Westchester County Criminal Defense: What Happens after Arrest?

Practice Area:Criminal Law
Jurisdiction:New York

Westchester County criminal defense after an arrest involves court appearances, release decisions, and different procedures for misdemeanor and felony charges.

An appearance ticket may specify the required court date and location, while other arrest paperwork may not provide complete appearance details. After arraignment, the case may remain in local criminal court or proceed toward superior court, depending on the charge. Defendants also face custody deadlines, discovery requirements, and decisions about preserving relevant records.



1. The First Court Appearance after an Arrest


An arrest does not establish guilt. Under New York's Criminal Procedure Law (CPL), police may issue an appearance ticket or bring the arrested person before a judge. The charging documents identify the alleged offense and the court responsible for the initial proceedings.


Appearance Tickets and Return Dates

CPL § 150.20 generally requires appearance tickets for specified offenses, subject to statutory exclusions and exceptions. Under CPL § 150.40, the return date must ordinarily be as soon as possible and within 20 days of issuance.

A later date is permitted when the appropriate court's next scheduled session falls outside that period or the court approves qualifying pre-arraignment diversion. An appearance ticket requires attendance without necessarily keeping the defendant in custody beforehand.

What Happens at Arraignment?

CPL §§ 170.10 and 180.10 govern arraignments on misdemeanor and felony complaints. The court informs the defendant of the charges and addresses the right to an attorney, including appointed representation for eligible defendants who cannot afford one. Arraignment is not a trial; the court also addresses applicable plea procedures and pretrial release conditions.


2. Which Westchester County Court Handles the Case?


Westchester County has local criminal courts and a superior court with felony jurisdiction. City Courts and Town and Village Justice Courts conduct initial proceedings, while County Court generally handles felony trials. The first courthouse does not necessarily remain responsible for the entire prosecution.

A person arrested in Yonkers may initially appear in Yonkers City Court. An arrest within a town or village may instead lead to its Justice Court. Westchester County Court, located in White Plains, generally handles felony trials.

How Misdemeanor and Felony Cases Differ

Misdemeanor prosecutions generally remain in local criminal court. Under CPL § 170.65, a misdemeanor complaint ordinarily must be replaced by a legally sufficient information before trial unless the defendant validly waives that requirement.

Felony complaints follow CPL Article 180. A preliminary hearing examines whether sufficient evidence supports holding the defendant for further proceedings. An indictment or another authorized filing may move the prosecution into superior court.


3. Release Decisions and Custody Deadlines


New York courts determine pretrial release separately from criminal responsibility. CPL §§ 510.10 and 530.20 establish the framework for securing orders, including restrictions on monetary bail. The court considers the statutory criteria for reasonably assuring the defendant's return.


Release on Recognizance and Bail

Release on recognizance allows a defendant to remain outside custody based on a promise to appear. If additional restrictions are justified under the statute, the court considers authorized nonmonetary conditions.

Monetary bail or other securing orders are available only in qualifying circumstances. An arraignment and bail hearing addresses these pretrial decisions rather than the merits of the charge.

The 120-Hour and 144-Hour Rules

Under CPL § 180.80, a defendant held in custody pending disposition of a felony complaint may apply for release after more than 120 hours of qualifying custody, or 144 hours if a Saturday, Sunday, or legal holiday occurs during that custody. The period runs from the arrest or subsequent custody covered by the statute, not automatically from arraignment.

Release is subject to exceptions, including delays attributable to or accepted by the defendant, specified grand jury action, and good cause established by the prosecution. The expiration of the period does not automatically dismiss the charges.


4. How Do Charges and Evidence Affect the Next Stage?


The filed charge determines which elements prosecutors must establish and which procedures apply. Reviewing the accusatory instrument helps distinguish the alleged conduct from the statutory requirements. Early discovery and evidence challenges may affect how the prosecution proceeds.


Reviewing the Charges and Their Elements

Petit larceny under Penal Law § 155.25 requires proof of larceny as defined in § 155.05. The prosecution must establish the required wrongful taking or withholding of property and intent to deprive another person of it or appropriate it.

Assault charges involve different elements, including specified mental states and injury requirements. The precise statutory subsection determines what prosecutors must prove.

Discovery Deadlines and Suppression Issues

Under CPL § 245.10, prosecutors generally must provide initial discovery within 20 calendar days after arraignment when the defendant is in custody and 35 calendar days when the defendant is not. Certain traffic infractions and qualifying non-jailable municipal offenses are exempt from automatic discovery, although defendants may request disclosure by motion under the applicable statute.

Exceptionally voluminous materials or records unavailable despite diligent, good-faith efforts may justify a stay of up to 30 additional calendar days without a motion. The statute also permits applications for further extensions under CPL § 245.70(2). Protective-order procedures may restrict disclosure of specified information.

Discoverable materials may include police reports, witness statements, and recordings. Challenges to criminal evidence may involve unlawful searches, improperly obtained statements, or identification procedures. Courts decide suppression motions under the applicable constitutional and statutory standards.


5. Preserving Records While the Case Proceeds


Relevant records can disappear before discovery is complete. Surveillance footage may be overwritten, and digital records can become difficult to retrieve. Preserving original materials helps establish their source, timing, and authenticity.


Documents and Digital Records to Retain

The following materials may help establish what happened:

  • Appearance tickets, charging documents, and court notices.
  • Original photographs, recordings, and relevant messages.
  • Receipts and available location records establishing a timeline.
  • Names and contact details of potential witnesses.

Original files may contain metadata missing from screenshots or forwarded copies. Defendants should avoid deleting, editing, or altering potentially relevant materials.

Evidence Held by Third Parties

A business or another third party may possess relevant surveillance footage. Identifying the record holder and likely retention period helps determine whether preservation procedures are available.

Under CPL § 245.30(1), a party may request a court order preserving items subject to disclosure under § 245.20(1). Separate provisions govern specified access and discretionary discovery requests. An evidence preservation review may identify the applicable procedure without changing the underlying material.


6. Frequently Asked Questions


Can a Westchester County Arrest Lead to Federal Charges?

Yes, when the alleged conduct satisfies a federal criminal statute and the necessary jurisdictional requirements. Westchester County falls within the Southern District of New York, which has a federal courthouse in White Plains.

Federal prosecutions follow federal criminal law and the Federal Rules of Criminal Procedure. A local arrest alone does not establish federal jurisdiction or automatically result in federal charges.

What Happens if Someone Misses an Appearance Ticket Date?

Under CPL § 150.60, a court may issue a summons or arrest warrant when a defendant fails to appear after service of an appearance ticket and filing of the relevant accusatory instrument.

The court record determines whether additional process has been issued and what appearance is required next. Missing the date does not automatically establish guilt of the underlying offense.
