A magistrate found Bradley Howard Bower guilty of harassment of a public officer. On appeal, the district court, sitting as an appeals judge, affirmed the conviction and imposed a harsher sentence than that imposed by the magistrate. In this appeal, Bower claims Iowa Code section 718.4 (2003) is unconstitutional and there is not substantial evidence to support his conviction. Our review of the record indicates Iowa Code section 718.4 is constitutional and there is substantial evidence to support his conviction. Therefore, we affirm his conviction.
Bower further asserts it is impermissible for the district court to increase his sentence following his unsuccessful non-de novo appeal. Because we agree the district court’s imposition of a harsher sentence violates Bower’s due process rights, we vacate the sentence of the district court and remand the case for the district court to enter judgment for the same sentence imposed by the magistrate.
I. Facts.
On our de novo review of the facts, we find around 2:30 a.m. on November 28, 2004, West Branch police officer Jonathan Kolosik observed a red pickup truck driving the wrong way on a one-way street. Not knowing where the truck was going, Kolosik drove on the street in the proper direction in an attempt to head the truck off. By the time Kolosik noticed the truck again, it was parked in the driveway of Kyle Coleman’s residence, which is a few houses away from Bower’s home or roughly one city block. When Kolosik saw the truck in Coleman’s driveway, he also observed two people kneeling in front of the truck. Kolosik pulled over in front of the Coleman residence and the two people came over to him. Kolosik identified the two as Coleman and Jerrod Rummells. Kolosik recognized the truck as belonging to Rummells.
When speaking to Rummells, Kolosik noticed a faint smell of alcohol on him. He also saw Rummells had some marks on his hands, consistent with being in a fight. At the time of the stop, Kolosik knew a fight had occurred at a bar in a nearby community.
About ten minutes after Kolosik began talking to Rummells and Coleman, Bower walked toward the scene from his home. Kolosik, who was inside his squad vehicle at the time, exited the vehicle as soon as Bower approached.
Kolosik characterized Bower’s demeanor as threatening, irate, agitated, and very *440 angry. Kolosik testified that Bower told him “to get out of [his] area” and Kolosik “wasn’t supposed to be there.” He also testified Bower said he was “going to sue [Kolosik’s] ass,” and he “owned [Kolosik]” and “paid [Kolosik’s] salary.”
Kolosik testified he asked Bower repeatedly to leave and told him the situation did not concern him. Instead of leaving or maintaining his position some distance from Kolosik, Bower continued to move closer. At one point during the encounter, Bower was close enough for Ko-losik to smell a faint odor of alcohol on Bower. At this point, Kolosik called for backup. Seeing that the situation was escalating, Rummells intervened in the confrontation. Kolosik told Rummells to explain the situation to Bower. Rummells eventually pulled Bower away from Kolo-sik’s personal space. Rummells then talked to Bower and Bower left the scene.
With Bower now gone, Kolosik advised Rummells and Coleman to remain at Coleman’s residence because he believed they were intoxicated. However, Kolosik decided not to charge either of them with any offense. After completing his investigation, Kolosik left the scene.
II.Proceedings.
On December 10, 2004, Kolosik filed a complaint alleging Bower committed harassment of a public official in violation of Iowa Code section 718.4. Bower moved to dismiss the complaint asserting section 718.4 is unconstitutional in that it violates Article I of the United States Constitution and article I of the Iowa constitution. The court overruled the motion.
The case proceeded to trial before a magistrate. The magistrate convicted Bower. Reasoning “the statute only criminalizes conduct that interferes with an ongoing investigation,” the magistrate found the statute was not overbroad on its face or as applied. The magistrate further explained it was not Bower’s words alone that created the violation, but it was also his conduct of approaching an officer to a point at which the officer feared for his own personal safety. The magistrate sentenced Bower to pay a $100 fine plus surcharge and costs.
Bower appealed the magistrate’s decision to the district court. The district court affirmed Bower’s conviction, finding the statute criminalizes conduct rather than speech and that there was substantial evidence to support Bower’s conviction. The district court increased Bower’s sentence to a $500 fine plus costs and a suspended thirty-day jail sentence.
Bower filed an application for discretionary review, which we granted.
III. Issues.
Bower raises three issues on appeal. They are: (1) whether Iowa Code section 718.4 is unconstitutional; (2) whether there is substantial evidence to support Bower’s conviction under section 718.4; and (3) whether it is permissible for the district court to increase Bower’s sentence following his unsuccessful non-de novo appeal.
