Most people assume that an arrest will lead them to a local courthouse down the road. But in New York City and on Long Island, a single criminal accusation can land you in federal court — a system that operates under entirely different rules, with different prosecutors, different judges, and dramatically different consequences.
The United States operates under a dual-court system: federal courts established by the U.S. Constitution and state courts created by each state’s own constitution and legislature. New York State has one of the most complex court structures in the country, with eleven different categories of trial courts. For residents of New York City, Nassau County, and Suffolk County, understanding which system applies to their case — and why it matters — can be the difference between years in a state prison and decades in a federal penitentiary.
Lebedin Kofman LLP handles cases in both the Southern District of New York (SDNY) and the Eastern District of New York (EDNY) — the two most active federal prosecution offices in America.
Two Separate Court Systems: A Structural Overview
The Federal Court System
The federal judiciary traces its authority directly to Article III, Section 1 of the U.S. Constitution, which vests the judicial power of the United States in one Supreme Court and in such inferior courts as Congress may establish. Today, the federal system operates as a three-tier hierarchy: 94 U.S. District Courts at the trial level, 13 U.S. Courts of Appeals at the intermediate appellate level, and the U.S. Supreme Court at the top.
Federal courts are courts of limited jurisdiction. They can only hear cases that fall within the scope of the Constitution and federal statutes — crimes that violate laws enacted by Congress, offenses committed on federal property, and disputes that cross state lines. Federal judges are nominated by the President, confirmed by the U.S. Senate, and serve lifetime appointments under Article III, insulating them from electoral politics.
The New York State Court System
New York’s court system has its own three-level structure: trial courts, the Appellate Division, and the Court of Appeals (which serves as the state’s highest court, not to be confused with the lower-level Supreme Court, which is New York’s principal trial court for felony cases).
For Long Island residents specifically, the court landscape includes:
Nassau County: The Nassau County District Court at 99 Main Street, Hempstead, handles misdemeanors and arraignments. The Nassau County Court at 262 Old Country Road, Mineola, handles felony cases. The Nassau County Supreme Court at 100 Supreme Court Drive, Mineola, serves as the principal trial court.
Suffolk County: The Suffolk County District Court operates six courthouses across western Suffolk towns. The Suffolk County Court at 210 Center Drive, Riverhead, handles felony matters.
Most New York State judges are elected by voters in partisan elections. Supreme Court justices serve 14-year terms and County Court judges serve 10-year terms. The seven judges on the Court of Appeals are appointed by the Governor with Senate confirmation to 14-year terms.
Which Federal Court Has Jurisdiction Over New York City and Long Island?
Two federal judicial districts serve the greater New York area, and understanding which one applies to your case is critical.
Eastern District of New York (EDNY)
The EDNY covers Nassau County, Suffolk County, Kings (Brooklyn), Queens, and Richmond (Staten Island), serving approximately 8 million people. The district operates out of two courthouses: the Theodore Roosevelt U.S. Courthouse at 225 Cadman Plaza East in Brooklyn, and the Central Islip Courthouse at 100 Federal Plaza, Central Islip, NY 11722, which serves Nassau and Suffolk County cases.
The Long Island Criminal Division, based in Central Islip, is responsible for investigating and prosecuting federal crimes impacting the approximately 2.8 million residents of Nassau and Suffolk Counties. Recent Long Island federal prosecutions include convictions of MS-13 gang members on racketeering charges, opioid diversion cases, public corruption matters, and securities fraud schemes. Appeals from the EDNY go to the U.S. Court of Appeals for the Second Circuit.
Southern District of New York (SDNY)
The SDNY covers Manhattan (New York County), the Bronx, Westchester, Rockland, Putnam, Orange, Dutchess, and Sullivan Counties. Often called the “Mother Court,” the SDNY is the oldest federal court in U.S. history, established in 1789, and is widely considered the most prestigious federal trial court in the nation. It handles high-profile securities fraud, white-collar crime, public corruption, terrorism, and major organized crime prosecutions. Appeals from the SDNY also go to the Second Circuit.
Jurisdiction: What Determines Whether a Case Goes Federal or State?
One of the most common questions people ask when facing criminal charges is whether their case will end up in state or federal court. The answer depends on the nature of the offense and who is investigating it.
