Can Evidence Be Thrown Out? Understanding Illegal Search and Seizure

If you are facing criminal charges, the most important question you can ask is: Can evidence be thrown out? Understanding illegal search and seizure is the first step in protecting your freedom and holding law enforcement accountable for Constitutional violations. If the police gathered evidence against you by breaking the law, the team at Rubin Law, P.C. can fight to ensure that evidence never reaches a jury.

What Constitutes a Search and Seizure?

The Fourth Amendment of the U.S. Constitution protects citizens from “unreasonable searches and seizures.” But what does that actually mean in a modern legal context?

Defining “Search” and “Seizure” Under the Fourth Amendment

A search occurs when a government employee (like a police officer) looks into an area where a person has a “reasonable expectation of privacy.” A seizure occurs when the government takes control of a person or their property. This can range from an officer taking your backpack to the act of an arrest itself.

The Expectation of Privacy: Where Your Rights Apply

The law distinguishes between public and private spaces. You have the highest expectation of privacy inside your body and your home. You have a lower expectation of privacy in your car, and generally no expectation of privacy regarding things you leave on a public sidewalk or in a trash can on the street.

Understanding Probable Cause vs. Reasonable Suspicion

Police cannot act on a “hunch.” They must meet specific legal standards:

• Reasonable Suspicion: A lower standard that allows police to briefly stop and question you (a “Terry Stop”).
• Probable Cause: A higher standard. This requires specific facts that would lead a reasonable person to believe a crime has been committed or that evidence of a crime exists in a specific location.

When is a Search Considered Unconstitutional?

For a search to be legal, it generally needs to be “reasonable.” In most cases, the court defines “reasonable” as having a valid warrant.

The General Rule: Why Warrants are Required

A warrant is a document signed by a judge that gives police permission to search a specific location for specific items. To get one, police must provide an affidavit proving they have probable cause. If police search your home without a warrant—and no exception applies—the search is likely unconstitutional.

Stop and Frisks: The “Terry Stop” Standard

Police are allowed to “pat down” a person’s outer clothing if they have reasonable suspicion that the person is armed and dangerous. However, they cannot use this as an excuse to dig into your pockets for drugs or other non-weapon contraband unless it is immediately apparent by “plain feel” that the item is illegal.

Search and Seizure Parameters: Scope and Duration

Even a legal search has limits. If a warrant allows police to search your garage for a stolen motorcycle, they cannot legally open a small jewelry box. If the search goes beyond the “scope” defined in the warrant, the evidence found can often be thrown out.

Common Exceptions to the Warrant Requirement

The law recognizes that police cannot always wait for a judge. There are several major exceptions where a search is legal without a warrant.

Consent: What Happens if You Say “Yes”?

The simplest way for police to bypass the Fourth Amendment is to ask for permission. If you voluntarily agree to a search, you waive your Constitutional protections. You have the right to say, “I do not consent to searches,” and you should always exercise that right.

The Plain View Doctrine

If an officer is legally standing in a spot (like a public sidewalk or your front porch) and sees illegal items in plain sight, they can seize them without a warrant.

Exigent Circumstances: Emergency Situations

If there is an immediate threat to life, a risk that evidence will be destroyed, or a suspect is about to escape (hot pursuit), police can enter and search without waiting for a warrant.

Search Incident to Lawful Arrest

Once you are under arrest, police are allowed to search your person and the immediate area around you to ensure you aren’t carrying a weapon or trying to destroy evidence.

The “Good Faith” Exception: When Police Make Honest Mistakes

Sometimes, a warrant is technically flawed (like a typo in the address), but the police believed it was valid. If the court finds the officers acted in “good faith,” the evidence might still be allowed.

Search and Seizure in Specific Locations

Your Home or Apartment: The Most Protected Space

Your home is your castle. Except for extreme emergencies or valid consent, police almost always need a warrant to cross your threshold. This includes your backyard and porch in many cases.

Vehicles: Why Your Rights Change on the Road

Because cars are mobile, the Supreme Court has ruled that you have a lower expectation of privacy in a vehicle. Police only need probable cause—not a warrant—to search a car they have pulled over.

