  • Victory in Civil Rights Case - On November 21, 2023, in a landmark civil rights verdict in United States District Court, WERKSMAN JACKSON & QUINN LLP partner Caleb Mason secured a resounding win in federal lawsuit against two police officers for excessive force and fabrication of evidence. The lawsuit, Toland v. McFarland, No. 2:21-cv-4797-FWS, alleged that a Pasadena Police Department officer pulled a Pasadena resident out of his car during a traffic stop, and then punched him repeatedly in the head, threw him to the ground, Tased him, and choked him; that the officer then falsely accused the man of attacking him; and that a second officer, who was present on the scene and saw the incident, went along with that false story and submitted a fabricated report accusing the man of attacking the other officer, despite knowing (as she later admitted) that in fact she never saw the man do anything violent or threatening whatsoever. Because of the officers’ false statements, the man was charged with battery on a police officer, charges that were later dismissed.

    The jury unanimously found that the officers used excessive force and fabricated evidence. We asked the jury to speak as the conscience of the community and say loudly and clearly that this behavior is beyond the pale, and the jury did, awarding $2.6 million in compensatory and punitive damages.

    We are a criminal defense firm. But as this case proves, when we uncover official misconduct in the course of defending a criminal case, we are ready and willing to seek justice for our clients in civil litigation as well, to ensure that our justice system works fairly and constitutionally for all.
  • Victory for public-sector unions. In September 2023, Caleb won a significant appellate case in the Ninth Circuit for his client, a police officer, on the issue of public employees’ rights to sue their employers in federal court to remedy violations of their constitutional rights. The employer, a Nevada city, had claimed that the union’s collective bargaining agreement had implicitly waived the employees’ rights to sue under federal civil rights law and that all such claims were subject to arbitration—despite the absence of any such waiver language in the agreement. The Ninth Circuit rejected the city’s arguments, and reiterated that a collective bargaining agreement does not create a waiver of the right to sue for a civil rights violation unless it says so explicitly, clearly, and unmistakably. Caleb’s client’s case for First Amendment retaliation will now proceed in federal court.

  • Dismissal of Charges in Tax Evasion Case. Caleb’s client was a 74 year-old businessman charged with tax evasion by the U.S. Attorney in Los Angeles. The client contended that he had done nothing wrong, and had relied on the advice of his accountant, who was also his transactional attorney. Caleb learned that the prosecution and IRS agents had repeatedly contacted and interviewed that attorney and sought information about the client, potentially in violation of attorney-client privilege. Because they did not record those interviews, there was uncertainty about exactly what was said, so Caleb sought an evidentiary hearing, and called the agents, the prior attorney, and ultimately even the prosecutor to testify about their interactions with the prior attorney. Caleb’s questioning revealed inconsistencies between the investigation reports and the in-court testimony, and the prosecution dismissed the case. The client is spending his golden years with his family, rather than in federal prison.
  • Dismissal of All Charges Against Three LAPD Officers. Werksman Jackson & Quinn LLP Partner Caleb Mason took on the case of three LAPD officers accused of filing false reports based on their use of the term “admitted” on field interview cards when describing an individual’s perceived gang affiliations. Caleb put on a lengthy and detailed preliminary hearing case, with testimony from 15 witnesses, including the officers themselves, regarding the meaning and use of those terms in the Department at the time, and the relevant practices, training, and policies taught to officers. On February 8, 2022, Judge Michael Pastor of Los Angeles County Superior Court ruled that the evidence showed that the officers did not commit any crimes and dismissed the charges. The Court found that “all the witnesses acknowledged that there are a great number of varying interpretations” of what the term “admitted” meant within the LAPD, that the interpretation of the term in the Department included an array of non-verbal observations as well as research into an individual’s prior contacts and social media, and that the officers acted consistently with their training in using the term as they did on the cards. The Court ruled that “overwhelming evidence supports this court’s conclusion that the officers did not have the specific intent to make false statements and did not make false statements and did not have a fraudulent or deceitful purpose.” The Court noted that “the dereliction, if there is one, does not lie with them. It lies higher up in the command structure, perhaps to the highest levels.” And the Court commented that “there’s a notion of trickle-down responsibility in this case, namely that the rank and file Metro officers are being prosecuted based upon interpretations in later years that were, in fact, made and encouraged by higher ranking individuals at LAPD.” The Court dismissed all the charges, finding that the officers “are not culpable on any count in this case.”

    Caleb, and the entire firm, are proud to represent these officers, who want nothing more than to serve and protect the people of this City as they’ve done for the past decade.

