Franks Hearing in Florida: How to Challenge False or Misleading Statements in a Search Warrant
A search warrant is supposed to be based on truthful information presented to a neutral judge.
But what happens if the affidavit supporting the warrant contains a false statement?
What if the officer leaves out an important fact that would have changed the probable-cause analysis?
In those circumstances, a defendant may be able to request what is commonly called a Franks hearing.
The name comes from Franks v. Delaware, 438 U.S. 154 (1978). The United States Supreme Court held that a defendant can challenge the truthfulness of factual statements in a search-warrant affidavit when the defendant makes a sufficient preliminary showing that the affidavit contains deliberately false or recklessly misleading information that was necessary to the probable-cause determination.
Florida courts also apply the Franks doctrine to material omissions from search-warrant affidavits. The Florida Supreme Court expressly addressed omissions in Johnson v. State, 660 So. 2d 648 (Fla. 1995).
A Franks hearing is therefore not simply an argument that police were wrong.
The issue is whether police misled the issuing judge in a constitutionally significant way.

What Is a Franks Hearing?
A Franks hearing is an evidentiary hearing where the defense challenges the truthfulness or completeness of information used to obtain a search warrant.
The defense may argue that the warrant affidavit contained:
- a deliberately false statement;
- a statement made with reckless disregard for the truth;
- a material omission;
- a misleading description of an informant;
- a materially inaccurate account of surveillance;
- false information about controlled buys;
- misleading statements about digital evidence;
- incorrect statements about what officers observed.
But not every mistake justifies a Franks hearing.
The defendant generally must first make a substantial preliminary showing that the challenged misstatement or omission was both sufficiently culpable and material to probable cause. Unlike traditional motions to suppress filed by the defense, the defense has the initial burden of proof in a Franks hearing.
Authority
- Franks v. Delaware, 438 U.S. 154 (1978)
The Two Core Requirements of a Franks Challenge
A Franks challenge usually involves two major questions.
1. Was the affidavit intentionally or recklessly false or misleading?
The defense must generally show more than negligence, confusion, or an innocent mistake.
The false statement must have been made:
- knowingly and intentionally; or
- with reckless disregard for the truth.
Florida courts apply the same basic principle.
In State v. Domenech, the Second District reiterated that a Franks claim requires more than an inaccurate affidavit. The defendant must establish that the false information rose above mere negligence and amounted to perjury or reckless disregard for the truth.
2. Was the false or omitted information material to probable cause?
Even a serious false statement will not necessarily invalidate a warrant if probable cause remains after correcting the affidavit.
The court effectively asks:
If the false statement is removed—or the omitted fact is added—does probable cause still exist?
If the answer is yes, suppression may not follow.
If the answer is no, the warrant can be invalidated.

A Franks Hearing Is Not Automatically Granted
A defendant is not automatically entitled to a full evidentiary hearing merely by alleging that the warrant affidavit was wrong.
The defense must first make a sufficient preliminary showing.
That typically requires identifying:
- the exact statement claimed to be false;
- the fact that was allegedly omitted;
- why the statement was knowingly or recklessly false;
- evidence supporting that claim;
- why correcting the affidavit would eliminate probable cause.
Conclusory accusations are usually not enough.
Federal courts applying Franks repeatedly emphasize that mere negligence or innocent mistake does not satisfy the standard.
What Is a “Substantial Preliminary Showing”?
The phrase comes from Franks.
Before receiving an evidentiary hearing, the defendant generally must provide more than speculation.
The motion should usually be supported by an offer of proof.
That may include:
- body-camera footage;
- police reports;
- dispatch recordings;
- photographs;
- witness affidavits;
- surveillance video;
- text messages;
- phone records;
- contradictory officer reports;
- controlled-buy documentation;
- informant records;
- forensic reports;
- other objective evidence.
The stronger the contradiction between the warrant affidavit and the objective evidence, the stronger the Franks claim may become.
Mere Negligence Is Not Enough
This is one of the most important limitations of Franks.
Suppose an officer accidentally writes that surveillance occurred at 4:00 p.m. when it actually occurred at 4:30 p.m.
That type of innocent mistake ordinarily does not invalidate a search warrant.