IV. Scope of Review.
Our review is de novo when we assess an alleged violation of constitutional rights.
State v. Shanahan,
In regards to Bower’s claim as to the sufficiency of the evidence supporting
*441
his conviction, our review is for correction of errors of law.
State v. Leckington,
Finally, “[w]e review the district court’s sentence for correction of errors at law.”
State v. Freeman,
V. Analysis.
A. Constitutional challenges.
The State convicted Bower for violating Iowa Code section 718.4. Section 718.4 provides: “Any person who willfully prevents or attempts to prevent any public officer or employee from performing the officer’s or employee’s duty commits a simple misdemeanor.” Iowa Code § 718.4. We have said “ ‘statutes are cloaked with a presumption of constitutionality.’ ”
State v. Seering,
The Due Process Clause of the United States Constitution provides the State shall not “deprive any person of life, liberty, or property without due process of law.” U.S. Const, amend. XIV, § 1. The Due Process Clause prohibits vague statutes.
State v. Musser,
Vague statutes offend several important principles.
Grayned v. City of Rockford,
First, because we assume that man is free to steer between lawful and unlawful conduct, we insist that laws give the person of ordinary intelligence a reasonable opportunity to know what is prohibited, so that he may act accordingly. Vague laws may trap the innocent by not providing fair warning. Second, if arbitrary and discriminatory enforcement is to be prevented, laws must provide explicit standards for those who apply them. A vague law impermissibly delegates basic policy matters to policemen, judges, and juries for resolution on an ad hoc and subjective basis, with the attendant dangers of arbitrary and discriminatory application. Third, but related, where a vague statute “abut[s] upon sensitive areas of basic First Amendment freedoms,” it “operates to inhibit the exercise of [those] freedoms.” Uncertain meanings inevitably lead citizens to “ ‘steer far wider of the unlawful *442 zone’ ... than if the boundaries of the forbidden areas were clearly marked.”
Id.
at 108-09,
1. Vague as applied.
Bower asserts section 718.4 is vague as applied under the state and federal constitutions. In determining whether the statute is vague as applied, “we focus on whether the defendant’s ‘conduct clearly falls “within the proscription of [section 718.4].” ’ ”
Musser,
When interpreting statutes, we have said:
“The goal of statutory construction is to determine legislative intent. We determine legislative intent from the words chosen by the legislature, not what it should or might have said. Absent a statutory definition or an established meaning in the law, words in the statute are given their ordinary and common meaning by considering the context within which they are used. Under the guise of construction, an interpreting body may not extend, enlarge or otherwise change the meaning of a statute.”
State v. Gonzalez,
Section 718.4 criminalizes conduct that “willfully prevents or attempts to prevent any public officer or employee from performing the officer’s or employee’s duty.” Iowa Code § 718.4. “Willfully,” as used in section 718.4, means intentionally, deliberately, and knowingly because preventing or attempting to prevent a public officer or employee from performing the officer’s or employee’s duty is commonly understood to be morally questionable, or an action unjustifiably endangering persons or property.
See State v. Azneer,
We have not had the opportunity to define the term “prevent” as used in section 718.4. The dictionary, however, contains several applicable definitions of the word “prevent,” including “to deprive of power or hope of acting, operating, or succeeding in a purpose: frustrate, circumvent”; “to keep from happening or existing esp. by precautionary measures: hinder the progress, appearance, or fulfillment of: make impossible through advance provisions”; “to hold or keep back (one about to act): hinder, stop”; “to act or come before”; “to make something impossible.” Webster’s Third New International Dictionary 1798 (unabr. ed.2002).
Finally, a police officer is a public officer. Thus, section 718.4 criminalizes intentional conduct that hinders or attempts to hinder a police officer from performing the officer’s duty.
Applying this construction of the statute to the facts, Bower’s conduct clearly falls within the proscription of section 718.4. Although Bower argues the only thing he did that evening was to shout at Kolosik, *443 we find Bower did more. In addition to shouting at Kolosik, Bower intentionally approached Kolosik and entered his personal space. Kolosik perceived Bower’s actions as threatening. Bower’s conduct was done intentionally to hinder or to attempt to hinder Kolosik from conducting a lawful investigation.
Section 718.4 gives fair warning that a person should not willfully hinder or attempt to hinder an officer from conducting a lawful investigation. Bower should have known that intentionally entering the personal space of an officer would hinder an officer from completing a lawful investigation. Consequently, section 718.4 is not vague as applied to Bower, who entered the personal space of Kolosik in a threatening manner while Kolosik was conducting a lawful investigation.
