What Is an Accusatory Instrument in New York?

An accusatory instrument in New York is the formal written document that starts a criminal case against you. Nothing happens in criminal court until one is filed, and the specific type filed, whether an information, a misdemeanor complaint, a felony complaint, an indictment, or a simplified information, controls what the prosecution has to prove at the outset, whether a grand jury has to get involved, and how quickly the case must move.¹ The document tells you what you’re accused of doing, when and where you allegedly did it, and which statute the prosecution says you broke.

The type of instrument also sets the legal standards the prosecution has to meet. If the factual allegations don’t support every element of the charged offense, the case can be dismissed before it reaches a jury. That gatekeeping function is why challenges to accusatory instruments are among the most common and effective pretrial motions in New York criminal practice.

The Types of Accusatory Instruments

New York uses different instruments for different levels of offense. Figuring out which one you’re facing is the first step in understanding where your case is headed.

Information

An information is the standard instrument for prosecuting misdemeanors and violations in local criminal court. It’s a verified written accusation, and it carries the highest evidentiary bar among local court instruments: the factual allegations must be based on non-hearsay evidence and, if accepted as true, must establish every element of the charged offense.² Secondhand accounts or anonymous tips alone are not enough. The person signing the information, or a witness filing a supporting deposition alongside it, has to provide firsthand factual allegations covering each element of the crime. An information can start the case and carry it through trial.

Misdemeanor Complaint

A misdemeanor complaint looks similar to an information but carries a lower burden. Factual allegations can be based on information and belief rather than personal knowledge, and the standard is reasonable cause to believe the defendant committed the offense rather than non-hearsay proof of every element.² That makes it quick to file, which is why it’s often the first document drafted after an arrest. The tradeoff is that a misdemeanor complaint alone cannot sustain a prosecution through trial. It must eventually be replaced by an information, and if the prosecution can’t make that conversion in time, the case runs into trouble.

Felony Complaint

A felony complaint is the initial charging document for offenses that can result in more than one year of imprisonment. Like a misdemeanor complaint, its factual allegations need only establish reasonable cause, based either on personal knowledge or information and belief.³ It’s a preliminary step. At arraignment, the court informs the defendant that the primary purpose of the proceeding is to determine whether the case should go to a grand jury.⁴ A felony complaint cannot serve as the trial instrument on its own.

Indictment

An indictment is a written accusation issued by a grand jury and filed with a superior court. It’s the instrument that formally charges one or more defendants with at least one felony and serves as the basis for prosecution at trial.⁵ Unlike complaints and informations, which are prepared by police or civilian complainants, an indictment comes from the grand jury after it reviews evidence presented by the district attorney. It must contain a plain and concise factual statement supporting every element of the charged offense, identify the county where the offense occurred, and specify the date or time period. For armed felonies, it must also identify the specific weapon.

Superior Court Information

In some felony cases, you can skip the grand jury by waiving indictment and agreeing to be prosecuted on a superior court information filed by the district attorney. This option is available only when the local criminal court has already held the defendant for grand jury action, the district attorney consents, and the charge is not a class A felony punishable by life imprisonment.⁶ Defendants sometimes choose this route as part of a plea agreement because it moves faster.

Simplified Information

Simplified informations are the streamlined instruments used for traffic infractions and traffic-related misdemeanors. They’re prescribed by the Commissioner of Motor Vehicles, or by the relevant commissioner for parks and environmental offenses, and they deliberately omit the detailed factual allegations other instruments require.⁷ If you’ve ever received a traffic ticket, you’ve held one. The New York Court of Appeals has described them as “streamlined instrument[s] designed for the expeditious processing of traffic infractions.”⁸

Despite the abbreviated format, you have the right to demand a supporting deposition from the officer who issued the ticket. The request must be made before you enter a guilty plea and before trial begins, and no later than 30 days after the date you were told to appear.⁷ Once requested, the court orders the officer to serve the deposition within 30 days or at least five days before trial, whichever comes first. If the officer doesn’t comply, the simplified information becomes insufficient on its face and can be dismissed.² This is one of the most practically useful rights defendants have in traffic cases, and it’s frequently overlooked.

Prosecutor’s Information

A prosecutor’s information is filed by the district attorney rather than a civilian complainant. It can arise in two ways: the district attorney may file one at a grand jury’s direction when the grand jury decides a case warrants misdemeanor rather than felony charges, or the district attorney may file one independently to supersede an existing information, as long as the original factual allegations support the new charges.⁹ It follows the same sufficiency standards as a regular information.

What Makes an Instrument Legally Sufficient

The distinction between what makes a complaint sufficient and what makes an information sufficient is one of the most consequential details in New York criminal procedure, and it’s where a lot of cases get tripped up.