When Federal Courts Have Jurisdiction
Federal courts have exclusive jurisdiction over crimes that cross state lines (such as interstate drug trafficking, kidnapping, and wire fraud), involve federal property or federal employees, violate federal statutes enacted by Congress, or relate to areas exclusively reserved to the federal government such as bankruptcy, immigration, counterfeiting, postal fraud, and firearms offenses under federal law.
Common federal crimes prosecuted in New York include drug trafficking (interstate or international), RICO/racketeering (18 U.S.C. §§ 1961–1968), bank robbery and bank fraud, mail fraud and wire fraud, federal firearms offenses, tax evasion and tax fraud, immigration offenses, identity theft, terrorism-related offenses, securities fraud and insider trading, child exploitation, and public corruption.
When State Courts Handle the Case
State courts handle the vast majority of criminal cases in New York, including assault, robbery, murder, theft, burglary, arson, drug possession below federal thresholds, DUI and traffic offenses, and domestic violence matters.
The Concurrent Jurisdiction Problem
Some crimes violate both state and federal law — bank robbery is a classic example. Both federal and state prosecutors may pursue separate actions, and the Fifth Amendment’s Double Jeopardy Clause does not bar dual prosecution under the separate sovereigns doctrine. In practice, federal prosecutors typically take over when crimes involve large-scale drug networks, organized crime enterprises, or offenses that cross county or state lines.
Key Procedural Differences Between Federal and New York State Courts
The procedural rules governing federal and state criminal cases differ in several important ways. These differences can significantly affect your defense strategy and the outcome of your case.
The Grand Jury Process
In the federal system, a grand jury indictment is mandatory for all federal felonies under the Fifth Amendment, unless the defendant waives this right. The defense cannot present evidence directly to a federal grand jury, and proceedings are strictly secret. The grand jury needs only to find probable cause to issue an indictment — and federal grand juries indict in the overwhelming majority of cases.
In New York State court, grand juries are also used, but the defense has a meaningful advantage: defense attorneys can submit affidavits, polygraph results, photographs, and other materials to persuade the grand jury not to indict. This pre-indictment window can be a critical strategic opportunity. An experienced criminal defense attorney may be able to present exculpatory evidence that prevents charges from ever being filed — an avenue that simply does not exist in the federal system.
Speedy Trial Rights
The timelines governing how quickly a case must go to trial differ significantly between the two systems.
In federal court, the Speedy Trial Act (18 U.S.C. § 3161) requires that trial commence within 70 days of the indictment or the defendant’s first appearance, whichever comes later. However, the 70-day clock contains numerous automatic exclusions for pretrial motions, competency evaluations, and “ends of justice” continuances, making it less protective in practice than it appears on paper.
In New York State court, the speedy trial rules under CPL § 30.30 give the prosecution a defined window to declare readiness for trial: six months for felonies, 90 days for Class A misdemeanors, 60 days for Class B misdemeanors, and 30 days for violations. Failure to meet these deadlines can result in dismissal of the case on the defendant’s motion.
Pretrial Detention and Bail
Federal and New York State courts take fundamentally different approaches to pretrial detention, and this distinction has enormous practical consequences for defendants.
The Federal System operates under the Bail Reform Act of 1984 (18 U.S.C. § 3142). A federal magistrate judge may order a defendant detained if the government proves by clear and convincing evidence that no conditions of release will reasonably assure community safety or the defendant’s appearance in court. The Act creates presumptions of detention for specific categories of offenses, including most federal drug crimes carrying a 10-year maximum, firearms offenses, terrorism charges, and crimes of violence. Federal detention hearings are adversarial and may involve live witness testimony. The government can seek detention based on both risk of flight and danger to the community.
New York State reformed its bail system in 2019 with amendments to CPL Article 510 that took effect on January 1, 2020. The reform eliminated money bail and pretrial detention for nearly all misdemeanors and nonviolent felonies. Judges are required to impose the least restrictive pretrial condition necessary to secure court attendance. For serious violent crimes, bail or detention remains available, but the judge’s analysis focuses on flight risk — not danger to the community, which is a critical distinction from federal law.
The bottom line: federal pretrial detention is significantly more common and harder to overcome than in New York State court, particularly for drug and gun-related charges.
Criminal Discovery
The rules governing what evidence the prosecution must share with the defense — and when — have undergone dramatic changes in New York State, creating a notable divergence from the federal system.
