In California, an Administrative Per Se (APS) refusal allegation is one of the most severe administrative penalties a driver can face. Under California Vehicle Code § 13353, if a driver is accused of refusing or failing to complete a chemical test (breath or blood) after a lawful DUI arrest, the Department of Motor Vehicles (DMV) imposes an automatic one-year hard suspension.
Unlike standard DUI suspensions, a refusal suspension carries no eligibility for a restricted license—no driving to work, no driving for medical needs, and no driving for family duties.
When a client found themselves facing this exact scenario following an incident on Catalina Island, top-tier Southern California DUI Defense Attorney Matthew Ruff stepped in to challenge the DMV’s case and secure a complete Set Aside of the suspension.
The Incident: An Alleged Golf Cart Rollover in Avalon
On May 31, 2026, Los Angeles County Sheriff’s Department deputies responded to a report of a flipped golf cart on Camino de Flores in Avalon, CA. By the time law enforcement arrived at the scene:
No driving had been observed by officers.
The golf cart was already pushed back onto its wheels and parked.
The alleged driver, [Client], was inside a private residential complex taking a shower.
Deputies entered the private residence without a search warrant or explicit consent, contacting [Client] inside after his shower. Based on physical observations, admissions, and field sobriety test performance, officers arrested [Client] for driving under the influence (VC § 23152(a)).
At the station, deputies processed [Client] and claimed he refused to submit to a chemical test, logging the incident as a formal Chemical Test Refusal on DMV Form DS-367.
The Legal Strategy: How Matthew Ruff Dismantled the DMV’s Case
Winning an APS refusal hearing requires an exhaustive examination of constitutional law, statutory procedure, and officer reporting errors. Long Beach DUI Attorney Matthew Ruff filed a comprehensive Memorandum of Points and Authorities, attacking the DMV’s case on three key legal fronts:
Attorney Ruff established that the initial seizure and arrest were unconstitutional:
No Warrant or Consent: Deputies entered a private residential complex and contacted [Client] inside without a search warrant or valid consent, violating Payton v. New York (1980).
No Exigent Circumstances: Under United States Supreme Court precedent (Lange v. California [2021], Welsh v. Wisconsin [1984]), the desire to investigate or preserve evidence of a misdemeanor DUI does not justify a warrantless entry into a private home.
Failure to Meet Misdemeanor Arrest Exceptions: Under California Penal Code § 836(a)(1), an officer cannot make a warrantless misdemeanor arrest unless the offense occurred in their presence. While CVC § 40300.5 allows an exception for traffic accidents, the arresting officer did not witness a collision and lacked competent, admissible physical evidence or a completed collision report at the time of entry.
Because a lawful arrest is a mandatory prerequisite for any refusal suspension under CVC § 13353 (Mercer v. DMV [1991]), the unlawful entry rendered the entire administrative suspension invalid.
2. Contradictions and Omissions on Official DMV Documents
A critical element in APS defense is holding law enforcement to the strict evidentiary standards required by sworn statements. Matthew Ruff highlighted fatal defects in the officer’s DS-367 statement:
On Page 2 of Form DS-367, the officer marked “NO” next to “Will you take a Blood Test?”, but left the field for “Will you take a Breath Test?” completely blank.
Under CVC § 23612, drivers have a statutory right to choose between a breath or blood test. Refusing one specific test (blood) while the officer fails to record or offer the alternative (breath) does not legally constitute a refusal under CVC § 13353.
3. Unsubstantiated Claim of Equipment Unavailability
The arresting deputy marked Box 5(a) on Form DS-367 claiming the breath test was “unavailable,” yet failed to provide any written articulation or explanation in the designated fields.
Transporting a driver to a Sheriff’s Station equipped with standard breath testing apparatus while improperly restricting their statutory choice—without documenting why the device was out of order or inaccessible—rendered the chemical test admonition legally defective.
The Verdict: Suspension Set Aside in Full
On September 17, 2026, following a formal Driver Safety Hearing, the California Department of Motor Vehicles Legal Affairs Division issued an official Order of Set Aside, see below:
DUI Attorney Matthew Ruff Wins Refusal Case
The DMV Hearing Officer ruled:
Determination: Unlawful arrest – Set Aside.
