DETENTION HEARINGS IN ILLINOIS: UNDERSTANDING THE NEW CASHLESS BAIL SYSTEM AND YOUR RIGHTS
Illinois’ criminal justice system changed dramatically with the passage of the Pretrial Fairness Act, which eliminated cash bail beginning in 2023. What used to be called bond hearings or bail hearings are now referred to as detention hearings or first appearance court. Instead of determining how much money a person must pay to get out of jail, judges now decide whether a person should be detained or released based on risk rather than finances.
The intent behind the new law was to create a fairer system, but the reality has proven far more complicated. Many defendants are still being detained before trial, sometimes for reasons that would not have kept them in custody under the old system. In Cook County, detention hearings have become one of the most critical stages of a criminal case.
With prosecutors seeking detention more aggressively than expected, it is essential to have an experienced criminal defense attorney at your side from the very first court appearance. Andrew M. Weisberg is a former Cook County prosecutor who understands how detention petitions are prepared and how to challenge them effectively. Early and aggressive representation can make the difference between going home and remaining in custody for months while your case is pending.
Understanding Detention Hearings Under the New Law
Under Illinois’ current pretrial release system, judges no longer set monetary bail. Instead, at the first court appearance, the judge must determine whether a defendant will be released or detained based on a petition filed by the prosecution.
Detention is not automatic. The State must formally request detention and explain why it believes a defendant should remain in custody.
If prosecutors seek detention, the judge must hold a detention hearing where both sides present arguments and evidence. After hearing the arguments, the judge will decide whether the defendant should be released under conditions or detained pending trial.
Key features of detention hearings include:
• Prosecutors must file a written petition explaining why detention is necessary
• Judges decide whether to order release or detention
• The prosecution has the burden of proof
• Defense attorneys can challenge the evidence and argue for release
• Witnesses and mitigation evidence may be presented
• Judges may impose conditions instead of detention
If detention is granted, the defendant remains in custody until trial or until a later court order allows release. If detention is denied, the defendant is released subject to court-ordered conditions.
Certain charges are much more likely to result in detention petitions, including:
• Firearm offenses
• Domestic violence cases
• Sex offenses
• Violent felony charges
• Repeat offenders
• Cases involving alleged threats or injuries
Because detention hearings happen quickly after arrest, preparation time is limited. Having an attorney involved immediately can significantly improve the chances of release.
The Detention Hearing Process in Illinois
Every detention hearing follows a structured legal process.
Arrest and First Appearance
After an arrest, the accused typically appears before a judge within 24 to 48 hours. This appearance takes place in first appearance court, which was previously known as bond court.
At this stage, prosecutors decide whether to request detention.
Prosecutor’s Petition for Detention
If prosecutors seek to keep a defendant in custody, they must file a written petition outlining their reasons.
The petition usually alleges that the defendant poses either:
• A threat to the safety of a person or the community
• A risk of failing to appear in court
The petition may rely on police reports, witness statements, and criminal history information.
Evidence and Arguments
During the hearing, both sides present arguments.
Prosecutors may rely on:
• Police reports
• Alleged statements
• Criminal history
• Digital evidence
• Witness accounts
The defense may:
• Challenge the State’s version of events
• Highlight weaknesses in the evidence
• Present mitigating information
• Explain ties to the community
• Demonstrate employment and family responsibilities
• Propose conditions of release
Judge’s Determination
The judge must decide whether the prosecution met its burden.
If detention is denied, the defendant is released.
If detention is granted, the defendant remains in custody pending trial or further court review.
Conditions of Release
If a defendant is released, conditions may include:
• Electronic monitoring
• Stay-away orders
• Curfews
• Travel restrictions
• Check-ins with pretrial services
• No-contact orders
If someone is released on bond and they fail to comply with the terms and conditions of the release, the individual will likely faces charges of violation of bail bond. Additionally, if a defendant is placed on electronic monitoring and breaks of the ankle bracelet, the person may be charged with escape.
Conditions are intended to reduce risk while allowing the defendant to remain in the community.
Tougher Enforcement Under the New Cook County State’s Attorney
The end of cash bail was expected to reduce the number of people held before trial. However, changes in prosecutorial policies have made detention hearings more contested than ever.
Cook County prosecutors are now seeking detention in more cases than initially anticipated.
This has resulted in:
• More petitions for detention
• More defendants held in custody
• Fewer releases on electronic monitoring
• More aggressive arguments for detention
Detention hearings have become one of the highest-stakes moments in a criminal case. A strong presentation at the first appearance can determine whether a person spends months in jail awaiting trial.

Frequently Asked Questions About Detention Hearings in Cook County
What is a detention hearing in Illinois?
A detention hearing—also called a pretrial release hearing—is where a judge decides whether a person charged with a crime will be released pending trial or detained in custody. The hearing must occur within 48 hours of arrest (excluding holidays and weekends) unless the State requests more time to file a petition. The judge reviews the charges, the evidence in the petition, and any risk factors before deciding on release or detention.
What factors does the judge consider at a detention hearing?
A judge considers the nature of the offense, the defendant’s criminal history, whether any alleged victims were harmed, risk of flight, and any prior failures to appear. The judge also evaluates whether conditions such as electronic monitoring, stay-away orders, or other restrictions could reasonably assure safety and court compliance.
What is the State required to prove at a detention hearing?
The prosecution must prove by clear and convincing evidence that no set of pretrial release conditions could prevent harm to a person or the community or ensure the defendant’s appearance in court. This is a high burden, but prosecutors in Cook County routinely seek detention for violent offenses, weapons cases, sex offenses, and some repeat offenders.
Can the defense present evidence at a detention hearing?
Yes. The defense can present mitigating evidence, proffers, documentation, background information, witnesses, or argument showing that the defendant can safely be released with conditions. A skilled defense attorney can push back against the State’s allegations and highlight weaknesses in the petition.
If the judge denies pretrial release, can it be appealed?
Yes. Illinois allows a defendant to file a motion to reconsider or appeal the detention decision. An attorney with experience in detention review hearings can argue for release based on changed circumstances or legal errors in the original ruling.
How quickly does the detention hearing happen after arrest?
Most detention hearings occur within 24–48 hours of arrest. This is why immediate legal representation is essential. The defense has very little time to prepare, and early involvement allows an attorney to begin gathering favorable information right away.
What types of cases most commonly lead to detention requests?
Cook County prosecutors frequently seek detention in cases involving firearms, violent crimes, domestic violence, sex offenses, and defendants with multiple recent arrests. Non-violent offenders and first-time offenders often have a stronger chance at release with effective representation.
Does Cook County handle detention hearings differently from other counties?
Yes. Cook County’s procedures under the Pretrial Fairness Act are extensive and differ from other counties. The volume of cases, structure of first appearance courts, and tendencies of individual judges create unique dynamics. Having a lawyer who regularly appears at 26th Street and suburban district courts is a major advantage.

Yes. Detention decisions often depend heavily on the judge hearing the case. Attorneys who routinely appear in Cook County understand how to tailor arguments to maximize the chance of release.