Federal criminal discovery is governed by Federal Rule of Criminal Procedure 16, which requires the government to disclose certain categories of materials. Witness statements are governed separately by the Jencks Act, and exculpatory evidence must be disclosed under the constitutional mandate of Brady v. Maryland.
New York State overhauled its discovery rules in 2020 with the passage of CPL Article 245, sometimes referred to as “Kalief’s Law.” Prior to this reform, New York had what criminal defense attorneys called the “blindfold law” — one of the most restrictive discovery regimes in the country. The new law requires automatic discovery, meaning the prosecution must turn over defined categories of evidence to the defense without a specific request and within specified timeframes. Exculpatory material must be disclosed automatically under CPL § 245.20.
Plea Bargaining and the Trial Penalty
The reality of modern criminal justice is that very few cases go to trial in either system. Approximately 98% of federal criminal convictions result from guilty pleas rather than trials, and the trial rate in New York State courts is similarly low.
What makes the federal system particularly daunting is the severity of the “trial penalty.” At the federal level, trial sentences are roughly three times higher than plea sentences for the same crime on average — and in some cases, eight to ten times higher. The American Bar Association has documented that this disparity is so coercive that innocent defendants sometimes plead guilty rather than risk the consequences of going to trial.
In the federal system, judges are prohibited from participating in plea negotiations, unlike some state systems where limited judicial involvement is permitted. Federal cooperating witnesses who provide “substantial assistance” under USSG § 5K1.1 can receive below-guideline sentences — a major strategic consideration that is unique to federal practice. Understanding how federal plea negotiations work is essential for anyone facing charges in the EDNY or SDNY.
Sentencing: Federal Sentencing Guidelines vs. New York Penal Law
The sentencing frameworks in federal and state court are structurally different, and the consequences can vary enormously for comparable offenses.
Federal Sentencing Guidelines
Federal sentencing is governed by the U.S. Sentencing Guidelines, published by the United States Sentencing Commission and updated annually. Since United States v. Booker (2005), the Guidelines are advisory rather than mandatory, but judges must calculate and consider the guideline range as a starting point before imposing sentence. The current framework uses a two-step process: first, the court calculates an advisory range based on the offense level and the defendant’s criminal history; second, the court considers the factors set forth in 18 U.S.C. § 3553(a) to determine the final sentence.
Federal mandatory minimum sentences are statutory floors that a judge generally cannot go below. Some examples that commonly arise in New York federal prosecutions include a 5-year minimum for offenses involving 28 grams of crack cocaine, 500 grams of powder cocaine, or 40 grams of fentanyl, and a 10-year minimum for 50 grams of crack, 5 kilograms of powder cocaine, or 400 grams of fentanyl. Under the Armed Career Criminal Act, defendants with three prior violent felony or serious drug convictions face a 15-year mandatory minimum.
A narrow “safety valve” provision may allow certain first-time, non-violent drug offenders to be sentenced below the mandatory minimum if they meet a specific five-part test. Federal sentences are served in Bureau of Prisons (BOP) facilities, which are often located far from the defendant’s home and family. For the latest changes to this framework, see our overview of federal sentencing reform.
New York State Sentencing Under the Penal Law
New York classifies felonies into five classes — A-I, A-II, B, C, D, and E — with further subdivisions into violent and non-violent categories under Penal Law § 55.05. The sentencing ranges for each class are as follows:
| NY Felony Class | Violent Felony Range | Non-Violent (No Prior Record) |
|---|---|---|
| A (Murder, major drug trafficking) | 20–25 years to life | 15–25 years |
| B | 5–25 years | 1–3 years minimum / 25 years maximum |
| C | 3.5–15 years | Probation to 15 years |
| D | 2–7 years | Probation to 7 years |
| E | 1.5–4 years | Probation to 4 years |
New York’s death penalty was effectively eliminated in 2004, when the Court of Appeals struck down the statute as unconstitutional in People v. LaValle — and the legislature has never restored it. The state’s Persistent Violent Felony Offender statute (Penal Law § 70.08) imposes a mandatory minimum indeterminate life sentence upon a third violent felony conviction, with minimums ranging from 6 to 25 years depending on the severity of the offense. New York sentences are served in DOCCS (Department of Corrections and Community Supervision) state facilities.
A key distinction: unlike the federal system’s rigid mandatory minimums tied to drug quantity, New York’s sentencing framework allows greater judicial discretion in many non-violent cases, including the possibility of probation for lower-level felonies.