2. Overbreadth.
Bower also asserts section 718.4 is overbroad. Normally a person lacks standing to make a facial challenge to a statute, if a statute can be constitutionally applied to that person’s conduct.
Musser,
“[T]he overbreadth doctrine permits the facial invalidation of laws that inhibit the exercise of First Amendment rights if the impermissible applications of the law are substantial when ‘judged in relation to the statute’s plainly legitimate sweep.’ ” Musser;
Bower argues section 718.4 is overbroad because “it prohibits
any
interruption of official duties by
any
means.” Bower asserts “it is well-settled that verbally preventing a public official from carrying out his or her duty is not sufficient to constitutionally criminalize speech.” In making this argument, Bower relies on the Supreme Court’s decision in
City of Houston v. Hill.
In
Hill,
while the police were investigating a situation, the defendant shouted, “Why don’t you pick on somebody your own size?”
Id.
at 454,
In an attempt to save the ordinance from this constitutional defect, the City argued the Supreme Court should abstain from deciding the case until the state court had a chance to construe the ordinance.
Id.
at 467,
In applying the
Hill
analysis to the present case, we start with the premise that unlike the situation in
Hill,
this court has the power to construe state statutes narrowly to comply with the constitutional right of free speech.
Grayned,
B. Sufficiency-of-the-evidence challenge. Bower claims there is insufficient evidence to support his conviction under section 718.4. He contends the State did not prove Kolosik was engaged in an official duty at the time of the altercation or that Bower’s nonverbal conduct prevented Kolosik from carrying out his duties. We disagree.
In reviewing a sufficiency-of-the-evidence claim, “ ‘we view the evidence in the light most favorable to the State’ ” and determine whether substantial evidence supports the verdict.
State v. Hoskins,
The question here is whether Bower willfully prevented or attempted to
*445
prevent Kolosik from performing his duty. First, viewing the evidence in the light most favorable to the State, a rational trier of fact could be convinced beyond a reasonable doubt that Kolosik was performing a duty. Kolosik’s testimony supports he was conducting an investigation involving Rummells and Coleman, despite Bower’s testimony that Kolosik did not appear to be doing anything more than “shooting the breeze” and Coleman’s testimony that Ko-losik was “making small talk.”
Cf Shanahan,
Second, viewing the evidence in the light most favorable to the State, a rational trier of fact could be convinced beyond a reasonable doubt Bower willfully prevented or attempted to prevent Kolosik from performing his duty. The “willfully” aspect was supported by Bower’s testimony that he left his residence in order to go to the scene and intervene. The “prevented or attempted to prevent” aspect was supported by Kolosik’s testimony that Bower told him “to get out of [his] area,” and he “wasn’t supposed to be there,” as well as Kolosik’s testimony that Bower entered his personal space and he felt threatened by Bower’s conduct.
Therefore, there is sufficient evidence to support Bower’s conviction under section 718.4.
C. Increased sentence challenge. Bower claims it is impermissible for the district court, acting as an appeals judge, to increase his sentence following his unsuccessful non-de novo appeal. His argument that increasing his sentence violates his due process rights is dispositive of the issue.
The Supreme Court has summarized a defendant’s due process right of a “free and unfettered” appeal.
North Carolina v. Pearce,
It can hardly be doubted that it would be a flagrant violation of the Fourteenth Amendment for a state trial court to follow an announced practice of imposing a heavier sentence upon every recon-victed defendant for the explicit purpose of punishing the defendant for his having succeeded in getting his original conviction set aside. Where, as in each of the cases before us, the original conviction has been set aside because of a constitutional error, the imposition of such a punishment, “penalizing those who choose to exercise” constitutional rights, “would be patently unconstitutional.” And the very threat inherent in the existence of such a punitive policy would, with respect to those still in prison, serve to “chill the exercise of basic constitutional rights.” But even if the first conviction has been set aside for nonconstitutional error, the imposition of a penalty upon the defendant for having successfully pursued a statutory right of appeal or collateral remedy would be no less a violation of due process of law. “A new sentence, with enhanced punishment, based upon such a reason, would be a flagrant violation of the rights of the defendant.” A court is “without right to ... put a price on an appeal. A defendant’s exercise of a right of appeal must be free and unfettered.... [I]t is unfair to use the great power given to the court to determine sentence to place a defendant in the dilemma of making an unfree choice.” “This Court has never held that the States are required to *446 establish avenues of appellate review, but it is now fundamental that, once established, these avenues must be kept free of unreasoned distinctions that can only impede open and equal access to the courts.”
