Why Objecting to Expert Testimony is Crucial in Legal Defense
Navigating a legal trial as an accused individual can be daunting, particularly when expert testimony is involved. Expert witnesses bring specialized knowledge that can profoundly influence the jury’s perspective. Thus, it is crucial for trial lawyers to safeguard their client’s rights by critically evaluating and objecting to expert testimonies when necessary. This article highlights the significance of this practice, offering accused individuals insights into its role in ensuring fair trials.

Understanding the Significance of Expert Testimony in Legal Cases
Expert testimony can make or break a case. Such expert witnesses are called upon to shed light on technical or specialized aspects that go beyond the average person’s knowledge. Their insights often carry substantial weight, potentially tipping the scales of justice.
However, the reliance on expert testimony also opens the door to misunderstandings, misinterpretations, or even deliberate biases. After all, experts are human too, and their analyses or conclusions can be influenced by various factors. This is why scrutinizing their testimony is not just advisable; it’s indispensable.
The Importance of Objecting to Expert Testimony
Objecting to expert testimony is crucial for several reasons:
- Protecting the Rights of the Accused: An expert’s influence should never get in the way of the accused’s right to a fair trial. Objecting is a tool to ensure this balance, keeping the jury’s perspective grounded in objective truth rather than speculative science.
- Ensuring the Credibility of Evidence: Not all experts are created equal. Some may lack the necessary credentials or have conflicts of interest. By objecting, trial lawyers can force the court to re-evaluate the expert’s reliability and credentials, maintaining the integrity of the evidence presented.
- Upholding Fair Legal Standards: By challenging dubious expert claims, trial lawyers play a vital role in setting legal precedents that prioritize fairness and factual accuracy in courtrooms.
A Deep Dive into the Legal Process of Objecting to Expert Testimony
Objecting to expert testimony is a complex process that requires an understanding of legal grounds. Here are some critical steps and strategies involved:
Legal Grounds for Objection
- Qualifications: The trial lawyer can argue that the witness lacks the qualifications or expertise to provide a reliable opinion on the matters at hand.
- Relevance: If the testimony does not directly contribute to the issue being litigated, the trial lawyer can argue its irrelevance and push for its exclusion.
- Methodology: Trial lawyers must scrutinize the methods used by the expert to ensure they are scientifically valid and widely accepted within the relevant field.
- Bias: Evidence of the expert potentially having a stake in the case outcome can be grounds for challenging credibility.
The Objection Procedure
The objection must be timely and precise. Lawyers typically raise objections when experts begin straying beyond established facts or presenting speculative opinions. At this point, a trial lawyer will articulate their specific objections, referencing legal principles and precedents to back their case.
The Role of Cross-Examination
Beyond objections, cross-examination is another powerful tool. It allows trial lawyers to disagree with the expert’s testimony, expose weaknesses, and highlight contradictions, further educating the jury on the matter’s complexities.
People v. Corbi
For years, Freddy Rivera Corbi, the defendant, was subjected to bullying by gang members in his neighborhood. During the summer of 2019, he sustained significant injuries when a gang member stabbed him in the wrist with a broken beer bottle. A month later, Corbi encountered another gang member, Lazaro Orozco, which led to an altercation resulting in Corbi fatally shooting Orozco. The trial centered on whether the shooting was an act of self-defense, or if Corbi, being a member of a rival gang, killed Orozco out of revenge. Ultimately, the jury found Corbi guilty of second-degree murder. On appeal, Corbi contended that the trial court erred in permitting the prosecution’s gang expert to give opinions regarding the relevance of Corbi’s actions leading up to the shooting. The expert, Detective Hansel, suggested that Corbi followed Orozco because “something upset him” and instigated a confrontation by tracking him in his own gang’s territory. Corbi argued that these opinions were speculative, not useful to the jury, and encroached upon the jury’s role in determining whether he initiated the conflict.
The appeals court upheld this decision due to lack of prejudice. A person qualifies as an expert witness if they possess specialized knowledge, skills, experience, training, or education that makes them an expert on the relevant subject matter, as stipulated by Evidence Code, Section 720 (a). Nonetheless, an expert’s qualification does not grant them unlimited freedom to present opinions within their field of expertise. The trial court must reject expert views that are either speculative or lack utility for the jury. In this case, the court determined that the expert’s evaluation of Corbi based on hypothetical elements introduced by the prosecution was improper. While Detective Hansel’s conclusion that Corbi initiated a confrontation by tracking Orozco was logical, it was deemed unhelpful to the jury, as applying such logic did not require expert insights.