Franks is aimed at more serious conduct:
- intentional falsehood;
- reckless disregard for accuracy;
- deliberately misleading omission.
The Supreme Court expressly distinguished these situations from negligence and innocent mistake.
Authority
- Franks v. Delaware, 438 U.S. 154, 171 (1978)
What Does “Reckless Disregard for the Truth” Mean?
Recklessness falls between innocent negligence and deliberate lying.
The exact analysis is fact-specific.
Possible indicators might include an officer:
- asserting facts without any reasonable basis;
- repeating information after learning it was false;
- materially exaggerating what a witness said;
- presenting unverified information as confirmed fact;
- omitting facts that obviously undermine the affidavit;
- describing an informant as reliable despite knowing otherwise.
A strong Franks case often depends on proving not merely that a statement was wrong, but that the officer knew or should have appreciated the serious risk that the statement was false or misleading.
Can a Franks Hearing Be Based on Omissions?
Yes.
This is especially important in Florida.
In Johnson v. State, the Florida Supreme Court held that the Franks analysis can apply when police omit material facts from a probable-cause affidavit.
The Court described two key questions:
- Would the omitted material, if included, have defeated probable cause?
- Did the omission result from intentional or reckless police conduct amounting to deception?
If those requirements and the other Franks prerequisites are satisfied, a full evidentiary hearing may be ordered.
Authority
- Johnson v. State, 660 So. 2d 648 (Fla. 1995)
Examples of Potentially Important Omissions
A warrant affidavit may be misleading not because of what it says, but because of what it leaves out.
Examples might include failing to disclose that:
- a confidential informant has repeatedly provided inaccurate information;
- the informant received money or leniency;
- surveillance contradicted the informant;
- a witness recanted;
- officers did not actually observe a claimed transaction;
- laboratory testing contradicted an officer’s description;
- key timestamps did not match;
- another suspect had equal or stronger connection to the evidence;
- a controlled buy was not properly monitored;
- digital evidence came from a different device or account.
Whether an omission is material depends on whether including it would have changed the probable-cause determination.
False Statements About Confidential Informants
Informants are a frequent source of Franks litigation.
Police affidavits often rely on confidential sources to establish probable cause.
The affidavit may describe an informant as:
- reliable;
- previously proven trustworthy;
- personally familiar with criminal activity;
- corroborated by police investigation.
If those statements are false or misleading, the defense may have grounds to investigate a Franks challenge.
In Joshua v. State, the Fourth District discussed a defendant’s Franks request based on an affidavit that allegedly mischaracterized the source of information as a documented confidential informant who had previously provided reliable information.
Probable Cause in Florida Criminal Cases
What If the Informant Was Paid or Received Leniency?
The fact that an informant was compensated or cooperating for favorable treatment can be important.
But omission of that fact does not automatically invalidate a warrant.
The issue remains whether the omission was intentionally or recklessly misleading and whether inclusion of the omitted facts would have defeated probable cause.
Corroboration by independent police investigation may substantially affect that analysis.
Controlled Buys and Franks Hearings
Drug search warrants frequently rely on controlled buys.
An affidavit might state that:
- an informant was searched before the buy;
- police provided marked currency;
- officers maintained surveillance;
- the informant entered the target residence;
- the informant returned directly to officers;
- suspected drugs were recovered;
- the substance field-tested positive.
If body-camera video, surveillance reports, GPS data, or officer reports contradict those statements, defense counsel may examine whether the discrepancies rise to the level of Franks.
Potential questions include:
- Was continuous surveillance actually maintained?
- Could the informant have obtained drugs somewhere else?
- Was the informant searched adequately beforehand?
- Did the informant actually enter the identified residence?
- Did officers verify the suspected substance?
- Did the affidavit exaggerate what police actually observed?
False Statements About Surveillance
Search-warrant affidavits frequently describe surveillance as corroboration.
For example:
“Detectives observed multiple short-stay visitors consistent with narcotics trafficking.”
Defense counsel should ask what the officers actually documented.
Relevant evidence may include:
- surveillance logs;
- body camera;
- fixed surveillance video;
- license plate reader data;
- GPS records;
- timestamps;
- officer text messages;
- dispatch logs.
