Meaning
Evidence gaps allow a fact finder to conclude that missing evidence would have been unfavorable to the party responsible for its loss. When a party fails to produce records during discovery, judicial adverse inference permits the court to assume the content of those records supported the opposing side’s claims. This rule applies only when the party had a duty to preserve the information and failed to do so with a culpable state of mind.
Evidentiary Weight
The presence of a gap in the record becomes a piece of evidence in its own right. If a founder deletes emails after a dispute begins, judicial adverse inference can lead to a ruling against them even if the emails were actually neutral. The burden shifts to the person who lost the data to explain why the loss was accidental rather than intentional.
Preservation Strategy
Rigorous data retention policies prevent the accidental trigger of this legal penalty. By maintaining a clear history of automated deletion schedules, a company can prove that a record was destroyed as part of a standard business process. This defense blocks the path for a claimant to argue that judicial adverse inference should apply to the missing data.
Litigation Outcome
Judges use this tool to restore the balance of a case when one side has been disadvantaged by the destruction of proof.