Result: The 1-year hard license suspension was completely rescinded, full driving privileges were restored, and [Client] avoided a catastrophic disruption to his personal and professional life.
Key Takeaways for Drivers Facing DUI Charges in California
1. Refusal Allegations Are Fightable: An allegation of a refusal is not an automatic guilty verdict at the DMV. Officers frequently make procedural and constitutional errors during arrests and paperwork execution.
2. Strict Deadlines Apply: Drivers have only 10 calendar days from the date of arrest to request a DMV Driver Safety Hearing and stay the suspension.

When facing misdemeanor charges in Southern California, having an experienced criminal defense lawyer can make all the difference. Under California Penal Code § 381b, it is illegal to possess nitrous oxide with the intent to inhale it for the purpose of causing intoxication, euphoria, or altered mental states. However, an arrest citation is only the beginning of a case—not the final verdict.
Matthew J. Ruff, DUI Attorney
Top-tier California defense attorney Matthew Ruff recently demonstrated how strategic legal defense and meticulous analysis of law enforcement procedures can result in a complete dismissal of charges in Los Angeles Superior Court.
The Incident and Citation
The case stemmed from a traffic stop by the Los Angeles County Sheriff’s Department in 2026. Sheriff’s deputies issued a Notice to Appear citation alleging violations of Penal Code 381b (possession of nitrous oxide for inhalation purposes).
Key details from the citation included:
Issuing Agency: Los Angeles County Sheriff’s Department
While law enforcement officers frequently issue citations based on suspicion or the mere presence of canisters, proving the specific legal elements required under PC 381b in a court of law is a far higher standard.
The Defense Strategy: How Attorney Matthew Ruff Won a Dismissal
Upon taking the case, attorney Matthew Ruff reviewed the citation, police reports, and surrounding circumstances to target key vulnerabilities in the prosecution’s case.
Challenging Specific Intent: Penal Code 381b requires the prosecution to prove beyond a reasonable doubt that the driver possessed nitrous oxide specifically for the purpose of inhalation to alter mental status. Simple possession or transport is not inherently illegal without direct proof of intent. Furthermore, there was no evidence the accused was driving under the influence of nitrous oxide. (VC23152e)
Analyzing Search and Seizure Protocols: Attorney Ruff examined whether deputies had sufficient reasonable suspicion or probable cause to perform the initial stop and subsequent vehicle search.
Evidentiary Gaps: Mr. Ruff highlighted the lack of direct physical evidence (such as balloons, immediate admissions, or active inhalation) linking the client to illegal use at the time of the stop.
By filing pre-trial motions and negotiating aggressively with the prosecutor, Attorney Ruff demonstrated that the state lacked the necessary evidence to secure a conviction at trial. Faced with these evidentiary weaknesses, the prosecution agreed to drop the matter, resulting in a full dismissal of all charges in Los Angeles Superior Court.
Proving a person is under the influence of nitrous oxide is difficult
Proving that a driver or individual was operating under the influence of nitrous oxide presents unique hurdles for law enforcement and prosecutors. Unlike alcohol or standard narcotics, nitrous oxide (N_2O) interacts with the human body in a way that creates a evidentiary gap between physical observation and forensic confirmation.
1. Ultra-Short Half-Life and Rapid Elimination
The primary barrier to proving impairment is the compound’s pharmacokinetics. Nitrous oxide is an inhaled gas that diffuses rapidly out of the bloodstream through the lungs. Within minutes—often before an officer can initiate a traffic stop, let alone secure a warrant for a blood draw—the chemical has already been exhaled and cleared from the body. Traditional blood or urine samples collected hours later routinely return negative or inconclusive results.
2. Absence of Standardized Chemical Testing
Standard breathalyzers are calibrated exclusively to measure ethanol (alcohol) molecules. They cannot detect inhalants. Furthermore, standard hospital or crime lab toxicology panels do not automatically screen for compressed gases. Detecting nitrous oxide in blood requires specialized gas chromatography methods applied to sealed headspace vials, which are rarely utilized in routine investigations unless law enforcement specifically suspects gas inhalation immediately at the scene.
