Section 27. Offer of compromise not admissible. –

In civil cases, an offer of compromise is not an admission of any liability, and is not admissible in evidence against the offerror.

In criminal cases, except those involving quasi-offenses (criminal negligence) or those allowed by law to be compromised, an offer of compromise by the accused may be received in evidence as an implied admission of guilt. A plea of guilty later withdrawn, or an unaccepted offer of a plea of guilty to a lesser offense, is not admissible in evidence against the accused who made the plea or offer.

An offer to pay or the payment of medical, hospital or other expenses occasioned by an injury is not admissible in evidence as proof of civil or criminal liability for the injury. (24a)
