A young Arizona woman was left with bloody abrasions after a police encounter beside a palm tree. Years later, federal judges examined whether the officer responsible had violated her constitutional rights during an arrest.
The controversy began around midnight on June 22, 2016, in Tucson, Arizona. Police officers approached Bassilea Mena and her boyfriend after hearing the couple arguing while standing on a median between busy streets.
What initially appeared to be a routine police encounter quickly escalated. Officers questioned the couple, and when Mena failed to produce identification, Officer Robert Massey moved to detain and handcuff the young woman.
Mena was approximately twenty-two years old. According to the officer’s account, she had been uncooperative, appeared intoxicated, and resisted attempts to control her movements while officers investigated the disturbance.
But Mena described the encounter very differently. She alleged that Massey became angry after the handcuffs pinched his hand and deliberately shoved her face-first into a nearby palm tree during the arrest.
The contact left scratches and abrasions on her face and shoulders. Photographs documented the injuries, which would later become important evidence when federal judges examined whether the officer’s use of force was legally justified.
Massey denied deliberately attacking her. He maintained that Mena twisted her arms and pulled away while he attempted to apply handcuffs, causing her to come into contact with the palm tree.
The disagreement created two fundamentally different versions of the same event. Under Mena’s account, an officer intentionally used unnecessary force. Under Massey’s account, the injuries resulted from a difficult handcuffing encounter.
One year later, on June 22, 2017, Mena filed a civil rights lawsuit against Massey. The case proceeded in the United States District Court for the District of Arizona, where both accounts faced examination.
Mena challenged the legality of her detention and arrest, as well as the force used against her. Massey defended his conduct and argued that qualified immunity protected him from personal liability.
Qualified immunity can shield government officials from civil liability when their conduct does not violate clearly established constitutional rights. The doctrine became central because the parties disputed what had actually happened beside the tree.
On January 8, 2019, the district court granted summary judgment in Massey’s favor on Mena’s unlawful seizure and false arrest claims. Her excessive force allegation, however, presented a different problem for the court.
The judge concluded that disputed facts prevented a decision granting Massey qualified immunity on the excessive force claim. The disagreement over whether he deliberately shoved Mena required careful consideration rather than simply accepting his explanation.
Massey appealed that decision before the underlying lawsuit had reached a jury. His interlocutory appeal brought the controversy before the United States Court of Appeals for the Ninth Circuit.
On January 22, 2020, the case reached oral argument before a federal appellate panel. Massey was represented by Tucson City Attorney Dennis McLaughlin, while Mena’s case was presented by law student Damian Gallagher.
Gallagher was a third-year student at William & Mary Law School, appearing under attorney supervision. His participation added an unusual dimension to a hearing already centered on difficult questions of police authority.
McLaughlin began by defending the officer’s claim to qualified immunity. He argued that existing legal precedent had not clearly established that Massey’s conduct, under the particular circumstances, violated the United States Constitution.
But the judges quickly challenged the reasoning. One questioned whether constitutional protection required a previous case involving the identical kind of tree, contrasting a palm tree with a hypothetical pine tree.
The question exposed a central problem in qualified immunity litigation. Courts must examine whether an established legal principle clearly prohibited the officer’s conduct without requiring every possible factual variation to have appeared in earlier cases.
McLaughlin emphasized that the officers had encountered an uncooperative woman standing on a dangerous street median. He argued that moving her away from traffic and physically securing her was a legitimate safety measure.
The judges acknowledged the importance of officer and public safety. However, they repeatedly distinguished the ordinary act of handcuffing a suspect from the separate allegation that Massey deliberately pushed Mena against the tree.
Under the woman’s account, the officer had used force that was not necessary to accomplish the arrest. The distinction mattered because a court reviewing summary judgment could not simply reject her evidence.
The judges also questioned the injuries visible in photographs. One observed that many people are handcuffed without suffering cuts requiring medical attention, challenging the suggestion that such injuries were an unavoidable consequence.
