How Often Does a Motion to Suppress Work?

How Often Does a Motion to Suppress Work? – If you’re caught up in a legal situation and hearing the term “motion to suppress” being used, you’re probably wondering, “How often does this actually work?” It sounds like something that could really help your case, but what are the chances that it’ll actually succeed?

In this article, we’re going to dive into what a motion to suppress is, how often it works, and the factors that can make or break this type of motion. Whether you’re a law student, someone facing criminal charges, or just curious, this guide will break it all down in simple, understandable terms.

What Is a Motion to Suppress?

Let’s start with the basics. A motion to suppress is basically a legal request that asks the court to exclude certain evidence from being used in trial. Most often, this motion is filed when a defendant believes that evidence was obtained in violation of their constitutional rights. The Fourth Amendment is key here—it protects you against unreasonable searches and seizures.

So, for instance, if law enforcement didn’t have a warrant or probable cause to search your car or home, you could file a motion to suppress any evidence they found during that search. The motion is saying, “Hey, this evidence shouldn’t be used against me because it was gathered in an illegal way.”

How Often Does a Motion to Suppress Actually Work?

Here’s where it gets interesting: motions to suppress don’t always succeed. In fact, they’re granted in about 10% of criminal cases, according to studies from the National Institute of Justice. That’s not to say that they’re useless—motions to suppress can be a critical tool in defending yourself, especially when evidence has been gathered improperly. But statistically speaking, they don’t work as often as people might hope.

So, why is that? Why do some motions to suppress succeed, while others don’t? The answer lies in a few different factors, which we’ll dive into below. Let’s take a look at what makes the difference between a motion that gets granted and one that gets denied.

Key Factors That Influence How Often a Motion to Suppress Works

1. The Specifics of the Search or Seizure

First and foremost, the success of a motion to suppress depends heavily on the details of the search or seizure that led to the evidence in question. Was there a warrant? Did the officers have probable cause? Or did they search without permission or justification?

If the search clearly violated your constitutional rights—for example, if it happened without a warrant or without reasonable suspicion—the chances of the motion succeeding go up. But, if law enforcement had a legitimate reason for conducting the search, the motion is likely to be denied.

2. The Strength of the Legal Argument

Like most things in law, the quality of your legal argument matters. If you have a skilled attorney who can build a strong case showing how your rights were violated, the motion to suppress has a better chance of being successful. A well-crafted motion will cite relevant case law and demonstrate why the evidence shouldn’t be allowed in court.

On the flip side, if the defense can’t show that the search was unlawful or if the argument isn’t backed up with solid legal reasoning, the motion will probably fail. The prosecution will also have a chance to argue that the evidence should be admitted, and it’s up to the judge to decide whether the violation was significant enough to warrant suppression.

3. The Type of Evidence Involved

Not all evidence is created equal. The kind of evidence at stake can make a big difference in how likely the motion to suppress is to succeed. Physical evidence obtained during an unlawful search (like drugs, weapons, or stolen property) is more likely to be suppressed than something like testimony that’s more abstract and harder to tie to an illegal search.

However, if the evidence is crucial to the prosecution’s case—like evidence that proves guilt beyond reasonable doubt—the chances of the motion succeeding could be lower. Courts will sometimes hesitate to suppress evidence if it’s central to the case, unless the violation of rights was particularly egregious.

4. The Judge’s Attitude Toward Law Enforcement

Here’s an interesting factor: different judges have different attitudes toward law enforcement, and that can affect how they rule on motions to suppress. Some judges tend to side with law enforcement, especially if they believe the officers were acting in good faith or if they think the violation of rights wasn’t significant. Other judges may take a more hardline approach when it comes to protecting constitutional rights, especially if the violation is clear.

So, the judge’s perspective and their view on police conduct can play a significant role in how often a motion to suppress is successful.

5. The Legal Precedents in the Jurisdiction

Where you’re located matters too. Different states and even federal courts have their own rules and precedents regarding the suppression of evidence. If there’s already a body of case law in a particular jurisdiction that supports suppression in cases of illegal searches, then the motion might stand a better chance. Conversely, if a jurisdiction is known for being lenient with law enforcement, motions to suppress might not get the same level of consideration.

Judges are bound by legal precedents, so a higher court’s decision on a similar issue can have a big impact on the outcome of your motion.

What Happens if the Motion to Suppress Is Successful?

If the motion to suppress is granted, it can have a huge impact on the case. The evidence that was obtained illegally will be excluded from the trial, and the prosecution won’t be able to use it to argue the defendant’s guilt. This could be a game-changer, especially if the evidence was crucial to the case.

In some situations, suppressing key evidence could lead to the charges being dropped or a plea deal being negotiated. Even if the case doesn’t get dropped, the suppression of critical evidence could make it much harder for the prosecution to prove their case.

That said, just because a motion is granted doesn’t mean the case is over. The prosecution might still have other evidence that’s not affected by the motion to suppress, and the case could continue. But one thing’s for sure: a successful motion to suppress gives the defendant a significant advantage.

Can a Motion to Suppress Be Filed in Every Case?

Technically speaking, yes—a motion to suppress can be filed in any criminal case where evidence was obtained through an unlawful search or seizure. But just because it can be filed doesn’t mean it will work in every case. Before filing a motion to suppress, it’s essential to evaluate whether there’s a strong legal basis for the claim. If there’s no valid reason to believe that the search violated your rights, the motion may be quickly dismissed.

The decision to file a motion should be made in consultation with an experienced attorney who can assess the specifics of the case and determine the best course of action.

Is It Worth Filing a Motion to Suppress?

Whether it’s worth filing a motion to suppress depends on the circumstances of your case. If there’s strong evidence that your constitutional rights were violated, filing a motion to suppress could be a powerful tool. It could result in the exclusion of critical evidence, which may lead to the dismissal of charges or a reduction in penalties.

However, if the motion is unlikely to succeed or if the evidence isn’t central to the case, it might be better to explore other defense strategies, like negotiating a plea deal or challenging the evidence in different ways.

Filing a motion to suppress does involve legal costs, time, and effort, so it’s important to weigh the potential benefits against the chances of success. Consulting with an experienced criminal defense attorney can help you understand if this is the right approach for your situation.

Conclusion

So, how often does a motion to suppress work? The truth is, motions to suppress are granted in only about 10% of cases, but that doesn’t mean they’re not worth considering. The success of a motion depends on factors like the specifics of the search or seizure, the strength of the legal argument, and the type of evidence involved.

Even though the odds aren’t always in your favor, a well-argued motion can be a game-changer in the right circumstances. If you believe that evidence against you was obtained illegally, talking to an experienced attorney is crucial. They can help you assess whether filing a motion to suppress is the right move for your case and guide you through the process.
