Exigent Circumstances and Search Warrants

Posted by Dmitry Gorin | Jun 17, 2025

The Fourth Amendment, a pivotal element of our legal system, safeguards individuals against 'unreasonable searches and seizures' by mandating that law enforcement and investigators secure a valid warrant before conducting any search or seizure. This crucial amendment also necessitates the demonstration of probable cause to obtain the warrant.

Over time, case law has introduced several exceptions to this rule, one of which is the concept of 'exigent circumstances,' allowing for immediate entry. This dynamic evolution of case law is a key factor in understanding the legal landscape.

Exigent Circumstances and Search Warrants
Exigent circumstances require swift action from law enforcement without time for a obtain search warrant.

In California, law enforcement frequently cites exigent circumstances as a valid reason to conduct a warrantless search, but what qualifies may vary from case to case. This can lead to potential overreach by law enforcement and a violation of constitutional rights.

Simply put, exigent circumstances require swift or immediate action, usually by law enforcement or federal agents. This can be an exception to the Fourth Amendment requirement that police officers have a valid warrant before conducting a search and seizure.

Courts typically state that exigent circumstances are present if a reasonable person would believe that prompt action was necessary to prevent bodily harm to someone, destruction of property or evidence, or the escape of a suspect.

Definition of Exigent Circumstances

Exigent circumstances are defined as "circumstances that would cause a reasonable person to believe that entry, or other relevant prompt action, was necessary to prevent physical harm to the officers or other persons, the destruction of relevant evidence, the escape of the suspect, or some other consequence improperly frustrating legitimate law enforcement efforts."

Due to the ambiguity involved, a skilled criminal defense attorney often focuses on the so-called exigent circumstances to argue for suppressing any evidence obtained from a warrantless search, thereby providing a crucial safeguard for individuals' constitutional rights.

Exigent circumstances refer to situations where law enforcement officers reasonably believe that immediate action is necessary due to an urgent situation, rendering the delay in securing a warrant impracticable or dangerous.

Court's Review of Warrantless Search

Courts will typically examine the time when the officer makes the warrantless search or seizure to evaluate whether, at that point in time, a reasonable officer at the scene would believe it urgent to act and impractical to secure a warrant.

Courts might also consider whether the facts suggested that the suspect was armed and planning to escape, whether a reasonable police officer would believe their safety was threatened, and whether there was a serious crime involved.

Exigent circumstances may also arise when law enforcement is in hot pursuit of a suspect who is possibly involved in criminal activities and is fleeing. The most common reasons an officer will cite exigent circumstances include:

  • Preventing the imminent destruction of evidence,
  • Preventing the suspect's escape, or
  • Preventing bodily harm or wanton destruction of property.

For example, suppose police, while in hot pursuit of a suspect believed to have illegal substances, observe the suspect running into a house. They can enter the house without a warrant to prevent the suspect from flushing the drugs down the toilet.

Fraught with Vagueness

In California, the legal framework acknowledges exigent circumstances as a legitimate basis for bypassing the traditional warrant requirement. However, despite its clear importance, exigent circumstances are also fraught with vagueness.

Warrantless Search

What constitutes an "immediate action" or an "emergency" is not always clear-cut, leaving considerable room for interpretation. Officers must sometimes make split-second decisions based on the information available to them at the moment.

While the flexibility of exigent circumstances is necessary for effective policing, it also opens the door to potential misuse or misinterpretation of the law. Officers might cite exigent circumstances in situations where the urgency or necessity may not be objectively justifiable, underscoring the need for caution and awareness among the public.

Law enforcement can misinterpret or wrongfully cite exigent circumstances to violate individuals' constitutional rights. Using the pretext of exigent circumstances for entry without a warrant in scenarios lacking genuine urgency undermines the Fourth Amendment protections against unreasonable searches and seizures. This violation can lead to the exclusion of evidence, dismissal of charges, or civil liability, underscoring the need for a clear understanding of exigent circumstances.

If there were not, in fact, exigent circumstances that justified a speedy entry, then the resulting evidence is obtained unlawfully and should legally not be admissible at trial.

Common Defense Strategies

Given the potential for misuse and the inherent ambiguity surrounding exigent circumstances, California criminal defense lawyers often find valid legal ground to challenge the legality of warrantless searches and seizures. In defending a client accused of a crime where exigent circumstances are cited as the basis for a warrantless search or arrest, a defense lawyer can explore several avenues, including:

  • Challenging the Existence: The defense can argue that the situation did not meet the legal criteria for exigent circumstances. For instance, that there was no immediate danger, no imminent risk of evidence destruction, or no credible threat of the suspect's escape. 
  • Reasonableness of Police Action: Even if exigent circumstances existed, the defense might challenge whether the officers' actions were reasonable and proportional to the situation. The defense attorney plays a crucial role in this, advocating for the defendant's rights and ensuring that law enforcement's actions are scrutinized for their reasonableness.
  • Alternative Measures: Demonstrating that law enforcement had viable alternatives to a warrantless search or arrest can further undermine the justification of exigent circumstances.

The ability to challenge the legitimacy of exigent circumstances is often a critical element in a criminal defense case. An experienced lawyer can review the facts of your case and determine whether law enforcement had valid reasons for conducting a warrantless search or arrest.

Evidence May Be Excluded

Suppose the defense successfully argues against the existence of exigent circumstances. In that case, the evidence obtained from the warrantless search may be excluded, leading to the dismissal of charges or a favorable outcome for the defendant.

Criminal Defense Lawyers

This underscores the crucial role of a skilled criminal defense attorney in protecting individuals' constitutional rights and ensuring that law enforcement does not overstep its bounds in the name of exigent circumstances.

If the attorney can demonstrate that officers or investigators did not have a reasonable expectation of urgency, they can refute the claim of exigent circumstances. If the attorney can successfully challenge the claim of 'exigent circumstances', it follows that the search and seizure violated your Fourth Amendment rights.

 As a result, any evidence obtained through that search must be suppressed and excluded from the trial, which could potentially lead to the dismissal of charges. If the evidence obtained is critical to the prosecution's case, the charges may even be dismissed, offering a glimmer of hope in an otherwise challenging situation. 

This could significantly alter the outcome of the case, demonstrating the power of understanding and challenging the concept of exigent circumstances in a legal defense. For additional information, contact our criminal defense law firm, Eisner Gorin LLP, located in Los Angeles, CA.
