BAY AREA SEARCH AND SEIZURE  LAWYERS

Some of the most significant powers that the police have are to search people and private property, and to seize property as evidence. It is important to understand exactly what the bounds of these powers are, however, because if the police step over the line and operate outside the law, there are consequences and ramifications in criminal cases. In cases where criminal accusations are made, Summit Defense Attorneys will not hesitate to challenge police actions. Our criminal defense attorneys will seek to suppress evidence obtained through improper or illegal police action.

Our firm has more than 120 years of cumulative criminal defense experience. We use our combined knowledge and reputation to fight against illegal searches. We are with you every step of the way, ensuring you understand the nuances of illegal police action as we create a defense strategy that protects your future and your freedom.

What Is an Illegal Search and Seizure?

An illegal search and seizure occurs when police or government officials intrude on your privacy or take property in violation of the Fourth Amendment.

A search includes any government intrusion into areas where you have a reasonable expectation of privacy, such as:

  • Your home, apartment, or hotel room
  • Your office or place of business
  • Your personal belongings, including bags or cell phones
  • Pat-downs or body searches
  • Vehicle stops and car searches

A seizure occurs when the government meaningfully interferes with your possession of property, including taking items as evidence during a search.

If law enforcement conducts an unlawful search or seizure, an experienced illegal search and seizure attorney may be able to have that evidence excluded.

The Fourth Amendment & Search and Seizure Law

The Fourth Amendment to the United States Constitution protects individuals from unreasonable searches and seizures. It provides:

“The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause…”

This constitutional protection is the foundation for challenging unlawful police conduct in criminal cases.

The Knock-and-Announce Rule

Even with a warrant, police must generally follow proper procedures when entering a home or business. This includes:

  • Knocking on the door
  • Announcing themselves as law enforcement
  • Stating that they have a warrant
  • Giving occupants time to respond

If police force entry without complying with this rule, the search may be unlawful unless an exception applies.

Exceptions to Knock-and-Announce

Courts recognize limited exceptions, such as:

  • Consent from the occupant
  • Public places already open to entry
  • Exigent circumstances (risk of danger or destruction of evidence)

Can Evidence Be Suppressed After an Illegal Search

Yes. If police violate the Fourth Amendment, your attorney can file a motion to suppress evidence under California Penal Code § 1538.5.

This motion may argue that:

  • The warrant was defective
  • There was no probable cause
  • Police exceeded the scope of the search
  • Officers violated constitutional standards during execution

If the court agrees, the search may be declared unlawful and the evidence excluded.

Suppressing evidence can lead to reduced charges or even dismissal of the case entirely.

Warrantless Searches and Common Exceptions

Although warrants are normally required, police sometimes claim exceptions that allow searches without one. Common examples include:

  • Exigent circumstances (emergency situations)
  • Consent searches
  • Search incident to arrest
  • Automobile exception
  • Plain view seizures
  • No reasonable expectation of privacy

However, these exceptions are often misused. A skilled illegal search and seizure lawyer can challenge whether the police truly had lawful justification.

Illegal Vehicle Stops and Searches

Police frequently stop and search vehicles, but they cannot do so without legal grounds.

Reasonable Suspicion for Traffic Stops

Officers must have reasonable suspicion that a traffic violation or criminal activity occurred. Stops based on race, profiling, or unsupported hunches may be unlawful.

Probable Cause for Vehicle Searches

To search a vehicle, police must generally have probable cause that it contains evidence of a crime.

If a stop or search was unlawful, evidence found in the vehicle may be suppressed.

How Summit Defense Attorneys Fights Illegal Searches

Summit Defense Attorneys is the largest criminal defense firm in the Bay Area, with extensive experience challenging unconstitutional police conduct.