How Judges Are Selected: Accountability vs. Independence
The way judges reach the bench differs fundamentally between the two systems, and these differences can have practical implications for criminal defense.
Federal judges — including district judges in the EDNY and SDNY — are nominated by the President and confirmed by the Senate to serve lifetime appointments. This insulates them from electoral politics and may make them more willing to issue rulings that are legally correct but politically unpopular, including orders suppressing evidence or dismissing charges.
Most New York State judges are elected in partisan elections. Supreme Court justices serve 14-year terms, County Court judges serve 10-year terms, and all face mandatory retirement at age 70. Judges who must stand for re-election may face different practical considerations than their life-tenured federal counterparts.
Federal vs. State Prosecutors and Law Enforcement
The prosecutors and investigative agencies involved in your case will differ depending on which court system has jurisdiction.
Federal Prosecution
Federal cases in the EDNY and SDNY are prosecuted by Assistant United States Attorneys (AUSAs) — career prosecutors who typically work within specialized units for narcotics, organized crime, public corruption, terrorism, securities fraud, and cybercrime. Federal investigations are conducted by agencies with enormous resources: the FBI, DEA, ATF, IRS Criminal Investigation, Homeland Security Investigations (HSI), the U.S. Secret Service, and the U.S. Postal Inspection Service. EDNY Long Island AUSAs have secured convictions of MS-13 leaders, opioid diversion physicians, and gang members operating across Nassau and Suffolk Counties.
New York State Prosecution
State criminal cases are prosecuted by the District Attorney’s Office of the county where the crime occurred — the Manhattan DA, Brooklyn DA, Nassau County DA, or Suffolk County DA. Investigations are conducted by the NYPD, Nassau County Police Department, Suffolk County Police Department, and the New York State Police.
Defense Representation
In the federal system, indigent defendants are represented by the Federal Defenders of New York, an independent nonprofit organization serving both the EDNY and SDNY. In the state system, the Legal Aid Society serves as New York City’s primary public defender, while Nassau and Suffolk Counties have their own legal aid organizations and assigned counsel programs. Defendants who retain private counsel should ensure their attorney has specific experience in whichever court system — federal or state — their case will be heard.
The Appeals Process: A Side-by-Side Comparison
Federal Appeals Path (EDNY/SDNY)
Federal criminal defendants convicted in the EDNY or SDNY follow a defined appellate path. The first appeal goes to the U.S. Court of Appeals for the Second Circuit, which is based at the Daniel Patrick Moynihan Federal Courthouse in Manhattan. Federal defendants have an automatic right to appeal to the circuit court after conviction. Under 28 U.S.C. § 1291, federal appeals are generally limited to final orders and judgments. From the Second Circuit, a defendant may petition the U.S. Supreme Court for discretionary certiorari review.
New York State Appeals Path
State criminal defendants in New York City, Nassau County, and Suffolk County appeal first to the Appellate Division, Second Department, which covers all cases from Kings, Queens, Richmond, Nassau, Suffolk, Westchester, Dutchess, Orange, Rockland, and Putnam Counties. From there, the next level of appeal is the New York Court of Appeals in Albany, the state’s highest court. If a federal constitutional question is presented, a further appeal to the U.S. Supreme Court is theoretically possible.
One important distinction: the New York Appellate Division may review questions “in the interest of justice” even if the issue was not properly preserved for appeal at the trial level — a more flexible standard than the Second Circuit’s strict preservation requirements.
Federal RICO and Organized Crime in New York
RICO — the Racketeer Influenced and Corrupt Organizations Act, codified at 18 U.S.C. §§ 1961–1968 — is exclusively a federal statute and represents one of the most powerful tools available to federal prosecutors in the EDNY and SDNY.
Federal prosecutors in both districts have used RICO aggressively against every major organized crime category in New York, from La Cosa Nostra to street gangs. The 1985 Mafia Commission Trial in the SDNY — prosecuted by then-U.S. Attorney Rudy Giuliani — charged the heads of New York’s Five Families under RICO, resulting in convictions that dismantled the traditional mob hierarchy. Each RICO count carries a maximum sentence of 20 years in federal prison, and when predicate acts include murder, the maximum is life imprisonment.