McLaughlin responded that Mena’s injuries had received limited medical treatment and emphasized that an injury alone did not automatically establish excessive force. His argument focused on the circumstances confronting the officer.
Yet another judge raised an uncomfortable procedural question. If the accounts were genuinely disputed, why not allow a jury to decide what happened instead of pursuing an appeal that could prolong litigation?
The comment went directly to the nature of the case. Massey might ultimately persuade jurors that his version was accurate, but an appellate court reviewing the immunity ruling faced different legal constraints.
Those constraints required the judges to consider whether Massey would be entitled to immunity even if Mena’s account were accepted. They could not settle the disputed encounter by choosing which witness seemed more believable.
McLaughlin continued insisting that the relevant constitutional boundaries had not been sufficiently clear in 2016. He pointed toward the absence of earlier decisions addressing an encounter with precisely comparable circumstances.
The court remained skeptical. Existing law already recognized limits on unnecessary force against people who posed little threat, and the judges questioned whether the supposed factual differences justified removing Mena’s claim from consideration.
After the officer’s attorney finished his initial presentation, Gallagher stood to address the panel. His argument focused on whether established Fourth Amendment protections prohibited significant force against someone who was not actively resisting arrest.
The law student’s position was straightforward. He argued that Mena had already been under the officer’s control when Massey allegedly shoved her into the tree after the handcuffs pinched his hand.
Gallagher described the alleged movement as a deliberate thrust rather than a normal consequence of handcuffing. He pointed toward the visible injuries and the absence of evidence that Mena posed an immediate danger.
The judges questioned how courts should determine whether force was significant enough to violate constitutional protections. They also asked whether the relatively limited severity of Mena’s injuries weakened her legal argument.
Gallagher emphasized that the Fourth Amendment inquiry concerned the reasonableness and necessity of the force used. The existence of physical injuries could inform that assessment without automatically determining the constitutional question.
He also highlighted the minor nature of the suspected offense. Mena had been arrested in connection with allegedly failing to provide her true name, rather than an accusation of serious violence.
The defense challenged the circumstances surrounding that accusation. Gallagher argued that Massey had asked Mena for physical identification rather than directly requesting her name, an important distinction under the relevant Arizona law.
But the appellate hearing was not deciding whether the original arrest had been unlawful. The remaining central question involved the force used during handcuffing and the officer’s entitlement to qualified immunity.
Gallagher relied on earlier Ninth Circuit cases addressing force against individuals who offered limited resistance. He argued that these decisions provided sufficient warning that officers could not use substantial unnecessary force.
One important precedent was Graham v. Connor, the Supreme Court’s landmark 1989 decision establishing an objective reasonableness standard for evaluating excessive force claims arising during arrests and investigatory stops.
Under that framework, courts consider factors including the seriousness of the suspected offense, whether the individual posed an immediate threat, and whether the person actively resisted arrest or attempted to flee.
Gallagher argued that those considerations favored Mena. She was suspected of a nonviolent offense, was not fleeing, and, under her version of events, had not engaged in resistance justifying the alleged shove.
The attorney also referred to cases including Meredith v. Erath and Gravelet-Blondin v. Shelton. Those decisions addressed constitutional limitations on force used against individuals whose resistance was minimal or passive.
The judges examined whether the cited authorities were sufficiently comparable. The question was not whether another person had previously been injured against a palm tree, but whether the governing constitutional rule was clear.
Gallagher maintained that officers could not escape liability merely because a particular method of inflicting injury had not appeared in an earlier published decision. The degree and necessity of force remained central.
His argument also stressed that Mena’s injuries included more than physical discomfort. He referred to emotional and psychological consequences, although the panel questioned the available legal support for considering those effects.
Despite those questions, Gallagher completed his presentation with a detailed defense of Mena’s constitutional claim. He asked the appellate court to uphold the district court’s refusal to grant Massey qualified immunity.
Then came an unexpected moment. One judge asked whether Gallagher was a law student and where he attended school. After hearing his response, members of the panel complimented the quality of his presentation.