Our attorneys fight illegal searches and seizures by:

  • Filing motions to suppress evidence
  • Investigating officer misconduct
  • Seeking internal police records
  • Negotiating for reduced or dismissed charges
  • Litigating suppression issues before trial
  • Appealing improper evidence rulings
  • Ensuring unlawfully seized property is returned

We believe no one should face conviction based on illegally obtained evidence.

Landmark Fourth Amendment Cases We Use to Challenge Illegal Searches

Summit Defense Attorneys defends clients against unconstitutional police conduct by relying on major U.S. Supreme Court and California court rulings that define the limits of lawful searches and seizures.

Key precedents include:

  • Terry v. Ohio (1968), which established that police must have reasonable suspicion before stopping or detaining someone
  • Chimel v. California (1969), limiting how far officers may search beyond the immediate area of an arrest
  • Horton v. California (1990), clarifying when evidence may be seized under the “plain view” doctrine
  • United States v. Jacobsen (1984), defining when government intrusion becomes a Fourth Amendment search
  • People v. Williams (1999), reinforcing that warrantless searches are presumed unlawful unless clearly justified

California law also provides powerful statutory protections, including:

  • Penal Code § 1538.5, the primary tool for filing motions to suppress illegally obtained evidence
  • Penal Code §§ 1524–1528, governing when and how search warrants may be issued
  • Penal Code § 1531 and People v. Ramsey (1988), addressing proper warrant execution and knock-and-announce requirements

These authorities form the legal foundation for challenging unlawful police searches, suppressing evidence, and pursuing dismissal or reduction of criminal charges whenever constitutional rights have been violated.

FAQs About Illegal Search and Seizure Cases

What qualifies as an illegal search and seizure?

An illegal search and seizure occurs when police or government officers search your home, vehicle, phone, or personal property without proper legal authority. This often involves violations of the Fourth Amendment, such as searches conducted without a valid warrant or without a lawful exception.

What happens if police search without a warrant?

In most cases, police must obtain a warrant before conducting a search. If they search without one, the search is presumed unlawful unless prosecutors can prove an exception applies, such as consent or exigent circumstances.

Can evidence be thrown out after an illegal search?

Yes. If law enforcement violated your constitutional rights, your attorney can file a motion to suppress evidence under California Penal Code § 1538.5. If the motion is granted, the court may exclude the evidence, which can lead to reduced charges or dismissal.

What is a motion to suppress evidence?

A motion to suppress is a legal request asking the court to exclude evidence obtained through unconstitutional or improper police conduct. This is one of the most powerful defenses in illegal search and seizure cases.

Do I have to consent to a police search?

No. You are not required to give officers permission to search your home, car, or belongings. If you do consent, it may eliminate your ability to challenge the search later, so it is important to speak with an attorney immediately.

What are common exceptions to the warrant requirement?

Police may claim certain exceptions, including:

  • Consent
  • Exigent circumstances (emergencies)
  • Search incident to arrest
  • Automobile exception
  • Plain view seizures

These exceptions are often challenged in court when misused.

Can police search my car during a traffic stop?

Police may stop a vehicle only with reasonable suspicion of a violation. To search the car, they generally need probable cause that evidence of a crime is inside. Unlawful stops or searches can result in evidence being suppressed.

How do I know if my Fourth Amendment rights were violated?

If police searched you, your property, or your vehicle without a warrant, without consent, or without a valid legal reason, your rights may have been violated. An experienced illegal search and seizure lawyer can review the facts and determine whether evidence can be excluded.

How can a Bay Area illegal search and seizure lawyer help?

A lawyer can challenge unlawful police conduct by:

  • Filing motions to suppress evidence
  • Investigating officer misconduct
  • Arguing Fourth Amendment violations in court
  • Seeking dismissal or reduction of charges

Summit Defense Attorneys has extensive experience defending clients in Bay Area search and seizure cases.

Should I contact an attorney immediately after an illegal search?

Yes. Illegal search and seizure defenses are time-sensitive, and early legal intervention can make the difference in suppressing evidence and protecting your future.