On Long Island, the EDNY has convicted hundreds of MS-13 members on RICO charges and has indicted MS-13 members for dozens of murders in the district. The EDNY and SDNY together handle a disproportionately large share of the nation’s terrorism prosecutions.
New York State has its own analogous statute — the Enterprise Corruption law (Penal Law § 460.20) — but it is used far less frequently than its federal counterpart.
When Does a State Crime Become a Federal Case in New York?
Understanding the red flags that can cause a state-level investigation to escalate into a federal criminal case is critical for anyone under investigation or facing charges in New York.
The most common triggers include multiple counties or states being involved, such as drug distribution networks or fraud schemes crossing geographic lines. If a federal agency like the FBI, DEA, ATF, or IRS initiates or joins the investigation, federal charges frequently follow. Financial crimes involving federally insured banks, federal tax obligations, or the use of interstate wires or the U.S. mail often fall under federal jurisdiction. Gang or organized crime allegations regularly prompt the EDNY and SDNY to convert local prosecutions into RICO cases. Federal firearms charges involving defendants with prior felony convictions carry mandatory minimums and are frequently prosecuted in federal court. Public corruption cases involving any federal program or official are almost always charged federally. And cybercrimes, child exploitation, and immigration offenses are nearly exclusive to the federal system.
The practical significance of this escalation cannot be overstated. Federal prosecutors have effectively unlimited investigative resources and typically achieve conviction rates exceeding 90% in both the EDNY and SDNY. Early intervention by a federal criminal defense attorney — before charges are formally filed — can be decisive in shaping the outcome.
Why Understanding the Difference Matters for Your Defense
Federal and New York State courts operate under fundamentally different rules, with different prosecutors, different judges, and dramatically different consequences. The Eastern District of New York — covering Nassau, Suffolk, Brooklyn, Queens, and Staten Island — and the Southern District of New York — covering Manhattan and the Bronx — are two of the most active and well-resourced federal prosecution offices in the United States.
Federal charges typically carry harsher sentences, mandatory minimums, and fewer opportunities for pretrial release than comparable state charges. The procedural rules governing grand jury rights, discovery obligations, and speedy trial deadlines are meaningfully different and require specialized expertise to navigate effectively.
If you are under federal investigation or have been charged with a federal crime in the EDNY or SDNY, the stakes demand experienced representation.

Frequently Asked Questions
What is the difference between the EDNY and SDNY?
The Eastern District of New York (EDNY) covers Brooklyn, Queens, Staten Island, Nassau County, and Suffolk County. The Southern District of New York (SDNY) covers Manhattan, the Bronx, and several counties north of the city including Westchester and Dutchess. Both districts have separate U.S. Attorney’s offices that independently investigate and prosecute federal crimes. If you live on Long Island or in Brooklyn, Queens, or Staten Island, your federal case will be handled by the EDNY, with courthouse locations in Brooklyn and Central Islip.
Can I be charged in both federal and state court for the same crime?
Yes. Under the separate sovereigns doctrine, the federal government and New York State are considered separate sovereigns, and the Double Jeopardy Clause does not prevent both from prosecuting the same conduct. In practice, dual prosecutions are relatively uncommon, but they do occur — particularly in cases involving drug trafficking, bank robbery, and organized crime.
Are federal sentences more severe than New York State sentences?
In most cases, yes. Federal mandatory minimum sentences, particularly for drug offenses and firearms charges, are often significantly longer than comparable state sentences. Federal sentences also lack the possibility of parole — defendants must serve at least 85% of their sentence under federal law. New York State allows greater judicial discretion in many non-violent cases and offers the possibility of probation for certain felony classes.
What should I do if I’m contacted by a federal agent?
If you are contacted by agents from the FBI, DEA, IRS, or any other federal agency, you should exercise your constitutional right to remain silent and contact a federal defense attorney immediately. Do not make any statements or agree to any interviews without legal counsel present. Federal investigations are often well advanced by the time agents make contact, and anything you say can and will be used against you.
Do I need a different lawyer for federal court than for state court?
Federal criminal defense requires specialized knowledge of federal rules of procedure, the U.S. Sentencing Guidelines, and the practices of the specific U.S. Attorney’s office handling the case. While many criminal defense attorneys are admitted to practice in both state and federal court, not all have meaningful experience handling federal matters. If you are facing federal charges, you should retain an attorney with demonstrated experience in the relevant federal district.