Id. (alteration in original) (internal citations omitted) (footnotes omitted).
Pearce
involved an appeal by two defendants. One defendant’s conviction was reversed in a state court post-conviction proceeding while the other defendant’s conviction was set aside in a state court coram-nobis proceeding.
Id.
at 713-14,
A series of subsequent rulings by the Supreme Court limited the holding of
Pearce
and restricted the presumption of vindictiveness. One of the first decisions to make inroads into the doctrine announced in
Pearce
was
Colten v. Kentucky.
Another decision limiting
Pearce’s
application involved a retrial where the second jury sentenced the defendant to a harsher sentence than the first jury.
Chaffin v. Stynchcombe,
A third decision limiting
Pearce’s
application involved a retrial where the judge sentenced the defendant to a harsher sentence than the jury gave in the first trial.
Texas v. McCullough, 475
U.S. 134, 136,
Lastly, the Supreme Court analyzed a case where a defendant successfully overturned his guilty plea and proceeded to a trial.
Alabama,
We have had an occasion to examine this body of jurisprudence in the context of a retrial, where a judge sentenced a defendant to a harsher sentence than the original judge did after the first trial.
State v. Mitchell,
In applying these principles to the present case, it is first necessary to determine the review Bower received. The Iowa rules of criminal procedure govern the procedure when appealing a magistrate’s decision. In this case, Bower appealed the magistrate’s decision to the district court. The rules require the district court to decide the appeal on the record, if the court finds the record adequate to determine whether substantial evidence supports the findings of fact in the original proceeding. Iowa R. Crim. P. 2.73(3). If the record is adequate and substantial evi *448 dence supports the findings of fact, the findings are binding on the judge deciding the appeal. Id. If the court finds the record inadequate to determine whether the findings of fact in the original action are supported by substantial evidence, the judge may order presentation of further evidence on appeal. 2 Id. Additionally, “[t]he judge deciding the appeal may affirm, or reverse and enter judgment as if the case were being originally tried, or enter any judgment which is just under the circumstances.” Id.
In Bower’s appeal, the district court did not order any further evidence to be presented. Therefore, we assume the record was adequate for the court to determine whether substantial evidence supports the findings of fact in the original proceeding. Consequently, the district court reviewed the magistrate’s decision for correction of errors at law.
In making a correction-of-errors-at-law review, such as the district court did in this case, the reviewing court’s function is to determine whether substantial evidence supports the findings made by the lower court, not whether the evidence might support different findings.
Fischer v. City of Sioux City,
Under the decisions of the Supreme Court, a defendant’s due process rights are not violated if a second court imposes a harsher sentence than the first court, so long as the second court reconsiders the evidence, finds its own facts, and provides logical non-vindictive reasons for imposing the harsher sentence. In the present case, the district court did not reconsider the evidence, make its own findings of fact, or provide the defendant with logical non-vindictive reasons for imposing a harsher sentence. Consequently, it was improper for the district court to impose a harsher sentence. 3
*449 VI. Disposition.
Because Iowa Code section 718.4 is constitutional and there is sufficient evidence to support Bower’s conviction under section 718.4, we affirm Bower’s conviction. We do find, however, that the district court’s imposition of a harsher sentence violates his due process rights. Consequently, we vacate the sentence of the district court and remand the case for the district court to enter judgment with the same sentence imposed by the magistrate.
JUDGMENT OF CONVICTION AFFIRMED, SENTENCE VACATED, CASE REMANDED WITH DIRECTIONS.
Notes
. At the time Klees was decided, the statute provided on appeal "[t]he cause shall stand for trial anew in the district court in the same manner that it should have been tried before [the lower court].” Iowa Code § 762.48 (1971), repealed by 1972 Iowa Acts ch. 1124, § 282.
. When before a magistrate, our rules of criminal procedure allow for a record to be made electronically or by minutes of testimony prepared by the magistrate if either party does not provide a court reporter at that party’s expense. Iowa R. Crim. P. 2.67(9). The record could be inadequate if the recording is inaudible or the minutes are incomplete. Under these circumstances, the appeals judge could order further testimony, resulting in a different type of review.
. This conclusion is consistent with our state’s public policy governing resentencing on appeals from the district court to our appellate courts. The Code provides in an appeal from the district court an appellate court may reduce punishment on appeal, but may not increase it. Iowa Code § 814.20;