3. Rapidly Dissipating Physical Symptoms
While acute intoxication produces dizziness, spatial disorientation, euphoria, and slowed reflexes, these effects peak quickly and usually dissipate within 5 to 15 minutes of cessation. By the time a Drug Recognition Expert (DRE) arrives to conduct a standardized evaluation, the acute physical symptoms may have vanished entirely, leaving behind little to no measurable physical impairment during field sobriety tests.
4. Overlap with Other Medical Conditions
The residual symptoms of nitrous oxide exposure—such as loss of balance, slurred speech, or confusion—are non-specific. Without toxicological confirmation, defense arguments can readily attribute these signs to fatigue, neurological events, medical emergencies, or simple anxiety, making it difficult for the state to meet the high burden of proof beyond a reasonable doubt.
Why Results Matter
A conviction for PC 381b creates a criminal record that can affect employment, professional licensing, and background checks. By taking a proactive approach, Matthew Ruff protected his client’s clean record, avoided trial, and spared them from criminal penalties.
If you or a loved one are facing misdemeanor or drug-related charges in Los Angeles County, having a dedicated defense lawyer who fights for a dismissal from day one is critical. If you or a loved one has been arrested or charged with a crime involving nitrous oxide, whether it be possession or driving under the influence of nitrous oxide, Top DUID Attorney Matthew Ruff can help.
Seeing blue lights and a maze of cones ahead on a Friday night instantly spikes anyone’s heart rate. Sobriety roadblocks have become increasingly common across Southern California—especially throughout the South Bay in cities like Hermosa Beach, Torrance, Manhattan Beach, and Redondo Beach.
DUI Checkpoint
While law enforcement frames these stops as public safety measures, the reality is that DUI checkpoints rely on broad police authority that can easily cross constitutional boundaries. Knowing your rights and how to navigate a roadblock calmly can protect you from an unlawful arrest.
Here is crucial guidance on what to do—and what not to do—when approaching a DUI checkpoint.
1. Turning Away Isn’t Illegal, But Mind the Rules
A common misconception is that avoiding a checkpoint is an automatic crime. Legally, making a lawful turn onto a public street to avoid entering a roadblock is entirely within your rights.
However, police actively monitor surrounding perimeter streets looking for a reason to pull you over.
Do: Make a standard, legal turn or lane change using your turn signal if you can safely bypass the stop.
Don’t: Execute an illegal U-turn, make an unsafe lane change, or commit traffic violations. Law enforcement will immediately use any minor traffic infraction as a pretext to stop and detain you.
2. Hand Over Documents Calmly
When it is your turn to stop, officers will ask for your driver’s license, registration, and proof of insurance.
Have your documents accessible to avoid fumbling in the glove box, which officers often mistake for impaired motor skills.
Roll your window down enough to comfortably hand over your documents. Keep your interactions brief, polite, and calm.
3. Know Your Right to Remain Silent
Officers routinely ask probing questions designed to get you to admit to drinking (e.g., “Where are you coming from tonight?” or “Have you had anything to drink?”).
You are legally required to identify yourself and produce vehicle documentation, but you are not required to answer incriminating questions.
Politely state: “I prefer to keep my answers brief, and I would like to exercise my right to remain silent until I speak with an attorney.”
Avoid volunteering extra information about where you were or what you consumed.
4. Voluntary vs. Mandatory Testing
Understanding the difference between optional field tests and mandatory post-arrest tests is critical:
Field Sobriety Tests (FSTs): Physical balance coordination tests and preliminary roadside breathalyzers (PAS tests) are generally voluntary for drivers over 21 who are not on DUI probation. You have the right to politely decline roadside FSTs without penalty.
Post-Arrest Chemical Tests: If an officer places you under formal arrest, California’s Implied Consent Law requires you to submit to an official breath or blood test. Refusing a post-arrest test carries severe administrative penalties, including automatic license suspension.
What to Do If You Are Arrested
If an officer places you under arrest, do not argue, resist, or try to convince them otherwise on the roadside. Remain silent, request to speak with legal counsel, and comply with official procedures is the advice of most Top DUI Checkpoint Attorneys
Checkpoints must strictly comply with constitutional standards established in California cases like Ingersoll v. Palmer. If police fail to follow mandatory procedures—such as failing to maintain continuous observation for breath tests, setting up checkpoints without proper neutral formulas, or stopping drivers without reasonable suspicion—the entire arrest and evidence collected can be challenged in court.