Public Spaces and Curtilage: Where Privacy Ends

“Curtilage” refers to the area immediately surrounding your home (like a fenced-in yard). While this area is protected, public spaces are not. If you are in a public park or walking down the street, police can use “open view” to observe your actions without violating your rights.

Modern Privacy: Digital Devices and Cell Phone Data

As technology evolves, so does the law. Today, your smartphone contains more personal information than your entire house.

Does the Police Need a Warrant for Your Phone Content?

In the landmark case Riley v. California, the Supreme Court ruled that police must have a warrant to search the digital contents of a cell phone, even if the owner is under arrest. They can seize the physical phone to prevent it from being wiped, but they cannot look at your photos, texts, or apps without a judge’s signature.

GPS Tracking and Geofence Warrants

Police sometimes use “geofence warrants” to ask tech companies for data on every phone that was in a certain area at a certain time. These are highly controversial and often successfully challenged by defense attorneys as overbroad.

Biometrics: Can You Be Forced to Unlock Your Phone?

This is a developing area of law. While you cannot be forced to give up your passcode (due to the Fifth Amendment protection against self-incrimination), some courts have allowed police to force suspects to use a fingerprint or face ID to unlock a device. This is why having an experienced attorney like those at Rubin Law, P.C. is vital.

The Remedy: How Evidence Gets Thrown Out

If your rights were violated, the evidence doesn’t just disappear automatically. Your lawyer must take action.

The Exclusionary Rule: Your Primary Defense

The Exclusionary Rule prevents the prosecution from using evidence gathered during an illegal search. If the evidence is excluded, it’s as if it never existed in the eyes of the court.

“Fruit of the Poisonous Tree”: How One Error Can Topple a Case

This legal metaphor explains that if the “tree” (the initial search) is poisoned/illegal, then any “fruit” (later evidence) coming from that tree is also tainted. For example, if police illegally search your car and find a map to a warehouse, the drugs found at the warehouse must also be thrown out because they were found only because of the first illegal search.

The Motion to Suppress: The Legal Vehicle for Removing Evidence

To get evidence thrown out, your attorney files a “Motion to Suppress.” This leads to a hearing where a judge listens to testimony from the police and the defense. If the judge agrees the search was illegal, they will grant the motion and suppress the evidence.

The Burden of Proof: What You Must Demonstrate in Court

If the search was conducted with a warrant, the defense must prove the warrant was invalid. If the search was conducted without a warrant, the burden shifts to the prosecution to prove that an exception (like consent or an emergency) made the search legal.

What to Do If Your Rights Were Violated

Immediate Steps to Take During and After the Search

Remain Calm: Do not physically resist the police, as this can lead to additional charges.

State Your Objection: Clearly say, “I do not consent to this search.”

Remain Silent: You are not required to explain what is in your car or home.

Document Everything: As soon as possible, write down exactly what happened, what was said, and which officers were involved.

How Evidence Suppression Changes Your Defense Strategy

When key evidence is suppressed—such as the weapon in a gun charge or the drugs in a possession case—the prosecutor often has no choice but to reduce the charges or dismiss the case entirely.

Civil Remedies: Can You Sue for an Unconstitutional Search?

Under a federal law known as Section 1983, you may be able to sue the police for violating your Constitutional rights. If the search was particularly egregious or involved police misconduct, you may be entitled to financial compensation for damages.

FAQ: People Also Ask

Can police search my trash?
Generally, yes. Once you place your trash at the curb for collection, the courts rule that you have abandoned your expectation of privacy.

Does “smelling weed” count as probable cause?
In many states, yes. However, in states where marijuana is legal or decriminalized, the “plain smell” doctrine is being heavily challenged in court.

Can my roommate give police permission to search my bedroom?
No. A roommate can usually only give consent to search “common areas” like the kitchen or living room. They cannot grant access to areas where you have an exclusive expectation of privacy, like your private bedroom or a locked safe.

What if the police had a warrant but the address was slightly wrong?
This falls under the “Good Faith” exception. If the mistake was minor and the officers reasonably believed they were at the right place, the search may still be considered legal.

Can police search my car if I’m only pulled over for a broken taillight?
Not without more information. A traffic violation alone does not give police the right to search your vehicle. They still need probable cause or your consent.