  • Charges dismissed. Client was charged with assaulting police officers following a traffic stop. In fact, the evidence revealed that the client had been subjected to excessive force and repeatedly beaten and choked. Ultimately, the defense investigation revealed that the police department had withheld exculpatory evidence, and the prosecution dismissed the charges.
  • Acquittal in federal case alleging drug trafficking conspiracy. On April 23, 2020, Werksman, Jackson & Quinn partner Caleb Mason obtained an acquittal for our client, a private charter pilot, on all charges in a federal criminal trial on drug trafficking charges in the U.S. District Court in Lexington, Kentucky. Our firm represented a private jet charter pilot who was charged by the U.S. Attorney's Office in Kentucky after one of his former charter clients was caught smuggling drugs on a private plane in Lexington, Kentucky. Our client had nothing to do with that flight, but the government charged him, and the owner of the charter company he flew for, on conspiracy charges, claiming that all of this charter client's prior flights had been drug flights, and the pilot and company owner must have known about it. A second pilot, and a business associate of the drug smuggler were also charged. The government claimed that the defendants were part of a massive multi-year conspiracy to smuggle huge quantities of drugs around the country using private planes. The trial lasted seven weeks, continuing all through the coronavirus lockdown, with more than 50 witnesses. The jury deliberated for eight days, and then acquitted our client of all charges. He is now free to return home to his wife and young daughter.
  • Conviction vacated, case dismissed. Caleb’s client was serving a 14-year sentence for drug trafficking when Caleb took on the case for appeal. Caleb attacked the evidence underlying the identification of the client and the credibility of the case agent. After protracted litigation in the Ninth Circuit and the District Court, the government agreed to vacate the conviction and dismiss the case. The client walked free and went home to his wife and three young children.
  • $2.26 million judgment for false arrest. Caleb’s client had been falsely accused by her neighbor, a sheriff’s department detective, of attempting to run over the neighbor’s daughter with her car. She was arrested, lost her job, and faced years in prison based on the accusation. Video evidence proved that the accusation was meritless, and the court issued a judgment of factual innocence in favor of Caleb’s client. Caleb then filed a civil rights lawsuit under 42 U.S.C. section 1983, alleging that the accusation was malicious and retaliatory, and part of a long-running dispute between the neighbors after Caleb’s client had complained to the sheriff’s department that the detective was parking her cars in the client’s driveway, and driving across her driveway and lawn, so she wouldn’t have to move her cars in her own driveway. Caleb’s client was so afraid of her neighbor after the false accusation that she was driven out of her own house and forced to relocate. The evidence at trial showed that the detective had intervened with a sheriff’s department sergeant after the initially responding deputies had determined that no arrest was necessary—a fact which had not been mentioned in the arrest reports. After trial in federal district court, the jury found that the detective had maliciously used her official authority to procure Caleb’s client’s wrongful arrest, and awarded damages of $2.265 million, one of the largest civil rights judgments of the year.
  • Charges dropped, client declared factually innocent by court. Caleb is one of only a few lawyers in California who have won multiple contested motions for a judicial determination of factual innocence under Penal Code section 851.8. Being accused of a crime brings a lot of collateral consequences, even if the charges are dropped or the defendant is acquitted. Section 851.8 is the only way for a person accused of a crime to obtain a final court order finding that he or she is actually innocent of the charges. But the motions are very rarely granted, because the law sets a very high standard, essentially the converse of the “beyond a reasonable doubt” standard in a criminal prosecution: the petitioner has to prove based on the evidence that no reasonable person could believe he committed the offense alleged. Courts very rarely grant the motions, particularly when the prosecution opposes them. And the prosecution almost always opposes them, even when it drops the charges or loses at trial. Caleb is one of only a few lawyers in California who has prevailed in factual innocence motions over government opposition, and he’s done so in high-profile cases. Here are three examples:
  • Caleb’s client was a high-profile entertainer accused of sexual assault. Caleb investigated the case and coordinated with the DA’s office and the LAPD, urging them to drop the case based on evidence of factual innocence. The DA ultimately agreed. Caleb then sought, and won, a judicial determination of factual innocence under Penal Code section 851.8.
  • Caleb’s client was a retired police officer accused of sexual assault and kidnapping, and facing a possible life sentence. Caleb investigated the case and was able to prove—based on analysis of street-surveillance-camera footage he was able to obtain from the city—that the allegations were not consistent with the facts. He attacked the DA’s case at a day-long preliminary hearing, following which the DA decided to drop the case. Caleb then marshalled that forensic evidence and sought, and won, a judicial determination of factual innocence under Penal Code section 851.8.
  • Caleb represented three Los Angeles police officers charged by the District Attorney’s Office with making false statements. The case generated headlines and campaign talking points, but Caleb proved at a lengthy preliminary hearing that the facts did not support the charges. In fact, as the court found, his clients neither intended to nor did make any false statements. After securing dismissal of the charges, Caleb filed a motion for a judicial finding of factual innocence, which the court granted in May 2022 despite the prosecution’s opposition.
  • Client acquitted on First Amendment defense. Caleb’s client was a political blogger charged with making threats against FBI officials on his blog. The FBI arrested him in a predawn raid and held him in custody for a year before trial. His only alleged crime was his political speech. Caleb took on the case and mounted a First Amendment defense at trial. He put on evidence, including expert-witness testimony from a tech-industry journalist, showing that the types of statements and images that the government charged as “threats” were in fact ubiquitous in social media political discussions. He cross-examined multiple FBI agents, and established that they hadn’t closely or fully read the client’s blog, or placed it in context, and that the client had never done anything “threatening” other than post the blog. Caleb argued to the jury that the First Amendment has to protect speech we don’t like to hear-- vulgar, unpopular, rude, and offensive speech. Constitutional rights protect the marginalized and outcasts, the least among us. The jury acquitted Caleb’s client on some counts, and deadlocked on the remaining ones. The judge ordered the client released immediately, and the government dropped the remaining charges.

