Defenses to Crimes in Arizona

Facing a criminal charge can feel overwhelming, but it doesn’t decide your future. At the Law Office of James E. Novak, we start by reminding you that the State must prove every element beyond a reasonable doubt. Our job is to test that proof, tell your side clearly, and use the law to protect your record and your future. Below, our Phoenix criminal defense attorney outlines common defenses and how early action can change the outcome of your case.

What a Criminal Defense Actually Does

A criminal defense can do one of two things. First, it can challenge the State’s evidence by showing that police made mistakes, witnesses are unreliable, or the proof is too weak to meet the high standard required. Second, it can justify or excuse the conduct—showing the law allows what happened under the circumstances. Either path can lead to a dismissal, a reduction in charges, or a not-guilty verdict.

A good defense starts with facts. That means collecting body-camera footage, saving texts and social media messages, identifying witnesses, and getting medical or phone records before they disappear. Small details often decide cases.

Common Justification and Excuse Defenses

These defenses admit some facts but argue that the law excuses or permits the conduct. When supported by evidence, they can defeat criminal liability.

• Self-defense and defense of others: You may use reasonable force if you reasonably believe it is immediately necessary to prevent unlawful force. The level of force must match the threat; deadly force requires a higher justification.
• Defense of property or home: Limited force may be used to stop theft or unlawful entry when your response is proportionate to the situation.
• Duress: If someone forced you to commit an offense by threatening immediate serious harm, the law may excuse your actions.
• Necessity: In rare emergencies, breaking the law to avoid a greater harm can be justified—for example, driving without valid privileges to get someone to urgent medical care when no safe alternative exists.
• Entrapment: When the idea for the crime came from law enforcement and you were not already willing to commit it, the case may be barred.

These defenses are highly fact-specific. Your state of mind, what you perceived, how quickly events unfolded, and whether you had safer options all matter. Photos, videos, 911 recordings, and medical records can make the difference.

Evidence and Procedure Defenses

You can also win by excluding or undermining the State’s proof. Arizona judges must suppress evidence gathered in violation of your constitutional rights, and weak or unreliable evidence should not support a conviction.

• Illegal stops, searches, and seizures: If police lacked reasonable suspicion or probable cause, searched beyond a warrant or consent, or extended a stop without justification, key evidence can be thrown out.
• Miranda and interrogation violations: Statements made during custodial questioning without proper warnings—or after you asked for a lawyer or to remain silent—may be excluded.
• Faulty scientific testing: Breath machines, blood draws, drug testing, and other forensic methods must follow strict protocols. Calibration errors, chain-of-custody gaps, contamination, and unqualified lab work can render results unreliable.
• Mistaken identity and unreliable witnesses: Stress, poor lighting, cross-racial identifications, and suggestive lineups cause errors. Surveillance video, phone GPS data, and alibi witnesses can correct the record.
• Insufficient evidence: If the State cannot prove every element—such as “intent” in a theft case—the court should reduce or dismiss the charge.

Charge-Specific Strategies

Because each offense has unique elements, defense strategies must fit the charge and the facts.

• DUI: Challenge the legality of the stop, field-sobriety procedures, the timing and handling of breath or blood tests, and medical conditions (like acid reflux or diabetes) that can affect readings.
• Assault and domestic violence: Focus on self-defense, defense of others, mutual combat, or lack of intent. Independent witnesses, injury photos, prior aggression by the accuser, and messages sent before or after the incident can be crucial.
• Theft and fraud: Show lack of intent to permanently deprive, a claim of right to the property, billing mistakes, or that there was no material misrepresentation.
• Drug offenses: Contest knowledge and control of the substance, challenge the search, and scrutinize lab testing. Quantity, packaging, and the absence of sales tools can defeat “intent to sell.”
• Sex offenses: Consent, inconsistent accounts, digital timelines, and expert testimony on memory and suggestibility often drive outcomes.

How a Defense Lawyer Builds Your Case

Time is critical. Early work can uncover helpful footage, keep witnesses cooperative, and prevent the State from controlling the narrative. A focused defense typically includes:

• Reviewing body-camera videos, reports, and 911 audio
• Preserving surveillance video and digital evidence
• Interviewing witnesses before memories fade
• Retaining experts (forensics, toxicology, use-of-force, accident reconstruction) when needed
• Filing targeted motions to suppress evidence or dismiss charges
• Negotiating from a position of strength while preparing for trial

You should also expect clear communication about your options. Sometimes diversion or a plea to a lesser charge protects your record. Other times, taking the case to a hearing or trial is the best move. The right choice depends on the facts, the law, and your goals.

What You Can Do Right Now

Do not discuss your case with anyone but your attorney. Do not post about it online. Save potential evidence (photos, videos, messages) and write down what happened while it is fresh. Bring all paperwork to your consultation, including release forms so your lawyer can obtain records fast.
