Christa J. Groshek is a Minneapolis-based trial attorney who has spent more than two decades dismantling the narratives of prosecutors, police departments, and state administrative agencies. Her practice is defined by three distinct legal postures: a categorical refusal to accept the forensic and investigative orthodoxies of law enforcement; a structural commitment to resource-intensive defense tactics; and a deep fluency in both constitutional criminal law and administrative proceedings. Whether defending individuals against severe felony charges or protecting licensed professionals from bureaucratic overreach, Groshek forces powerful entities to rigorously justify their actions under the law.

The architecture of her defense practice rests on a foundation of intense preparation designed to neutralize the inherent resource advantages of the state. She views the criminal justice system and administrative tribunals not as infallible arbiters of truth, but as adversarial arenas where state narratives must be aggressively tested. By challenging unconstitutional searches, junk science, coercive police interrogations, and sanitized official reports, Groshek has established a formidable reputation as an advocate who protects clients from institutional machinery.

The Public Defender Crucible and the Tactical Parity of the “Groshek Method”

Groshek’s understanding of systemic state power was forged in the trenches of the public defense system. After graduating cum laude from William Mitchell College of Law in 2000 and clerking in the Washington County District Court, she took her first attorney position at the Legal Rights Center in Minneapolis, focusing on juvenile defense. She soon transitioned to the Hennepin County Public Defender’s Office, eventually moving from juvenile and child protection cases to the Adult Felony Trial Team.

It was on the felony trial team that Groshek developed her formidable courtroom mechanics. Handling a staggering volume of cases ranging from driving while intoxicated to first-degree murder, she tried more cases to juries in her first year than many private defense attorneys handle in a decade. Crucially, 80 percent of those first-year trials resulted in not-guilty verdicts. This statistical anomaly was not merely the result of favorable facts, but of a relentless willingness to challenge police assumptions and force prosecutors to strictly meet their evidentiary burdens.

In 2005, Groshek entered private practice, founding Groshek Law PA the following year. However, she recognized that private practice often leaves individual defendants at a severe tactical disadvantage against the limitless investigative budgets of police departments and state prosecutors. To solve this asymmetry, she developed what is now known internally as the “Groshek Method.” Implemented formally in 2018, this practice model assigns a dedicated team of three attorneys to every client and every case. By institutionalizing collaborative investigation, intense onboarding, and rigorous peer-reviewed defense strategies, Groshek ensures that no client is ever out-resourced or out-maneuvered by the state apparatus. This deliberate over-resourcing creates tactical parity, allowing her firm to dissect state narratives with exhaustive precision.

Friction at the Constitutional Boundaries: Fourth and Fifth Amendment Litigation

A core pillar of Groshek’s practice involves actively policing the boundaries of constitutional law, particularly regarding unlawful searches and seizures. She does not treat police reports as objective chronicles of events; instead, she treats them as adversarial documents requiring intense scrutiny. When law enforcement oversteps the Fourth Amendment, Groshek utilizes aggressive motion practice to suppress illegally obtained evidence, effectively dismantling the state’s case before it reaches a jury.

In a representative fifth-degree controlled substance case, a client was simply a passenger in a motor vehicle that police subjected to a routine traffic stop. After deciding to tow the vehicle, police searched the passenger without probable cause, discovering methamphetamine in his pocket. Prosecutors attempted to leverage this illegally obtained evidence to secure a felony conviction. Groshek filed a motion to dismiss, successfully arguing that the search was a blatant violation of her client’s constitutional rights. The court agreed, ruling the evidence inadmissible under the “Fruit of the Poisonous Tree” doctrine. This legal principle dictates that secondary evidence (the methamphetamine) must be excluded from trial because it stems directly from a primary constitutional violation (the illegal search), ensuring that the state cannot benefit from its own unlawful conduct. This outcome underscores her commitment to ensuring that the convenience of law enforcement never supersedes the civil liberties of the individual.