The praise stood out because Gallagher was arguing against an experienced government attorney in a federal appellate courtroom. His performance had required navigating complicated legal precedent under direct questioning from three judges.
McLaughlin returned for rebuttal, arguing that the authorities Gallagher cited involved different circumstances. He stressed the potential dangers officers face during domestic disturbance investigations and repeated his position concerning clearly established law.
The judges again focused on the relatively minor charge and the disputed nature of the physical encounter. The hearing ended with the panel taking the case under consideration after thanking both advocates.
On February 26, 2020, the Ninth Circuit issued its decision. The appellate court affirmed the district court’s denial of summary judgment based on qualified immunity, allowing Mena’s excessive force claim to proceed.
The court concluded that a reasonable factfinder could consider Massey’s conduct objectively unreasonable if Mena’s description were believed. Existing precedent also sufficiently established limits on force against nonthreatening individuals offering, at most, passive resistance.
That ruling represented an important procedural victory for Mena, but it did not establish that Massey had actually violated her rights. The factual dispute still required resolution through the ordinary litigation process.
Massey sought further review by petitioning the United States Supreme Court. On January 11, 2021, the Supreme Court declined to hear the case, leaving the appellate ruling in place.
The litigation consequently returned to the district court, where the disputed facts could finally be presented to a jury. Years had passed since the original encounter on the Tucson street median.
The delay had become an important feature of the controversy. During oral argument, one appellate judge had suggested that pursuing the interlocutory appeal created substantial additional proceedings without necessarily improving Massey’s position.
The judge had even indicated that Massey might ultimately prevail before a jury. Such an outcome remained possible because jurors would be permitted to decide which account of the disputed encounter they believed.
On November 18, 2022, following a four-day trial, the jury returned its verdict. The decision favored Officer Robert Massey, rejecting Mena’s claim after hearing the evidence presented during the proceedings.
The outcome demonstrated the distinction between defeating qualified immunity at summary judgment and proving a constitutional violation at trial. The earlier appellate decision had allowed the lawsuit to continue without deciding ultimate liability.
Mena appealed again, challenging the judgment entered following the jury trial. Her case returned to the Ninth Circuit, extending a legal dispute that had already lasted several years.
On July 19, 2024, the Ninth Circuit affirmed the judgment favoring Massey. The appellate decision left the trial result intact, bringing the prolonged federal litigation to its reported conclusion.
The final outcome was therefore markedly different from the initial appellate ruling. Mena had successfully resisted dismissal of her excessive force claim, but the jury ultimately found in favor of the officer.
This distinction is essential to understanding the case. A court can determine that disputed facts justify a trial without concluding that the plaintiff’s accusations have been proven by the evidence.
The proceedings also illustrated why qualified immunity appeals can produce unexpected consequences. When immunity depends upon contested facts, appellate courts generally cannot resolve those disputes by accepting an officer’s preferred account.
Instead, the evidence may eventually need to be considered by jurors. In this case, the intermediate appeal added extensive proceedings before a jury ultimately reached a verdict supporting Massey’s position.
The case raised broader questions about police accountability and constitutional protections. Officers must make difficult decisions under pressure, but their authority to use force remains subject to legal limits and judicial scrutiny.
For Mena, the encounter became the beginning of years of litigation over injuries she attributed to deliberate police misconduct. For Massey, the proceedings involved defending his actions against a serious constitutional accusation.
Neither the initial denial of immunity nor the final defense verdict erased the fact that the parties fundamentally disagreed about what happened. The legal process ultimately determined which claims could proceed and who prevailed.
The most memorable courtroom exchange involved a deceptively simple comparison between palm trees and pine trees. Beneath that unusual question lay a fundamental issue concerning how specifically constitutional rights must be established.
Ultimately, Massey prevailed, while Mena’s excessive force claim was rejected at trial and the judgment affirmed on appeal. The lengthy proceedings revealed how disputed encounters can move through multiple levels of federal litigation.
What began as an argument on a Tucson street median became an eight-year legal dispute involving a young woman, a police officer, a law student, and fundamental questions about the constitutional limits of police force.
