Getting off on a technicality is a term used when a defendant is acquitted of a crime due to a technical error or loophole in the legal system. There are various synonyms for this phrase, including walking free, escaping justice, dodging the bullet, and beating the rap. Other terms that can be used include getting a free pass, receiving a get-out-of-jail card, and slipping through the cracks. The use of these phrases implies that the defendant has not been completely exonerated and may have been guilty of the crime they were accused of, but they have managed to avoid the consequences due to a technicality.