  • Improper supervised release violation sentence reversed, clear rule established for all releasees. Caleb’s client was finishing a period of federal supervised release. On the last day before the term expired, her probation officer called her in and told her he was going to try to have her sent back to custody for allegedly violating the terms of her supervised release. He filed his petition that day, and then, weeks later, filed another petition making dozens of new allegations. Caleb was appointed to represent the client on appeal, and he challenged the probation officer’s actions. He argued—in a case of first impression in the Ninth Circuit—that the government could not bring new and unrelated violation charges after the supervised release term had ended. He argued the case before a panel of Ninth Circuit judges, and the court agreed, in a published decision that now protects the rights of all federal defendants throughout the western United States.

  • Firefighters’ First Amendment rights vindicated in high-profile retaliation cases. Caleb has represented firefighters’ unions around Southern California, including two high-profile civil-rights lawsuits alleging that city officials retaliated against the unions and their members for exercising their First Amendment rights to engage in political speech and organization. City officials were alleged to have instituted meritless, retaliatory disciplinary investigations against union leaders, cancelled promotions and promotional exams, refused (during a major wildfire season) to allow firefighters to deploy with wildfire crews, and secretly surveilled and video-recorded union members around the firehouse. Both cases settled on the eve of trial after a long and hard-fought discovery process. In one case, the City of Downey settled with the union and its members for $3.7 million. In the other case, the City of La Verne settled with the union and its members for $5.5 million.

  • Felony threat charges dropped in high-profile case. Caleb represented a client in a high-profile case involving alleged death threats phoned into a mosque, just before the 2016 election. Caleb investigated the case and found significant evidence indicating that the client had been misidentified and was not, in fact, the caller, and the government dismissed the threat charge.

  • Complete defense judgment in large financial fraud case. Caleb defended a major financial institution in a multi-million dollar fraud case. After a lengthy trial, the court found in favor of Caleb’s client on all counts.
  • Settlement for family of jail inmate who committed suicide. Caleb represented the family of a jail inmate who hung himself in a holding cell while a jailer sat in the next room on the other side of a glass window. The case alleged that the City and the private company that was contracted to run the jail failed to properly monitor the inmate and provide him with proper protection and treatment. The case settled for a confidential amount.
  • Negligent homicide cases. Caleb has represented multiple clients charged with negligent homicide after being involved in fatal car accidents. He has secured dismissals or no-custody probation dispositions for every one.
  • Case dismissed in fraud and embezzlement case. Caleb represented the family members of a business executive who was alleged to have embezzled money from her company. The company sued the family members for receipt of stolen property, alleging that the executive had used company money to pay credit card bills for various expenses that benefited the family members. Caleb challenged the legal grounds for the suit, arguing that even if the allegations were true, the facts couldn’t support tort liability for the family members. After Caleb filed his brief, the company dropped all its claims against his clients.
  • Case dismissed in inheritance dispute. Caleb represented a client who was embroiled in an inheritance dispute with a sibling. The sibling demanded a bigger share of the inheritance, and then filed a lawsuit accusing Caleb’s client of sexually assaulting him more than forty years earlier. Caleb challenged the suit in court, arguing that it was a transparent attempt to extort more money from the inheritance. The court agreed, dismissed the suit with prejudice, and imposed monetary sanctions on the sibling.
  • Supervised release term reduced, entire fine returned by government. Caleb took on the appeal for a client who had been given a lifetime term of supervised release and a large fine for a non-violent offense. Caleb challenged the sentence on appeal, and during the proceedings, the government agreed to return the fine payment to the client, reduce the supervised release term to ten years, and allow the client to emigrate to Israel, where he is a citizen, immediately upon his release. The money is now waiting for the client, to support his fresh start and new life.
  • Sentence vacated where court did not allow client to speak at sentencing. Caleb took on the appeal for a client charged with minor participation in a white-collar crime. The sentencing judge interrupted the client when he began his sentencing statement by apologizing to the court, and told the client that his apology was “b.s.” The client stopped speaking. Then the prosecutor stood up and made additional accusations. The client never got another chance to speak for himself. Caleb took the appeal and argued that the client had been deprived of his constitutional and statutory right to speak on his own behalf at sentencing. The Ninth Circuit agreed with Caleb’s argument, vacated the sentence, and remanded the case for resentencing before a different judge. The client received a reduced sentence on remand, and is now free and back with his family.
  • Judgment against MySpace for illegally sharing client’s data. Caleb represented a client who had filed a pro se lawsuit against MySpace alleging that it illegally shared his private data with the government without a warrant. Instead of defending itself in the suit, MySpace argued that it wasn’t liable because its parent company had shifted its assets around through a series of shell companies, and that the “MySpace” that the client had sued had, in the interim, ceased to exist. Caleb investigated and researched a host of corporate records and public filings, and laid out for the court the whole history of the company’s maneuverings. The company, the court ultimately stated, had acted like “an 8-year-old playing hide and seek,” and entered a judgment for Caleb’s client.

