delivered the opinion of the court:
In June 2002, plaintiff, the City of Champaign (City), filed a complaint against defendant, Christian Torres, alleging he violated article 2, section 23 — 21(a), of the Champaign Municipal Code, 1985, as amended (Champaign Code) (Champaign Municipal Code, art. 2, § 23 — 21(a) (eff. April 15, 1988)), entitled “[r]esisting or obstructing a peace officer.” After an October 2002 bench trial, the trial court found defendant guilty and fined him $175 plus court costs. In November 2002, defendant filed a motion to reconsider, which the court later denied.
Defendant appeals, asserting the trial court erred in finding him guilty because the peace officer was not engaged in an “authorized act,” as required by the ordinance, when the act of resistance occurred. We disagree and affirm.
I. BACKGROUND
At the October 2002 trial, Champaign city police officer Charles Shepard testified that, on April 30, 2002, at about 2:15 a.m., he responded to a report of a loud party at 505 South Fourth Street, Champaign, Illinois, an apartment near the campus of the University of Illinois. Upon arriving, Officer Shepard stood outside the apartment *216for about 10 minutes, listening to the loud music emanating from the third-floor apartment. He then approached the apartment and knocked on its door three separate times.
At that point, defendant answered the door, opening it only to the width of his head. Officer Shepard asked defendant if he lived in the apartment, and defendant answered that he did not. The officer then asked defendant to have a resident of the apartment come to the door. Defendant agreed to do so and began to close the door. With his feet planted outside the apartment, Officer Shepard put his right arm on the door and stopped it from being shut. He then instructed defendant to leave the door open “to where it was” and repeated his request to speak with a resident of the apartment. Officer Shepard stated he was not trying to enter the apartment but wanted the door to remain open based on his experience working in the campus area. He explained that, in the past when he had allowed a door to close, the occupants would not open it again, leaving the “problem” unsolved. Defendant told Officer Shepard that he needed to shut the door before he retrieved a resident of the apartment.
Officer Shepard and defendant argued briefly about the door. At one point, defendant asked Officer Shepard if he had a search warrant, and Shepard responded no, “but [he] was not coming in.” Defendant then opened up the door widely, said “ ‘See, there’s nothing going on inside,’ ” and again attempted to shut the door. Officer Shepard put his arm “up against the door to stop it.” Defendant again stated he needed to shut the door, opened it widely, and “slammed it very hard against [Officer Shepard’s] right arm.” Officer Shepard held the door open and informed defendant he was under arrest. The officer then grabbed defendant and pulled him out of the apartment. After a brief struggle, Officer Shepard handcuffed defendant.
Officer Shepard acknowledged he crossed the threshold of the apartment when defendant struck him with the door and when he grabbed defendant from the apartment.
Defendant testified on his own behalf. He stated he was a guest at a party and voluntarily opened the apartment door when he heard a knock. Defendant also testified that he showed the officer nothing was going on and went to close the door to where it was originally when Officer Shepard placed himself in front of the door and pulled defendant out.
At the conclusion of the bench trial, the trial court found defendant guilty of the ordinance violation. In November 2002, defendant filed a motion to reconsider. After a February 2003 hearing, the trial court denied the petition. This appeal followed.
*217II. ANALYSIS
Article 2, section 23 — 21(a), of the Champaign Code provides, as follows:
“No person shall knowingly resist or obstruct the performance by one known to the person to be a peace officer for the City of Champaign of any authorized act within the peace officer’s official capacity.” Champaign Municipal Code, art. 2, § 23 — 21(a) (eff. April 15, 1988).
At issue here is the “authorized act” language, which is also contained in section 31 — 1(a) of the Criminal Code of 1961 (Criminal Code) (720 ILCS 5/31 — 1(a) (West 2002) (“Resisting or obstructing a peace officer or correctional institution employee”)). Defendant argues the officer’s order to keep the door open and his physically keeping the door open were not “authorized acts” because they violated defendant’s fourth amendment rights (U.S. Const., amend. IV).
Neither the Champaign Code nor the Criminal Code defines “authorized,” but Illinois courts have defined the term as meaning “ ‘endowed with authority.’ ” People v. Shinn, 5 Ill. App. 3d 468, 472, 283 N.E.2d 502, 505 (1972), quoting People v. Young, 100 Ill. App. 2d 20, 23, 241 N.E.2d 587, 589 (1968). That definition provides little guidance.
In State v. Gardiner, 814 P.2d 568, 574 (Utah 1991), the Supreme Court of Utah addressed whether a police officer was “acting within the scope of his authority as a peace officer” (Utah Code Ann. § 76— 5 — 102.4 (1990)) when he unlawfully entered a building to conduct a search. In interpreting the “scope of authority” language, the court looked to the Second Circuit’s decision in United States v. Heliczer, 373 F.2d 241, 245 (2d Cir. 1967), which found the appropriate test was whether an officer was doing what he or she was employed to do or was engaging in a personal frolic. Gardiner, 814 P.2d at 574. Other state supreme courts have looked to the Heliczer test in interpreting similar language. See State v. Doe, 92 N.M. 100, 103, 583 P.2d 464, 467 (1978) (“in the ‘lawful discharge of his duties’ ” (N.M. Stat. Ann. § 40A — 22—23 (Repl. 1972)); State v. Hatton, 116 Ariz. 142, 148, 568 P.2d 1040, 1046 (1977) (discharging a duty of his office (Ariz. Rev. Stat. § 13 — 541(A) (1974))).