If objective records contradict the sworn affidavit, the discrepancy may deserve further investigation.
Franks Hearings and Search Warrants for Cell Phones
Franks issues can also arise in digital investigations.
A warrant application for a phone may rely on statements that:
- a particular number belonged to the defendant;
- the phone was used during the alleged crime;
- location data placed the defendant at a scene;
- messages connected the phone to criminal activity;
- another witness identified the device.
If those foundational assertions were materially false or misleading, the warrant itself may be subject to challenge.
See – Can Police Search Your Cell Phone in Florida? and Digital Evidence in Florida Criminal Cases.
Franks Hearings and Social Media Warrants
The same concept can apply to warrants seeking:
- Facebook accounts;
- Instagram messages;
- Google data;
- cloud backups;
- email;
- stored photographs;
- location information.
The defense should examine whether the warrant affidavit accurately described:
- account ownership;
- timestamps;
- user identity;
- IP information;
- metadata;
- connection between the account and alleged offense.
A mistaken assumption about who controlled an account can sometimes affect the probable-cause analysis.
Franks Hearings and Location Data
Digital location evidence can appear precise while actually depending on assumptions.
Affidavits may rely on:
- cell-site location information;
- GPS records;
- Google location data;
- tower connections;
- device identifiers.
Defense counsel may need to investigate whether the affidavit accurately described what the data actually established.
An affidavit that converts approximate location information into a falsely precise claim could create a significant issue depending on materiality and state of mind.
How Does the Court Test Materiality?
The court effectively reconstructs the affidavit.
For a false statement:
Remove the false information.
For an omission:
Add the omitted information.
Then ask:
Does the corrected affidavit still establish probable cause?
If probable cause remains, suppression may be denied even if the affidavit contained serious errors.
That is precisely why materiality is central to a Franks challenge.
In Domenech, the Second District emphasized that both culpability and materiality must be established.
Example of a False Statement That May Not Be Material
Suppose a warrant affidavit incorrectly states that police observed five suspected drug transactions.
Evidence later establishes there were only four.
If the remaining affidavit still includes:
- a reliable controlled buy;
- surveillance;
- corroborating statements;
- other evidence establishing probable cause;
the false statement may not be material.
Franks does not automatically invalidate an affidavit because it contains any inaccuracy.
Example of a Potentially Material False Statement
Now consider a different affidavit.
Police obtain a home search warrant almost entirely because the affidavit claims:
“A confidential informant purchased cocaine inside the residence within the last 48 hours.”
But video later establishes the informant never entered that residence.
If the controlled buy was the essential basis for probable cause, the false statement may be material.
Removing it could leave the affidavit without sufficient probable cause.
That is the type of situation in which a Franks challenge becomes much more significant.
Who Must Have Made the False Statement?
Franks traditionally focuses on falsehoods attributable to government actors involved in obtaining the warrant.
A difficult issue can arise when the affidavit accurately reports what a civilian witness said, but the civilian witness was lying.
An officer does not necessarily violate Franks merely because a witness gave false information if the officer truthfully reported what the witness said and did not knowingly or recklessly misrepresent its reliability.
The focus therefore often falls on the affiant’s conduct and state of mind.
What If One Officer Gives False Information to the Affiant?
A Franks problem cannot necessarily be avoided simply because one officer passes false information to another officer who signs the affidavit.
Courts may examine whether deliberate or reckless government misinformation was ultimately used to establish probable cause.
This is particularly relevant in multi-officer investigations where the affiant relies heavily on other detectives.
Does Franks Apply to Arrest Warrants?
The doctrine originated in the search-warrant context, but similar Fourth Amendment principles can arise when probable-cause affidavits supporting arrest warrants contain deliberately or recklessly false information.
The precise remedy and procedural posture can differ, so the issue should be analyzed based on the warrant involved and evidence obtained as a consequence.
How Is a Franks Challenge Different From a Normal Probable Cause Challenge?
These are related but distinct arguments.
Ordinary probable-cause challenge
The defense assumes the affidavit is accurate but argues:
“Even taking everything in the affidavit as true, it does not establish probable cause.”
Franks challenge
The defense argues:
“The issuing judge was given materially false or misleading information.”
A strong motion may raise both arguments.
