Credibility of Witnesses — Witness Who Has Pleaded Guilty to Same or Related Offense, Accomplices, Immunized Witnesses, Cooperating Witnesses (revised 2017) is a type of legal standard used to determine the credibility of a witness in a court of law. It takes into account the type of offense the witness has been charged with or has pleaded guilty to, the status of the witness as an accomplice or cooperator, and the protection or immunity they may receive. The first type of witness is a witness who has pleaded guilty to same or related offense. This type of witness has already been found guilty of the crime or an offense related to the one being tried in the court. The court must consider the potential bias the witness may have when testifying due to their own admission of guilt in the same or related offense. The second type of witness is an accomplice. This type of witness is someone who has been involved in the offense in some way, either as a participant or as an accessory. The court must consider the potential bias the witness may have due to their knowledge of the offense and their involvement. The third type of witness is an immunized witness. This type of witness has been given some form of protection or immunity from prosecution, such as a plea bargain or a grant of immunity from the prosecution. The court must consider the potential bias the witness may have due to their knowledge of the offense and the protection they have received. The fourth type of witness is a cooperating witness. This type of witness is someone who has agreed to provide information or testimony to the prosecution in exchange for some form of benefit, such as a reduced sentence or leniency in sentencing. The court must consider the potential bias the witness may have due to their knowledge of the offense and the benefit they are receiving in exchange for their cooperation.
