Jansen v The State

The appellants, Denise Cindy-Lee Jansen and Marco Rudolf Barnard, were charged in the Gauteng Division of the High Court, Pretoria, arising from sustained abuse of Jansen’s minor children, which resulted in the death of five-year-old Anthony Jansen. The parties concluded plea and sentence agreements under s 105A of the Criminal Procedure Act 51 of 1977. Jansen pleaded guilty to murder and child abuse, with an agreed effective sentence of 18 years’ imprisonment. Barnard pleaded guilty to culpable homicide, with an agreed sentence of 12 years’ imprisonment conditionally suspended for five years. The trial court convicted both appellants in accordance with the agreements but, without informing the parties that it regarded the agreed sentences as unjust, imposed materially different sentences.

The appeal was upheld. The convictions and sentences were set aside, and the matter was remitted to the Gauteng Division of the High Court, Pretoria, for a trial de novo before a different judge.

The case is a leading authority on the proper application of s 105A of the Criminal Procedure Act. It confirms that courts are not at liberty to unilaterally depart from plea and sentence agreements without strictly complying with the statutory safeguards. The judgment reinforces procedural fairness in plea bargaining and protects the accused’s right to make an informed election, while promoting transparency and legitimacy in the criminal justice system.