See – Probable Cause in Florida Criminal Cases
How Is a Franks Hearing Different From Challenging Stale Information?
Staleness is another independent warrant issue.
A defendant may argue that information was too old to establish probable cause at the time the warrant was issued.
That does not necessarily mean the affidavit was false.
But if the officer deliberately altered or concealed dates to make old information appear recent, the issue could potentially become a Franks problem as well.
See – Search Warrants in Florida.
Does Franks Apply to Misleading Half-Truths?
Potentially.
An affidavit can sometimes be technically accurate yet materially misleading because important context is omitted.
For example:
“The informant previously provided information leading to an arrest.”
That statement may technically be true.
But if the officer omitted that the informant had also repeatedly provided false information or that the earlier case collapsed because the information was unreliable, the defense might examine whether the omission materially distorted the probable-cause picture.
The issue again turns on intentional or reckless deception and materiality.
What Evidence Should a Defense Lawyer Review?
A serious Franks investigation may require comparing the warrant affidavit against the complete investigative record.
That can include:
- offense reports;
- supplemental reports;
- body-camera footage;
- dash-camera footage;
- surveillance video;
- 911 calls;
- CAD records;
- recorded interviews;
- informant records;
- controlled-buy paperwork;
- evidence logs;
- laboratory reports;
- photographs;
- cell-phone extractions;
- digital metadata;
- GPS/location records;
- officer emails and messages;
- subpoena returns.
Small discrepancies can sometimes reveal larger problems.
Body-Camera Footage Can Be Especially Important
Body-camera footage may contradict an affidavit in ways that written reports do not.
For example, the affidavit might state:
“The defendant admitted ownership of the firearm.”
But the body-camera footage may show:
“The defendant denied ownership and said the firearm belonged to another person.”
That difference may matter if the alleged admission was central to probable cause.
See – Digital Evidence in Florida Criminal Cases.
Search Warrant Affidavit vs. Police Report
Defense counsel should compare these documents carefully.
Sometimes:
- the affidavit describes events more strongly than the original report;
- the report contains qualifying details omitted from the affidavit;
- times differ;
- witness statements change;
- officer observations evolve;
- uncertainty becomes certainty.
Those inconsistencies do not automatically establish Franks misconduct, but they can identify issues requiring further investigation.
What Happens at the Franks Hearing?
If the defendant satisfies the preliminary threshold, the court may conduct an evidentiary hearing.
The defense may present evidence concerning:
- the challenged statement;
- the omitted facts;
- the officer’s knowledge;
- the officer’s investigative steps;
- the materiality of the information.
The State may respond and offer its own evidence.
The judge ultimately determines whether the defendant has established the required showing.
What Is the Burden of Proof at the Hearing?
After a Franks hearing is granted, the defendant generally must establish the deliberate or reckless falsehood by a preponderance of the evidence.
If that burden is met, the court then evaluates the corrected affidavit.
If the remaining affidavit no longer establishes probable cause, the search warrant must be invalidated and the fruits of the search are subject to exclusion.
Domenech recently reiterated that rule in Florida.
Authority
- Franks v. Delaware, 438 U.S. 154 (1978)
- State v. Domenech
What Happens If the Defendant Wins?
If the defendant establishes:
- intentional or reckless falsehood or omission; and
- the corrected affidavit lacks probable cause,
the warrant may be voided.
Evidence obtained under the warrant can then be suppressed to the same extent as if the warrant lacked probable cause from the outset.
This can include:
- drugs;
- firearms;
- documents;
- phones;
- digital evidence;
- statements derived from the search;
- evidence discovered as a result of the search.

- Wong Sun v. United States, 371 U.S. 471 (1963)
See – Motion to Suppress Evidence in Florida.
Does Winning a Franks Hearing Automatically Dismiss the Case?
No.
Suppression and dismissal are different questions.
If critical evidence is suppressed, the prosecution may no longer have enough admissible evidence to proceed.
That can sometimes lead to:
- dismissal;
- nolle prosequi;
- reduced charges;
- improved plea negotiations.
But the case may continue if sufficient independent evidence remains.
What About the Good-Faith Exception?
Prosecutors may sometimes argue the good-faith exception under United States v. Leon.
