miller did not violate separation of powers because the judiciary could still enter any judgment, so long as it made appropriate findings required by the new legal standard. Id. The distinction between a statute that prescribes a rule of decision and one that merely changes the applicable legal standard is the degree of freedom that courts retain to make findings. When a statute creates a rule directly linking a particular kind of evidence to a particular result, the judicial fact-finding function is effectively eliminated. When a statute alters the legal consequences flowing from a particular set of facts, the act is within the scope of legislative power, although it may be otherwise invalid as a violation of due process or the ex post facto clause.
¶48 Arizona eases applying the rule of decision theory are similarly limited.
San Carlos
was the first Arizona ease to rely on
Klein
in separation of powers jurisprudence.
¶ 49 The statutes involved in
San Carlos,
however, are a far cry from Chap. 190. One of the statutory provisions struck down in San
Carlos
was a statute requiring that certain uses of water “shall be deemed” de minimis and mandating that a particular judgment be entered in all such eases.
Id.
at 211, ¶ 35,
¶ 50 Moreover, while the reasoning in
Montes
also relied in part on the prohibition of a legislative prescription of a rule of decision,
¶ 51 The rule against legislative prescription of rules of decision in pending cases does not require that we find Chap. 190 unconstitutional. Unlike the statutes rejected in
Klein
and
San Carlos,
Chap. 190 does not limit any court’s ability to weigh evidence or mandate any particular finding of fact based on particular evidence.
See Klein,
CONCLUSION
¶ 52 For the foregoing reasons, we hold that Chap. 190 is a valid exercise of the Legislature’s power to retroactively grant rights to criminal defendants and does not violate the separation of powers clause. We reverse Rios’s conviction and sentence and remand for further proceedings consistent with this opinion.
Notes
. Article III of the Arizona Constitution provides: "The powers of the government of the State of Arizona shall be divided into three separate departments, the Legislative, the Executive, and the Judicial; and, except as provided in this Constitution, such departments shall be separate and distinct, and no one of such departments shall exercise the powers properly belonging to either of the others.”
. While that witness had not told one of the investigating officers that fact, he did apparently tell another investigator about that threat.
. Prior to Chap. 199, section 13-205(A) provided in pertinent part: "Except as otherwise provided by law, a defendant shall prove any affirmative defense raised by a preponderance of the evidence, including any justification defense----” Chap. 199 amended 13-205(A) to read in pertinent part: "Except as otherwise provided by law. a defendant shall prove any affirmative defense raised by a preponderance of the evidence. Justification defenses ... are not affirmative defenses ... [but] describe conduct that, ... if justified, does not constitute criminal or wrongful conduct. If evidence of justification ... is presented by the defendant, the state must prove beyond a reasonable doubt that the defendant did not act with justification." Governor Napolitano signed Chap. 199 into law on April 24, 2006. It took effect immediately upon her signature because the law contained an emergency clause.
. For purposes of determining retroactivity, the court stated that the operative event is generally the date of the offense when a new statute regulates primary conduct.

. Because we grant Rios relief under the fundamental error standard, we need not consider the claim in Rios's simultaneous brief that the erroneous jury instruction is subject to harmless error analysis. We also grant Rios’s motion for leave to file a reply to the State's simultaneous brief.
. Some language in
Muiray
appears to limit the Legislature’s power to legislate retroactively, however, the context of that language indicates that it only applies in cases where retroactive application would impair substantive rights.
Murray
states that the Legislature may not " 'change the legal consequence of events completed before [a] statute’s enactment.'”
. Nor do
State v. Fell,
. As it applies to the judiciary, federal separation of powers doctrine arises out of Article III, Section 1 of the United States Constitution. See
Plaut
v.
Spendthrift Farm, Inc.,
The Supreme Court explained in
Plaut,
that separation of power violations as they relate to the judicial branch are of three types: legislative prescription of rules of decisions; legislative au
thorization of executive review of judicial decisions; and legislatively commanding courts to retroactively reopen final judgments.
. The prior law had been that the trial court could develop a rationally based exclusion from the prior appropriation system for wells having a de minimis effect on surface water. Id.
. By contrast,
San Carlos
dealt with retroactive amendments to the statutory law governing prior appropriation as due process violations rather than separation of powers violations, because they impaired existing vested rights.