She applies this same rigorous skepticism to narratives of constructive possession—a legal doctrine where the state argues a defendant had control and intent over an illegal item without physically touching it, functionally similar to a person holding the keys to a secure safe box where contraband is stored. In a case involving a felon in possession of a firearm, police responded to reports of gunfire in North Minneapolis and stopped a vehicle. Officers found a gun under the passenger seat and immediately charged the passenger—Groshek’s client. Groshek effectively advanced the narrative that the driver had panicked and thrown the weapon at the passenger during the stop, who then instinctively kicked it under the seat to avoid possessing it. Facing a vigorous challenge to their assumptions about possession and intent, the state’s case collapsed, and the charges were dismissed following Groshek’s motion.

Groshek’s constitutional friction also extends deeply into Fifth Amendment litigation, where she actively suppresses illegally obtained confessions and exposes the prevalence of coercive police interrogations. As outlined in her legal writings, she frequently cites statistics from the Center for Wrongful Convictions indicating that false confessions factor into over one-third of juvenile exonerations, an injustice exacerbated by investigators preying on adolescent cognitive development, short-term goal focus, and prosecutorial hindsight bias. In practice, Groshek fiercely litigates Miranda violations—the constitutional imperative that suspects be informed of their right to remain silent and seek counsel before facing interrogation. For example, in the highly publicized Shante Davis case, Groshek filed motions to suppress statements after revealing through courtroom video that two Minneapolis police homicide investigators and an FBI agent used deception to lure her client into headquarters under the guise of returning a cellphone and laptop, interrogated her without Miranda warnings, and ignored her clear requests for an attorney.

Groshek is equally unafraid to challenge police narratives in physical altercations. In one notable case, her client was charged with felony assault on a police officer after using mace during an arrest. The officer testified that the client “maliciously interfered with an arrest.” Groshek countered this sanitized official narrative by presenting the client’s testimony that he was actually attempting to assist the officer in subduing a resisting individual. By reframing the incident away from the presumption of malicious interference and highlighting the chaos of the encounter, she secured a not-guilty verdict from the jury.

Dismantling Forensic Orthodoxies and Tainted Investigations

When the state charges individuals with severe, highly stigmatized offenses—such as criminal sexual conduct, child pornography, or child abuse—prosecutors heavily rely on specialized investigative units and forensic experts. Groshek recognizes that in these high-stakes arenas, challenging the state requires more than cross-examination; it requires the deployment of independent, superior scientific and forensic expertise.

In cases of alleged child abuse, the state frequently relies on diagnoses like “Shaken Baby Syndrome” or “Abusive Head Trauma”. Groshek actively collaborates with independent medical experts to challenge these state-sanctioned medical orthodoxies, demonstrating to juries that these diagnoses are often scientifically contested and insufficient to prove criminal intent beyond a reasonable doubt.

She also systematically exposes the flaws in law enforcement’s forensic interviewing protocols. In a grueling two-week criminal sexual conduct trial in Grand Marais, the state presented a highly complex, fiercely contested case. Groshek did not merely argue against the facts; she imported a forensic expert from New York to dissect the deeply flawed, suggestive interviewing techniques used by the local investigators. By educating the jury on how memory evidence can be tainted by coercive police practices, she destroyed the foundation of the state’s investigation, resulting in a complete acquittal on all counts.

Groshek’s challenge to state science extends to the technology utilized by law enforcement. She was an active member of the Minnesota Source Code Coalition, a collective of defense attorneys who pooled resources between 2007 and 2010 to challenge the infallibility of the state’s primary breath-test machine, the Intoxilyzer 5000. Through relentless federal and state litigation, the defense bar forced the manufacturer to turn over the machine’s underlying software code to independent experts. This unprecedented challenge to the state’s technological “black box” ultimately forced the Minnesota Supreme Court to acknowledge the unreliability of “deficient sample” readings, leading to the dismissal of numerous driving while intoxicated charges across the state.

Holding the State to Its Absolute Burden

Groshek’s commitment to due process is absolute, applying equally to the marginalized and the powerful. She operates on the principle that holding the state to its highest evidentiary burden is a vital public interest. This was vividly demonstrated when she was hired to defend Philip Miller, the former Benton County Attorney, against two counts of second-degree criminal sexual conduct and two counts of fourth-degree criminal sexual conduct involving a teenager.