•2 We also find Heliczer provides the appropriate test for determining whether an officer’s actions were “authorized.” The fact a police officer’s conduct is later determined to be unlawful should not divest the officer of his or her authority. See Gardiner, 814 P.2d at 575. In applying the Heliczer test, we find the evidence was sufficient to support the trial court’s conclusion that Officer Shepard was engaged in an “authorized act” when defendant forcefully closed the door on Officer Shepard’s arm.
*218The above interpretation of “authorized act” best serves the public interest. While the public has an interest in securing for its members the right to be free from unreasonable searches and seizures (United States v. Ferrone, 438 F.2d 381, 390 (3d Cir. 1971)), it also has an interest in discouraging violence and insisting on peaceable methods to resolve conflicts between citizens and their government (see People v. Pruitt, 166 Ill. App. 3d 679, 682, 520 N.E.2d 1113, 1115 (1988)). Self-help measures undertaken by an individual who objects to the legality of an entry can lead to violence and serious physical injury. See Doe, 92 N.M. at 102-03, 583 P.2d at 466-67. In fact, with resistance, violence is not only invited but can be expected. See Hatton, 116 Ariz. at 147-48, 568 P.2d at 1045-46. If an officer’s unlawful entry is an unauthorized act, an individual may lawfully resist such an entry. Such a policy fundamentally opposes a civilized rule of law. See People v. Abrams, 48 Ill. 2d 446, 456, 271 N.E.2d 37, 43 (1971).
Moreover, the “victim” of an unlawful entry is not left without recourse. Under the “fruit of the poisonous tree doctrine,” when police conduct results in a violation of a person’s constitutional rights, any evidence that the State obtains by exploiting the constitutional violation is subject to suppression. People v. McCauley, 163 Ill. 2d 414, 448, 645 N.E.2d 923, 940 (1994). Thus, officers are not encouraged to violate a person’s fourth amendment rights because any evidence obtained could be suppressed.
Accordingly, a proper accommodation of the above public interests requires a person claiming to be the subject of an unlawful entry by a peace officer to raise that claim in a court of law and not forcibly resist the officer’s entry. See Ferrone, 438 F.2d at 390.
The same policy accommodation was reached in Abrams, 48 Ill. 2d at 455-57, 271 N.E.2d at 43-44, where the supreme court declined to extend the fruit of the poisonous tree doctrine to a defendant’s acts that arise from and in reaction to unlawful police conduct. Further, while the supreme court did not discuss public policy in People v. Locken, 59 Ill. 2d 459, 464-65, 322 N.E.2d 51, 54 (1974), that holding accomplishes the same policy accommodation by holding an unlawful arrest is an “authorized act” under the resisting-or-obstructing-a-peace-officer statute (Ill. Rev. Stat. 1971, ch. 38, par. 31 — 1 (now see 720 ILCS 5/31 — 1(a) (West 2002))).
We recognize that other courts have declined to apply Locken to police conduct not involving an arrest. In People v. Villarreal, 152 Ill. 2d 368, 375, 604 N.E.2d 923, 926 (1992), the Supreme Court of Illinois stated the following:
“Defendants are correct in claiming that the crucial fact in *219 Locken was the undertaking of an unlawful arrest by a police officer, and that Locken is not relevant to obstruction of an unlawful entry into a person’s home by a known officer.” (Emphases in original.)
While it has been suggested that this language means an unlawful entry is not an “authorized act,” it is clearly dictum as Villarreal dealt with an arrest and applied Locken. See Villarreal, 152 Ill. 2d at 376-77, 604 N.E.2d at 927. Moreover, the supreme court may simply have been noting that the reasoning in Locken would not apply to an unlawful entry situation as the court based its holding on section 7 — 7 of the Criminal Code (720 ILCS 5/7 — 7 (West 2002)), addressing a private person’s use of force in resisting arrest. While that reasoning may not apply to an unlawful entry, it does not mean that an unlawful entry is not also “an authorized act.” As stated, the policy considerations are similar for both an arrest and an entry.
Moreover, we agree with the Second District’s affirmation of the trial court’s dismissal of the obstructing-a-peace-officer (Ill. Rev. Stat. 1989, ch. 38, par. 31 — 1) complaints against the defendants in People v. Hilgenberg, 223 Ill. App. 3d 286, 585 N.E.2d 180 (1991). A violation of that section requires an act of physical resistance (Pruitt, 166 Ill. App. 3d at 682, 520 N.E.2d at 1115) and, by simply not opening the door, the defendants did not engage in such an act. That alone warranted dismissal of the complaint. However, we disagree with their finding the police were not engaged in an “authorized act” when they sought entry into the dwelling to investigate a complaint of unlawful consumption of alcoholic beverage and disorderly conduct. Hilgenberg, 223 Ill. App. 3d at 294, 585 N.E.2d at 186.
Additionally, we note that in both Young, 100 Ill. App. 2d at 24-25, 241 N.E.2d at 589-90, and People v. Swiercz, 104 Ill. App. 3d 733, 736-37, 432 N.E.2d 900, 902 (1982), the First District found a police officer’s unlawful entry was not an “authorized act.” However, we are not bound to follow the decisions of other districts of the state appellate court (Lara v. Hyundai Motor America, 331 Ill. App. 3d 53, 64, 770 N.E.2d 721, 729 (2002)) and, for the reasons expressed in this opinion, we respectfully disagree with those decisions.
III. CONCLUSION
Accordingly, we affirm the trial court’s judgment.
Affirmed.