  • Pro bono cases. Caleb has taken on numerous pro bono cases over the years, and achieved significant results for his clients. For example:
  • Caleb successfully challenged the deportation of a Chinese man who had converted to Mormonism and feared persecution in China.
  • Caleb took on the appeal of a woman whose husband and three children were U.S. citizens, but who had not become a citizen herself. After her husband died, the government sought to deport her to Mexico, despite the fact that her three minor children were U.S. citizens who had never lived in Mexico. Caleb successfully challenged the deportation order in the Ninth Circuit, and the client was granted residency.
  • In another case, Caleb successfully challenged a deportation order against an Indonesian woman who sought asylum due to religious persecution. The government had changed her hearing date in a letter sent by regular mail, moving it to an earlier date. Like most immigrants, she didn’t have a lawyer, and when she appeared for the originally set hearing date, she was told that she’d already been ordered deported. The immigration court then rejected her written statement that she didn’t receive the notice, for failure to follow technical pleading requirements. Caleb took her case pro bono to the Ninth Circuit, and won, establishing a precedent that the if the government sends immigrants notices by regular mail, it is not entitled to a presumption of receipt, and that the government cannot reject pro se submissions based on technical pleading rules.

  • In another case, Caleb represented a prisoner who sued pro se because he was denied dental care for months, while suffering in agony with abscesses that prevented him from eating. The government claimed there weren’t enough dentists available in the area to call anyone in—despite the fact that the prison was located just outside Las Vegas, a major city with plenty of dentists. The trial court sided with the government, but Caleb took the case on appeal in the Ninth Circuit and won.
  • Workplace discrimination and harassment cases. Caleb has also represented plaintiffs alleging workplace discrimination—including, for example, a female electrician who was the only woman at a large construction site and alleged that she was sexually harassed by her supervisor; female creative employees at a large ad agency who alleged harassment and discrimination in pay—and has represented and advised companies responding to discrimination and harassment claims. And he has represented companies and business owners in numerous contract and business-litigation disputes.
  • Victim’s rights cases. Caleb has represented crime victims as a Marsy’s Law attorney, defending their rights and interests in criminal proceedings, including multiple victims in a high-profile torture and abuse case. And he has represented numerous plaintiffs in section 1983 civil-rights cases, challenging abuses of power by government officials, including cases of excessive force, sexual assault by law enforcement officers, and retaliation against public employees.
  • Expert witness and legal scholarship. Caleb has also served as an expert witness in drug smuggling cases, and has published dozens of articles on criminal law and procedure, including the first empirical study of the labor market for cross-border drug mules, based on a large-scale analysis of data drawn from thousands of arrests and prosecutions along the U.S.-Mexico border. And his article applying the second verse of Jay-Z’s “99 Problems” as a Fourth Amendment training tool has been adopted by educators and agencies across the country, in high school and college curricula, casebooks and textbooks, bar review and continuing legal programs, and law enforcement academies and training programs. Caleb also serves as a commissioner on the police commission (civilian oversight panel) for the City of Claremont, California.
