Obstruction Lawyer for New Brunswick and Middlesex County Courts

Reviewed by William A. Proetta, Esq. · Updated October 2026

Obstructing the administration of law, N.J.S.A. 2C:29-1, is usually a disorderly persons offense with a maximum of 6 months in jail and a $1,000 fine. It becomes a 4th-degree crime, with up to 18 months and a $10,000 fine, when the interference obstructs the detection or investigation of a crime or the prosecution of someone for a crime.

A disorderly persons obstruction count stays in the municipal court where the incident happened, such as Edison Municipal Court (100 Municipal Boulevard), Woodbridge Municipal Court (1 Main Street) or Piscataway Municipal Court (555 Sidney Road). The 4th-degree version is indictable and is screened by the Middlesex County Prosecutor’s Office for the Superior Court in New Brunswick. We defend both from our Edison office, backed by more than 15 years of criminal trial work.

What the Prosecution Has to Show

The statute is broader than most people expect, but it has firm limits. The State must prove two things.

1. A purpose to obstruct. The person must have purposely obstructed, impaired or perverted the administration of law or another governmental function, or prevented or tried to prevent a public servant from lawfully performing an official function. Carelessness, misunderstanding or slowness is not enough.

2. One of the listed means. The interference has to come through:

• flight,
• intimidation,
• force or violence,
• physical interference or an obstacle, or
• an independently unlawful act.

The second element is where many charges fail. The statute expressly excludes a failure to perform a legal duty that is not an official one, and other ways of avoiding compliance that involve no affirmative interference with a governmental function. In plain terms, passive non-cooperation is not obstruction. Declining to answer questions, refusing consent to a search, or asking whether you are free to leave is not an affirmative act of interference. Our guide to your rights during police questioning explains what you can decline.

What does qualify, on typical police reports: running from a stop, standing in a doorway to block officers, swallowing or throwing away evidence, grabbing a phone an officer is trying to secure, or refusing to step out of a car combined with physical bracing.

Flight from a stop is obstruction even if the stop was bad

The New Jersey Supreme Court settled this point. In State v. Crawley, 187 N.J. 440 (2006), the Court held that a person ordered to stop must obey and “may not take flight without violating N.J.S.A. 2C:29-1,” even if a court later finds the stop unconstitutional, so long as the officers acted in objective good faith. State v. Williams, 192 N.J. 1 (2007), added that “a person has no constitutional right to flee from an investigatory stop.” The challenge to the stop belongs in a courtroom, not on the sidewalk.

Obstruction by Grade

The line between the tiers is not whether the underlying matter was serious in a general sense; it is whether the interference got in the way of a criminal investigation or prosecution. Blocking an officer at a noise complaint or a traffic stop for a Title 39 violation is generally disorderly persons. Flushing drugs while detectives execute a search warrant points to 4th degree.

Penalties and Collateral Effects

• No NERA, no Graves Act, no registration. Neither tier is 1st or 2nd degree, and obstruction is not a weapons or sex offense.
• Presumption against jail. A first offender convicted of the 4th-degree crime has a presumption of non-imprisonment under N.J.S.A. 2C:44-1(e).
• Expungement. Obstruction is not on the 2C:52-2(b) bar list. Waiting periods run five years for either grade, with early paths at three years (disorderly persons) or four years (indictable) on compelling circumstances.
• Professional and school records. Many licensing boards and background checks ask about any conviction, including disorderly persons. That is one reason we push for dismissal or diversion rather than a quick plea.
• Immigration. The effect of an obstruction plea on a non-citizen depends on the facts admitted and the other charges in the case. Have immigration counsel review the plea first.

How Obstruction Charges Move Through Middlesex County

Who files it. Obstruction is written by the arresting officer, almost always as an add-on: a person stopped on Route 1 in Edison who runs, a party in New Brunswick where someone blocks an apartment door, a search in Woodbridge where evidence goes missing. The disorderly persons version is normally charged on a summons, with a first appearance in that town’s municipal court. If the obstruction travels with an indictable count, police may use a complaint-warrant, and the person may be lodged at the Adult Correction Center on Apple Orchard Lane in North Brunswick pending a release decision.

The 4th-degree route. A 4th-degree count is forwarded to the MCPO at 25 Kirkpatrick Street. It may be presented to a grand jury in New Brunswick with the underlying charges, resolved by plea in the Superior Court at 56 Paterson Street, or remanded to the municipal court as a disorderly persons offense. A downgrade of an indictable charge in municipal court requires the county prosecutor’s consent on the record.

When the underlying charge falls apart. A common pattern: the drug or theft charge that prompted the stop is suppressed or dismissed, and the State keeps the obstruction count because Crawley insulates flight. We then focus on whether the officer acted in objective good faith, whether there was a clear order to stop, and whether the conduct was an affirmative act at all. Our motion to suppress page covers the companion litigation.

Students. Rutgers students charged after an off-campus party in New Brunswick may face a university conduct process at the same time. We coordinate what is said in each forum.

Diversion for Obstruction

For the disorderly persons charge, conditional dismissal under N.J.S.A. 2C:43-13.1 is frequently available to someone with no prior convictions and no earlier diversion, provided the case does not involve domestic violence. For the 4th-degree crime, a first offender can apply to PTI through the Middlesex Criminal Division before the first case disposition conference after arraignment; the PTI page has details.

Defenses We Raise

• No affirmative act. Silence, refusal of consent, slow compliance and verbal protest are not obstruction under the statute’s own exclusion.
• No purpose to obstruct. Walking away before any command was given, or leaving without knowing police wanted you, does not show a conscious aim to interfere.
• The officer was not lawfully performing an official function. The “prevents a public servant” clause requires a lawful function. Crawley limits this argument for flight from a stop, but it remains open where the officer’s conduct was not in objective good faith.
• Wrong grade. The 4th-degree tier requires interference with a criminal investigation or prosecution, not just with a motor vehicle stop or a municipal ordinance call.
• Video. Body-worn camera footage regularly shows a person complying, or a command that was never given.
