The Danger of Opening the Door to Precluded Evidence
I recently served as an expert witness in a Post Conviction Relief case. The appellate attorney claimed that the trial attorney was ineffective for allowing previously banned evidence and testimony. This article is about that experience and my years of teaching Trial Advocacy and indigent defense.
When defending someone in a criminal trial, every decision matters. A defense attorney’s role is not only to present their client’s case but also to protect their client from prejudicial evidence that could unfairly sway the jury. Courts often exclude evidence before trial, deeming it irrelevant, overly prejudicial, or likely to confuse the issues. However, even when evidence is successfully precluded, a misstep during trial can undo those protections. This mistake—known as “opening the door”—can significantly harm a defendant’s case and even change the trial’s outcome.
As an experienced criminal defense attorney in Tucson, Arizona, I’ve seen firsthand the importance of navigating these complex evidentiary issues. At AJB Law Firm, I’ve built a reputation for effective trial advocacy and strategic defense, skills I honed through over 15 years of experience in criminal law and legal education. This post explores the dangers of opening the door to precluded evidence, how it happens, and what attorneys and clients can learn from these missteps.
What Does 'Opening the Door' Mean?
“Opening the door” is a legal concept that allows previously excluded evidence to be introduced at trial because of something said or done during the proceedings. For example, if a defense attorney makes an argument that contradicts or misrepresents the excluded evidence, the court may permit the prosecution to use that evidence to clarify the issue.
Pretrial evidentiary rulings are meant to protect defendants by keeping certain information out of the trial. This might include evidence that is irrelevant to the charges, overly prejudicial, or that risks confusing the jury. However, these protections can be lost if the defense inadvertently creates an opportunity for the prosecution to bring the excluded evidence back into play.
How This Happens
Opening the door often occurs when a defense attorney implies that no other evidence exists to support the prosecution’s case—despite knowing that it does. This approach might be an attempt to create doubt in the jury’s mind or bolster the defense’s argument. However, it can backfire in two significant ways:
Misleading the Jury: By suggesting the absence of additional evidence, the defense may inadvertently invite the court or prosecution to address the misleading implication. This often results in the introduction of the previously excluded evidence.
Erosion of Credibility: When the defense attorney’s argument is contradicted by evidence the jury wasn’t supposed to hear, it damages the defense’s overall credibility. This not only hurts the specific argument but can also lead the jury to question other aspects of the defense case.
Why Opening the Door is a Critical Error
Opening the door to precluded evidence can irreparably harm a defendant’s case. Courts exclude evidence for good reason—typically because its probative value (how useful it is in proving something) is outweighed by the potential for prejudice or confusion. When that evidence is reintroduced, it can paint the defendant in an unfairly negative light and undermine the jury’s ability to remain impartial.
For example, imagine a case where testimony about unrelated incidents is excluded because it could confuse the jury or make them assume guilt based on irrelevant details. If the defense implies that no such incidents occurred, the court may allow the prosecution to present that excluded testimony to correct the misleading impression. This not only weakens the defense’s argument but also shifts the jury’s focus to evidence they were never meant to hear.
Lessons for Attorneys
For defense attorneys, avoiding this pitfall requires a combination of preparation, strategic foresight, and respect for pretrial rulings. Here are some key takeaways:
Know the Boundaries: A thorough understanding of pretrial evidentiary rulings is essential. Attorneys must be vigilant about avoiding arguments or lines of questioning that could open the door to excluded evidence.
Anticipate Risks: Trial advocacy requires anticipating how the prosecution and court might respond to certain arguments. Attorneys should weigh the risks of making potentially misleading statements against the potential benefits.
Focus on Credibility: Misleading the jury—even inadvertently—can backfire. Defense attorneys should strive for arguments that are both persuasive and aligned with the known facts of the case.
Prepare Thoroughly: Understanding the case inside and out, including all pretrial rulings and the evidence that was excluded, is crucial to avoiding unintentional errors.
