Legal Definitions - Berry rule

The Berry rule is a legal standard used by courts to determine whether a defendant in a criminal case should be granted a new trial based on evidence that was discovered *after* their original trial. To successfully argue for a new trial under this rule, the defendant must demonstrate four key points:

• The evidence is genuinely new: The defendant and their legal team were unaware of this evidence at the time of the original trial. It must be truly "newly discovered."
• The evidence is significant: It must be crucial to the case, not just additional information that repeats what was already presented, or merely serves to question a witness's credibility without adding new, substantive facts.
• The evidence would likely change the outcome: There must be a strong probability that if this new evidence had been presented at the original trial, the jury would have reached a "not guilty" verdict.
• The evidence was not overlooked due to negligence: The defendant and their legal team must show they made reasonable efforts to find all relevant evidence before and during the original trial, and that the failure to discover this new evidence earlier was not due to a lack of diligence on their part.

Here are some examples illustrating how the Berry rule might apply:

• Example 1: Mistaken Identity in a Robbery Case

  A defendant, Mr. Henderson, was convicted of bank robbery based primarily on eyewitness testimony. Months after his conviction, a previously unknown security camera from an adjacent business, which had been obscured by overgrown foliage and was not initially reviewed by investigators, is discovered. The footage from this camera clearly shows a different individual, not Mr. Henderson, fleeing the scene of the robbery. Mr. Henderson's legal team could seek a new trial under the Berry rule.

  • This evidence is genuinely new because the camera footage was unknown and unreviewed at the time of the original trial.
  • It is significant because it directly contradicts the eyewitness identification and points to another perpetrator, rather than just adding minor details.
  • It would likely change the outcome, as clear video evidence of another person committing the crime would strongly suggest Mr. Henderson's innocence.
  • The failure to discover it earlier was not due to a lack of diligence, as the camera was obscured and not part of the initial investigation scope.

• Example 2: A New Alibi Witness in an Assault Case

  Ms. Chen was convicted of assault. Her defense at trial was that she was out of state, but she lacked definitive proof. After her conviction, a distant relative, who had been traveling abroad and was unreachable during the trial, returns to the country. This relative possesses dated and verifiable travel documents, hotel receipts, and photos with timestamps that irrefutably place Ms. Chen with them in another country at the exact time of the assault. Ms. Chen's attorney could file for a new trial.

  • The relative's testimony and supporting documents constitute genuinely new evidence because the relative was unavailable and unknown to the defense during the trial.
  • This evidence is significant as it provides a concrete and verifiable alibi, which is crucial to Ms. Chen's defense.
  • It would likely change the outcome because a strong, verifiable alibi would make a "not guilty" verdict highly probable.
  • Ms. Chen and her legal team demonstrated diligence by attempting to establish an alibi, but the specific witness and their proof were genuinely beyond their reach at the time.

• Example 3: Advanced Forensic Evidence in a Homicide Case

  Mr. Davis was convicted of homicide based on circumstantial evidence and a partial fingerprint. Years later, new advancements in forensic technology allow for a more comprehensive analysis of a tiny, previously unidentifiable fiber found at the crime scene. This new analysis reveals the fiber belongs to a rare type of industrial fabric, and subsequent investigation links it directly to a known serial offender who was active in the area at the time and has since confessed to similar crimes, though not this specific one. Mr. Davis's legal team could petition for a new trial.

  • The results of the advanced forensic analysis are genuinely new because the technology to identify the fiber's origin did not exist or was not available at the time of the original trial.
  • This evidence is significant as it directly points to another potential perpetrator and could exonerate Mr. Davis.
  • It would likely change the outcome, as strong forensic evidence linking another individual to the crime scene would cast significant doubt on Mr. Davis's guilt.
  • The failure to discover this link earlier was not due to a lack of diligence, as the necessary technology and investigative leads were not available at the time of the original trial.
