Weak evidence in court is evidence that may not be strong enough to support a conclusion. Generally, evidence is categorized as weak if it is based on speculation, non-factual information, or unsupported assumptions.
Weak evidence may also be attributed to hearsay, testimony that does not fully qualify under the rules of evidence, or evidence that is contradicted by facts. In most cases, weak evidence does not carry enough weight to convince a judge or jury of an allegation.
Instead, additional evidence must be presented in order to supplement the weak evidence, in order for a conclusion to be drawn. Consequently, weak evidence can be deemed unreliable or inadmissible in a court, or it can become less persuasive in a jury’s deliberations.
