Introduction

The criminal justice system relies on evidence to establish guilt or innocence. However, not all evidence is created equal, and sometimes it may be necessary to get specific information thrown out in court. This article will discuss five ways that defense attorneys use to successfully argue for the exclusion of evidence during a trial.

1. Proving Illegal Search and Seizure

The Fourth Amendment protects citizens from unreasonable searches and seizures. If law enforcement officers obtain evidence through illegal search and seizure methods, such as when they don’t have a warrant or conduct a warrantless search without probable cause, this evidence may be suppressed. Defense attorneys can submit a motion to suppress this evidence before the trial begins, arguing that any findings from the illegal search should not be considered by the jury.

2. Establishing Chain of Custody Issues

For evidence to be admissible in court, there must be a clear chain of custody documenting how the evidence was handled from the time it was obtained until its presentation in court. If there are any gaps or inconsistencies in this chain of custody, defense attorneys can argue that the integrity of the evidence has been compromised and request that it be excluded from the trial.

3. Challenging Expert Witness Credibility

Expert witnesses are often called upon to testify about specific aspects related to a case. However, if their qualifications or credibility are called into question, their testimony may be considered irrelevant or biased. Defense attorneys may challenge an expert’s qualifications by questioning their educational background, professional experience, or even potential conflicts of interest. If successful, this may lead to the exclusion of their testimony from the trial.

4. Exclusion Based on Hearsay Rule

Hearsay is any out-of-court statement used in court to prove the truth of what was said during the statement. In general, hearsay is considered unreliable and therefore inadmissible as evidence during a trial. If a piece of evidence is based on hearsay, defense attorneys can argue for its exclusion from the trial. However, there are numerous exceptions to the hearsay rule, so it’s essential for defense attorneys to carefully examine the rules when determining if specific evidence falls under the hearsay category.

5. Arguing that Evidence is Irrelevant or Prejudicial

For evidence to be admissible, it must be relevant, meaning it has some bearing on the issue at hand in the case. Defense attorneys can argue that specific evidence should be excluded if they believe it’s irrelevant or has no probative value to the case. Additionally, if a piece of evidence is deemed more prejudicial than probative (causing unnecessary harm to the defendant without adding any substantial value), it can also be excluded from the trial.

Conclusion

Successfully getting evidence thrown out of court can dramatically change the course of a trial and increase the likelihood of an acquittal or reduced charges for a defendant. It’s crucial for defense attorneys to thoroughly review all aspects of a case and use these strategies when building a compelling defense for their client in the courtroom.
