Misrepresenting the truth or altering it with "reluctance, inaccuracies or by silencing relevant facts or data" when appearing as a witness in a legal case is a crime. This is established by the Penal Code, which punishes this behavior with between six months and two years in prison, a penalty that can be increased to three years in prison if the lie is intended to harm the accused. However, the incrimination for false testimony is "exceptional" except in obvious cases or when there are clear indications that this false testimony has had effects on the procedure, jurists consulted by elDiario.es acknowledge. Judges tend to ignore statements to which they do not give credibility, but it is rare that they ask to investigate mendacious witnesses.
