OPINION
¶ 1 The issue presented is whether the same standard governs a trial court’s rulings on pre-verdict and post-verdict motions for judgment of acquittal under Arizona Rule of Criminal Procedure 20. We hold that the same standard applies, disаpproving of any contrary language in
State ex rel. Hyder v. Superior Court,
I.
¶ 2 Randall and Penny West were charged with child abuse after an infant in their foster care died from severe head trauma. During their joint trial, each moved for judgment of acquittal under Rule 20(a) at the close of the State’s case and after the close of evidence. The trial court denied those motions. The jury then found Randall guilty of reckless child abuse under circumstances not likely to produсe death or serious injury and Penny guilty of negligent child abuse under circumstances likely to produce death or serious injury.
¶3 After trial, the defendants timely renewed their motions for judgment of acquittal under Rule 20(b). The trial court granted the motions, finding that although “a rational trier of fact could find beyond a reasonable doubt that the victim’s injury was caused by an act of child abuse,” there was “no substantial evidence proving whether it was both or only one defendant that did so” and “no substantial evidence to establish whether either defendant permitted the injury, and, if so, which one.”
¶ 4 The court of appeals reversed.
State v. West,
¶ 5 We granted the defendants’ petitions for review to consider what standаrd governs a trial court’s ruling on post-verdict motions for judgment of acquittal under Rule 20(b), an issue of statewide importance that involves interpretation of one of our rules.
See State v. Aguilar,
II.
¶ 6 Arizona Rule of Criminal Procedure 20(a) provides that on a defendant’s motion or its own initiative, a trial court “shall enter a judgment of acquittal” before the verdict “if there is no substantial evidence tо warrant a conviction,” and that “[t]he court’s decision on a defendant’s motion shall not be reserved, but shall be made with all possible speed.” Rule 20(b) provides that “[a] motion for judgment of acquittal made before vеrdict may be renewed by a defendant within 10 days after the verdict was returned.”
¶ 7 In
Hyder,
this Court set aside the trial court’s post-verdict judgment of acquittal because the judge had cited no “legal basis” for that ruling and “gave no reasons for his finding of no substantial evidence.”
¶ 8 For several reasons, we now disapprove of the conditions Hyder placed on a trial court’s granting of post-verdict motions for judgment of acquittal under Rule 20(b). First, they are not grounded in the language of Rule 20 and, in fact, аre inconsistent with the rule when read as a whole. Rule 20(b) permits a defendant, after verdict, to renew a motion for judgment of acquittal made before verdict under Rule 20(a) and does not limit the trial judge in any way. Under subsectiоn (a), the only question is whether “there is no substantial evidence to warrant a conviction.” By imposing an additional requirement for granting post-verdict motions under Rule 20(b), Hyder departs from the rule’s language by essentially prohibiting trial judges from granting such motions even if the judge concludes that no substantial evidence supports a conviction.
¶ 9 Under Hyder, a defendant who merely “renews” his pre-verdict motion may not obtain relief under Rule 20(b). Unless the defendant can show evidentiary, legal error during trial, a post-verdict motion is futile because the judge is confined to his denial of the pre-verdict, Rule 20(a) motion. This construct conflicts with the language of Rule 20.
¶ 10 Second, Hyder's qualifications lacked any supporting authority or rationale, and case law elsewhere is to the contrary. For example, federal courts (applying Federal Rule of Criminal Procedure 29(c), the counterpart tо our Rule 20(b)) apply the same standard to both pre-verdict and post-verdict motions for judgment of acquittal.
See United States v. Rojas,
¶ 11 Third, the qualifications
Hyder
added to Rule 20(b) raise constitutional concerns. If those qualifications, strictly applied, are not met, a trial court must let a conviction stand even if it finds post-verdict no substantial evidence to warrant the conviction. But
*562
that potentiality is illogical and, more importantly, would conflict with well-settled law.
See Tibbs v. Florida,
¶ 12 Fourth,
HydeP
s limitation makes little sense from a policy and systemic standpoint. Because
Hyder
sharply limits the ability to grant a post-verdict motion under Rule 20(b), judges in close cases might err on the side of granting the defendant’s pre-verdict motion under Rule 20(a), and if so, double jeopardy principles would preclude the state from challenging that ruling on appeal.
See Smalis v. Pennsylvania,
¶ 13 In addition, unlike the limited special action procedure available to the state in
Hyder,
¶ 14 For these reasons, we disavow
Hyder
to the extent it provides that a trial court may grant a post-verdict judgment of acquittal under Rule 20(b) only if the court concludes that it “consider[ed] improрer evidence” and changes its “position on prior evidentiary rulings.”
¶ 15 This question of sufficiency of the evidence is one of law, subject to de novo review on appeal.
State v. Bible,
¶ 16 On all such motions, “the relevant question is whether, after viewing the evidence in the light most favorable to the prosecution,
any
rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.”
Mathers,
¶ 17 As we noted in
Mathers,
however, “[t]he fact that a jury convicts a defendant does not in itself negate the validity of the earlier motion for acquittal” because “[i]f it did, a jury finding of guilt would always cure the erroneous denial of an acquittal motion.”
*563
¶ 18 On the other hand, “[w]hen reasonable minds may differ on inferences drawn from the fаcts, the ease must be submitted to the jury, and the trial judge has no discretion to enter a judgment of acquittal.”
State v. Lee,
¶ 19 Finally, although Rule 20 does not require a trial court to specify reаsons for granting a post-verdict motion for judgment of acquittal, we strongly encourage judges to do so. That practice will aid the parties and appellate courts, which (on any appeal from the ruling) will reviеw de novo whether there is substantial evidence to support a conviction, applying the same standard governing trial court rulings under Rule 20.
See Bible,
¶ 20 Here, the trial judge thoroughly explained his reasons for granting defendants’ post-verdict motions under Rule 20(b). Because the court of appeals understandably reviewed the tidal court’s ruling under
HydePs
now-discarded limitation, however, the appellate court did not determine whether the record reflеcts substantial evidence to warrant the convictions. We therefore remand the case to the court of appeals to address the sufficiency of the evidence and the merits of the trial court’s granting оf judgments of acquittal under Rule 20(b).
See State v. Rabun,
III.
¶ 21 The court of appeals’ opinion is vacated and the case is remanded to that court for further proceedings consistent with this opinion.
Notes
. In view of this objective legal standard, we disavow statements in
Hyder
and other Arizona cases that a trial court’s ruling on Rule 20 motions hinges on whether the court subjectively "has a conscientious conviction that the elements of the offense have not been proven.”
Hyder,