An information is sufficient on its face only when three conditions are met: it substantially conforms to the form requirements of CPL 100.15, its factual allegations provide reasonable cause to believe the defendant committed the offense, and non-hearsay allegations establish every element of the charged offense if accepted as true.² The third requirement is the one prosecutors stumble on most often. Hearsay can fill in background, but the core facts proving each element must come from someone with firsthand knowledge.

Misdemeanor complaints and felony complaints face a lower bar. They need only conform to the form requirements and provide reasonable cause to believe the defendant committed the offense.² There’s no non-hearsay requirement for complaints. A police officer can file a felony complaint based partly on what witnesses said at the scene, but those witnesses would need to provide their own depositions before the case could proceed on an information.

Facial sufficiency is a jurisdictional requirement that cannot be waived. If the instrument doesn’t meet its applicable standard, the court lacks the power to proceed, and that defect can be raised for the first time on appeal even if nobody objected at trial.¹⁰ The Court of Appeals confirmed in People v. Casey that the factual portion of an information must provide reasonable cause through non-hearsay allegations establishing every element of the offense.¹¹

Supporting Depositions

A supporting deposition is a separate written statement filed alongside or after an accusatory instrument. It’s prepared by someone other than the original complainant and contains additional factual allegations that supplement the charges.¹² Supporting depositions matter most in two situations: when an information needs non-hearsay factual allegations from a witness other than the complainant to cover all elements of the offense, and when a defendant charged by simplified information demands one.

Deadlines That Protect You

Two sets of deadlines put real pressure on the prosecution once charges are filed.

The Five-Day Rule for Misdemeanor Complaints

Because a misdemeanor complaint doesn’t meet the non-hearsay standard required for trial, the prosecution must replace it with an information. Conversion usually involves securing supporting depositions from witnesses who can provide firsthand factual allegations covering every element of the offense.

If you’re held in custody on a misdemeanor complaint and no information is filed within five days (not counting Sundays), the court must release you on your own recognizance, unless you’ve waived prosecution by information or the court finds good cause for the delay.¹³ Good cause means a compelling fact or circumstance that actually prevented the replacement, not just prosecutorial backlog. Defense attorneys watch this clock closely.

Speedy Trial

CPL 30.30 imposes strict deadlines on prosecutorial readiness for trial, measured from the filing of the first accusatory instrument. The prosecution must be ready within:

Six months for cases involving at least one felony charge
90 days for cases where the most serious charge is a misdemeanor punishable by more than three months of imprisonment, and no felony is charged
60 days for cases where the most serious charge is a misdemeanor punishable by no more than three months of imprisonment

The statute frames the cutoffs around the maximum imprisonment for the charged offense rather than using class labels.¹⁴ In practice, the 90-day window typically applies to class A misdemeanors (up to one year in jail), and the 60-day window to class B misdemeanors (up to three months). Missing these deadlines gives you grounds to move for dismissal, and courts grant those motions. Speedy trial violations are among the most common reasons misdemeanor cases get thrown out.

Challenging an Accusatory Instrument

After arraignment, you can move to dismiss any local criminal court accusatory instrument on several grounds. The most frequently invoked is that the instrument is defective, meaning it doesn’t meet the applicable sufficiency standard under CPL 100.40.¹⁵ Other grounds include:

Immunity from prosecution for the charged offense
Double jeopardy from a prior prosecution for the same conduct
Statute of limitations
Speedy trial violation under CPL 30.30
Interest of justice, based on the totality of circumstances, even if the instrument is technically sufficient

An instrument is defective when it fails the facial sufficiency requirements, when it shows the court lacks jurisdiction over the charged offense, or when the underlying statute is unconstitutional.¹⁶ Not every defect leads to automatic dismissal. If the problem can be fixed by amendment, the court must allow the prosecution to amend rather than dismiss outright. Only defects that go to the core of the instrument’s legal validity result in dismissal.

One procedural trap: CPL 170.30 expects you to raise every available ground for dismissal in a single motion. If you hold back a ground you could have raised, the court can summarily deny a later motion based on it, though judges retain discretion to hear it anyway for good cause.¹⁵ Raise everything the first time.

When the Prosecution Changes the Charges

Accusatory instruments are not set in stone. Before you enter a guilty plea or trial begins, the prosecution can file a new information or prosecutor’s information that supersedes the original. When the new instrument charges the same offense, the corresponding count in the original is dismissed. If the original also charged offenses not included in the replacement, those counts survive and continue alongside the new filing.⁹

Supersession is the practical safety valve for prosecutors who discover factual errors or want to adjust charges based on new evidence. Your key protection is timing: once a guilty plea is entered or trial starts, the prosecution can no longer swap out the charging document. Until that point, expect the charges to potentially shift as the prosecution refines its case.
