Under what circumstance might a judge disallow evidence that is obtained legally?

A judge might disallow evidence that is obtained legally if it lacks probative value. Probative value refers to the ability of evidence to prove something pertinent to the case. If the evidence does not significantly contribute to proving a fact in the case or is not relevant to the issues being litigated, the judge may determine that it should not be admitted, despite being obtained through legal means.

Materiality is also important; if evidence is deemed not material, it may be disallowed, but this is not the primary issue concerning the legal justification for its inclusion. Contaminated evidence is a separate consideration that may also lead to disallowance but generally pertains more to how the evidence was handled rather than its legal obtainment. The phrase "low likelihood of disallowing" does not inherently point to a specific reason why evidence might be disallowed; therefore, it does not address the key concept of probative value, which is crucial in determining the admissibility of evidence in court.