But good faith is not unlimited.
Leon itself identified situations in which reliance on a warrant may not qualify as objectively reasonable, including when an issuing judge was misled by information the affiant knew was false or would have known was false except for reckless disregard for the truth.
That makes Franks and Leon closely connected.
Authority
- United States v. Leon, 468 U.S. 897 (1984)
- Franks v. Delaware, 438 U.S. 154 (1978)
Franks Hearings and the Good-Faith Exception
If police themselves intentionally or recklessly mislead the judge, the State should have difficulty arguing that officers acted in objective good faith by relying on the warrant they improperly obtained.
That is very different from an officer reasonably relying on a warrant later determined to contain a technical legal defect.
Can a Search Warrant Be Challenged Without a Franks Hearing?
Yes.
A search warrant may be challenged for many reasons, including:
- lack of probable cause;
- stale information;
- lack of nexus;
- overbreadth;
- insufficient particularity;
- unconstitutional execution;
- improper nighttime search;
- Franks violations.
A Franks hearing is therefore one potential component of a broader motion to suppress.
See – Search Warrants in Florida and Motion to Suppress Evidence in Florida.
Current Florida Motion to Suppress Procedure
Under current Florida Rule of Criminal Procedure 3.190(g), a defendant may move to suppress evidence or statements obtained unlawfully.
A suppression motion should identify the evidence being challenged, the legal basis for suppression, and the supporting facts.
For a Franks claim, specificity is especially important because the defendant must identify the alleged falsehood or omission and establish why it matters to probable cause.
Authority

Frequently Asked Questions About Franks Hearings in Florida
What is a Franks hearing?
A Franks hearing is an evidentiary hearing used to challenge materially false or misleading statements or omissions in a warrant affidavit.
Authority: Franks v. Delaware, 438 U.S. 154 (1978).
Does every mistake in a search-warrant affidavit invalidate the warrant?
No. Negligence and innocent mistakes generally do not satisfy Franks.
Authority: Franks v. Delaware.
Can omitted facts support a Franks hearing in Florida?
Yes. Florida’s Supreme Court has expressly applied Franks to material omissions caused by intentional or reckless police conduct amounting to deception.
Authority: Johnson v. State, 660 So. 2d 648 (Fla. 1995).
What must I show to get a Franks hearing?
Generally, the defense must make a substantial preliminary showing that a material falsehood or omission was made intentionally or with reckless disregard for the truth and mattered to probable cause.
What if an officer simply made a typo?
An innocent clerical mistake normally does not satisfy the Franks standard.
What if police lied about a confidential informant?
That can potentially support a Franks claim if the misrepresentation was intentional or reckless and material to probable cause. Florida appellate courts have addressed Franks claims involving how informant information was presented.
Can a Franks hearing challenge a cell-phone warrant?
Yes. The doctrine can apply when materially false or misleading information is used to establish probable cause for a digital search warrant.
What happens if the false statement is removed but probable cause still exists?
The warrant generally remains valid under Franks because the false information was not material to the probable-cause determination.
What happens if the corrected affidavit does not establish probable cause?
If the defendant satisfies the other Franks requirements, the warrant may be voided and resulting evidence suppressed.
Does suppression automatically dismiss the case?
No. The effect depends on what admissible evidence remains.
Franks Hearings in Gainesville and North Florida Criminal Cases
Franks issues can arise in many types of investigations, including:
- narcotics cases;
- firearm investigations;
- home search warrants;
- trafficking cases;
- child pornography investigations;
- cell-phone warrants;
- social-media warrants;
- theft and fraud investigations;
- homicide investigations;
- digital-evidence cases.
In Gainesville and Alachua County, warrant applications may involve investigators from the Gainesville Police Department, Alachua County Sheriff’s Office, University of Florida Police Department, Florida Department of Law Enforcement, or other agencies.
The same constitutional protections apply in Bradford, Levy, Gilchrist, Marion, Putnam, Columbia and throughout North Florida.
A warrant signed by a judge should not automatically end the defense investigation.
The critical questions may become:
What was the judge told? → Was it accurate? → What was left out? → Did police know better? → Would the judge still have found probable cause with a truthful and complete affidavit?