The case was highly publicized, emotionally charged, and prosecuted by the Hennepin County Attorney’s Office to avoid local conflicts of interest. The institutional and public pressure to secure a conviction against a veteran prosecutor was immense. However, Groshek approached the defense with clinical precision, refusing to allow public condemnation to substitute for legal proof. She maintained from the outset that the charges were merely allegations unsupported by sufficient evidence.

During the two-week trial in Mille Lacs County in December 2023, Groshek systematically dismantled the state’s case. She highlighted the lack of corroborating physical evidence, contextualized the subjective testimonies of household members, and forced the prosecution to confront the absolute standard of proof beyond a reasonable doubt. After the state rested its vast, highly publicized case, the jury deliberated for a mere 90 minutes before returning a verdict of not guilty on all counts. Groshek’s defense in this matter was a masterclass in separating media frenzy from legal fact, proving that constitutional protections must not be suspended simply because the allegations are severe or the defendant is an architect of the justice system.

Checking Bureaucratic Overreach in Professional Licensure

Beyond the criminal courts, the state exerts massive control over human livelihoods through administrative agencies and licensing boards. The Minnesota Department of Human Services (DHS), the Board of Nursing, and the Board of Medical Practice possess the power to strip teachers, day care providers, social workers, and medical professionals of their careers based on administrative investigations that often lack the evidentiary safeguards of a criminal trial. Groshek aggressively defends professionals in this specialized arena, treating bureaucratic hearings with the same adversarial intensity as felony jury trials.

In the May 2019 case of Katie Sabraski, a licensed day care provider, the DHS moved to temporarily suspend her license based on an investigation into a child’s injury. The state agency alleged serious maltreatment, essentially claiming that because a stair gate had been left open, the licensee was guilty of neglect or unspecified physical abuse. The department’s report was eager to assign catastrophic blame to a minor oversight.

Groshek refused to let the state quietly steamroll her client’s livelihood. She forced an expedited hearing before Administrative Law Judge Jim Mortenson in Benton County. At the hearing, Groshek exposed the fundamental confusion and lack of evidence underlying the DHS report. The ALJ ultimately ruled completely in the licensee’s favor, declaring that there was no reasonable suspicion of physical abuse and that an open gate did not constitute an imminent risk of harm justifying a license suspension. By forcing the agency to actually prove its claims in an adversarial setting, Groshek protected a small business owner from being crushed by the disproportionate, reflexive punitive actions of a massive state bureaucracy.

Juvenile Justice: Emphasizing Human Development over State Retribution

Groshek’s foundational years in the juvenile justice system continue to heavily influence her worldview and practice. She is a staunch opponent of the punitive trend to certify juvenile offenders into the adult criminal court system—a practice that prioritizes state retribution over rehabilitation.

Having co-authored a legal reference text on juvenile criminal defense strategies, Groshek frequently argues that the legal system must view children as children. She utilizes emerging science on adolescent brain development, the emotional impact of hormonal changes, and the complicating factors of environmental trauma to fight adult certifications. When a prosecutor attempts to use Extended Juvenile Jurisdiction (EJJ)—a procedural mechanism under Minnesota law that exposes a child to a dual sentence consisting of a juvenile disposition paired with a stayed adult prison sentence that is executed if probation is violated—Groshek aggressively litigates the certification motions. Her goal is to ensure that the overarching tenets of the juvenile court—rehabilitation and restoration—are not sacrificed for the sake of public relations or prosecutorial convenience. She fights tirelessly to maintain juvenile confidentiality, recognizing that a public record can permanently derail a young life long before it has truly begun.

Ultimately, Christa J. Groshek views the law not as a tool for institutional management, but as a rigid shield for the individual. Whether she is explaining to a national Bloomberg Law audience how massive civil settlements, such as the widely publicized civil settlement awarded to George Floyd’s family (the precise dollar figures for which were not explicitly detailed in the broadcast notes but dominated national media), threaten the impartiality of criminal juries in the Derek Chauvin trial, exposing the faulty code of a breathalyzer machine, or demanding that a state agency prove its allegations against a day care provider, her methodology remains constant. She uses exhaustive preparation, superior expertise, and an unwavering commitment to civil liberties to ensure that the power of the state is constantly checked, challenged, and forced to obey the law.
