In South Carolina DUI cases, defense attorney Michael L. Brown, Jr. (serving Rock Hill, SC) uses motions to suppress to protect his clients whenever possible. Suppressing key evidence can help prevent prosecutors from meeting their burden of proof—which can potentially lead to pre-trial dismissal. For example, by filing motions to suppress focused on Fourth Amendment violations during warrantless vehicle searches or flaws in “probable cause” affidavits in York County, MLB Law can work to exclude illegally gathered evidence from trial.
As a defendant in South Carolina’s criminal justice system, you are entitled to the full protections afforded by the U.S. Constitution. This includes the protection against receiving an unfair trial. As a result, if prosecutors are planning to use evidence that was obtained in violation of your other constitutional rights (i.e., the Fourth Amendment protection against unreasonable searches and seizures), you may be entitled to have this evidence suppressed from your trial.
Why is this important? It is important because the prosecution has the burden of proof. In order to secure a DUI conviction, prosecutors must be able to present sufficient evidence to convince the judge or jury that you are guilty beyond a reasonable doubt. If prosecutors can’t use their evidence against you, they won’t be able to meet this burden—and this means they won’t be able to secure a conviction.
Challenging “Reasonable Suspicion” in York County
While there are several potential grounds for filing a motion to suppress in a DUI case in York County, two of the most common reasons are: (i) lack of “reasonable suspicion;” and, (ii) lack of “probable cause.” Under the Fourth Amendment, the police must have reasonable suspicion in order to conduct a traffic stop.
Specifically, they must have reasonable suspicion that you have violated the law. This doesn’t necessarily mean that they need to pull you over on suspicion of DUI, but it does mean that they need to have a law enforcement-related reason for pulling you over. If the police racially profiled you or stopped you for any other unlawful reason, this could serve as clear grounds for a motion to suppress.
Challenging “Probable Cause” in York County
In addition to having reasonable suspicion to conduct a traffic stop, the police must also have probable cause to make an arrest. “Probable cause” is a higher standard than “reasonable suspicion.” If the police arrested you without probable cause, this is a clear violation of your Fourth Amendment rights, and you could have clear grounds to file a motion to suppress in this scenario as well.
Crucially, if the police didn’t have probable cause to conduct an arrest but they did have reasonable suspicion to pull you over, then some of the prosecution’s evidence may still be admissible. Specifically, prosecutors may still be able to use any evidence obtained prior to your unconstitutional arrest. This is critical to keep in mind—and, when you speak with a DUI defense lawyer about your case, it will be important for you to provide your lawyer with as many details about your traffic stop as possible.
Invalidating Warrantless Search Affidavits
As a general rule, probable cause is also required for a search warrant. However, the U.S. Constitution allows the police to conduct warrantless searches in some cases. For example, during a DUI stop in York County, the police may be able to conduct a warrantless search based on:
- The DUI suspect’s consent (even if the suspect did not realize he or she had the right to refuse)
- A search incident to arrest
- The “plain view” exception or the automobile exception
While the police can conduct warrantless searches in certain circumstances, after conducting a warrantless search, the police must generally prepare an affidavit or sworn statement attesting to the constitutional basis for the search. Challenging the claims made in a warrantless search affidavit can be essential for keeping evidence out of court—and, from deficiencies to false statements, there may be several grounds for doing so.
The Exclusionary Rule in 2026: Targeting Pre-Trial Dismissal By Filing a Motion to Suppress
The exclusionary rule prohibits prosecutors from using unconstitutionally obtained evidence during a DUI trial in York County. However, when the exclusionary rule applies, it is up to defendants to assert their legal rights effectively. This means that DUI defendants must file a motion to suppress when warranted, and they must be able to convince the court that the constitutional issue (or issues) at hand warrant excluding relevant evidence from trial.
As noted above, while filing a motion to suppress can keep key evidence out of trial, it can also set the stage for a pre-trial motion to dismiss. If prosecutors do not have the evidence they need to convict you, you should not be forced to go through the trial process.
Suppression as a Defense Foundation in South Carolina Criminal Cases
Even if the circumstances are such that pre-trial dismissal of your DUI charge isn’t warranted, filing a motion to suppress could still be a foundational element of your overall defense strategy. The less evidence prosecutors have against you, the harder it will be for them to meet their burden of proof.
Defending against a DUI charge in York County often requires a multi-faceted approach; and, even if the prosecution has admissible evidence against you, you may still be able fight your DUI charge through other means. For example, breathalyzer and field sobriety test (FST) results can both be called into question on various grounds. An experienced York County DUI defense lawyer will be able to build a comprehensive defense strategy focused on the specific facts of your case and fight to protect you by all means available.
