What Constitutes a Criminal Offense under New York Law

A criminal offense is an act or omission that the state prohibits and punishes by statute. To secure a conviction, the prosecution must prove every element of the charge beyond a reasonable doubt. Most offenses require two core elements:

• Actus reus: a voluntary act, or an unlawful omission where the law requires action
• Mens rea: a culpable mental state at the time the act occurred

Both must be proven. The facts of how an event unfolded carry as much weight as the event itself, which is why investigation is central to any defense from the start.

Most criminal matters in Brooklyn are prosecuted under New York State law in state court. A charge shifts to federal when it involves a federal statute, crosses state lines, or implicates a federal agency. Drug trafficking networks, securities fraud, and certain firearms violations frequently land in federal court, where sentencing guidelines are stricter and mandatory minimums more common. Our attorneys handle cases in both forums.

Felonies are the most serious category. New York uses a lettered system from Class A down to Class E, with each class carrying a different statutory maximum.

For non-citizens, a New York felony conviction may also qualify as an aggravated felony under federal immigration law, triggering mandatory removal proceedings regardless of how long the person has lived in the United States.

Misdemeanors are less serious than felonies but still produce a criminal record on conviction.

• Class A misdemeanor: up to 364 days in jail and a fine of up to $1,000. Common charges at this level include assault in the third degree and petit larceny.
• Class B misdemeanor: up to 90 days in jail. Harassment in the second degree is a frequent charge at this tier.

A violation carries a maximum of 15 days in jail and is not technically a crime under New York law, meaning a violation disposition does not produce a criminal record. Disorderly conduct under Penal Law § 240.20 is the most commonly charged violation and often serves as a negotiated resolution to reduce a misdemeanor charge. Traffic infractions are non-criminal offenses under the Vehicle and Traffic Law and do not appear on criminal background checks, but they are not 'civil matters' in the same sense as private lawsuits; they are adjudicated in traffic court and can result in fines, license suspension, or points on a driving record.

New York Penal Law § 15.05 sets out four culpable mental states. Acting intentionally means the person's conscious objective was to cause the result. Acting knowingly means the person was aware the conduct was of the criminal nature charged. Recklessly means the person was aware of a substantial and unjustifiable risk and chose to disregard it. Criminal negligence means the person should have been aware of that risk but was not.

The mental state the prosecution charges determines the severity of the offense and how a defense is built.

Prosecutors rarely have direct evidence of what a defendant was thinking. They build the case from circumstantial evidence: statements made before or after the incident, the defendant's actions at the scene, surveillance footage, text messages, and witness accounts. Challenging that chain of inferences is often central to a strong defense.

Assault charges range from third-degree misdemeanors to first-degree Class C felonies, depending on the severity of injury and whether a weapon was involved. Burglary and larceny charges frequently turn on intent at the time of entry and the circumstances of the alleged taking, issues where early evidence review can shift the result.

Drug possession and sale under Article 220 of the Penal Law remain among the most frequently prosecuted charges in Brooklyn. The type of substance and its weight determine the offense tier, which ranges from a Class A misdemeanor to a Class A-I felony. Drug sentencing in New York has changed significantly over the past decade, and mitigation evidence now carries more weight at sentencing than it once did. White-collar matters including fraud, embezzlement, and identity theft increasingly reach state court alongside, or instead of, federal prosecution.

Sentencing reflects the classification of the offense, the defendant's prior record, and any applicable mandatory minimum provisions. A judge may impose a custodial sentence, a period of probation or conditional discharge, a fine, restitution to the victim, or some combination. Persistent felony offender and violent felony offender statutes set sentencing floors for defendants with qualifying prior convictions under New York Penal Law §§ 70.10 and 70.02. Under § 70.10, a defendant with two or more prior felony convictions who is convicted of a new felony may be sentenced to an indeterminate life term if the court finds that extended incarceration and lifetime supervision will best serve the public interest. Under § 70.08, a defendant with two or more prior violent felony convictions who is convicted of a new violent felony must receive a life sentence without parole.

A conviction creates a permanent public record. Employers, landlords, and professional licensing boards run background checks, and a conviction will appear. Housing applications in New York City can be denied based on criminal history under the standards of New York Correction Law Article 23-A. New York's Clean Slate Act (CPL § 160.57), which took effect on November 16, 2024, provides for automatic sealing of most misdemeanor convictions after 3 years and most felony convictions after 8 years, provided the individual has no pending charges and is not on probation or parole. However, Class A felonies (except certain drug offenses), sex crimes, and sexually violent offenses are expressly excluded from automatic sealing. Sealed records can still surface in certain contexts, such as fingerprint-based background checks for work with children, the elderly, or vulnerable adults, and do not erase the underlying conviction. For those exploring record relief, criminal record expungement and sealing options depend heavily on the nature of the original offense and the time elapsed since conviction.

Every person charged with a criminal offense has the right to counsel under the Sixth Amendment. If you cannot afford an attorney, one will be appointed. The due process protections of the Fourteenth Amendment require the state to follow proper procedures from the initial stop through arraignment and sentencing. Violations of those procedures can lead to suppressed evidence or dismissed charges.

The period after an arrest is often the most consequential stage of a case. Statements made before counsel is present can be used at trial. Evidence can disappear, witnesses become harder to reach, and decisions about the specific charges often solidify early in the process. Retaining counsel as soon as possible preserves options that close as the case advances.

Our attorneys examine the legality of the stop or arrest, whether law enforcement obtained evidence lawfully, and whether the prosecution's theory of intent holds under scrutiny. That review shapes the defense strategy from the beginning and identifies points of vulnerability in the state's case.

Not every case should go to trial, and not every plea agreement is a good result. Our firm assesses whether a negotiated resolution serves a client's long-term interests or whether contesting the charge is the stronger path. When a case goes to trial, our attorneys challenge the prosecution's evidence from jury selection through closing argument.
