● Yet a defendant has no constitutional right to plea bargain. No basic rights are infringed by trying him rather than accepting a plea of guilty; the prosecutor need not do so if he prefers to go to trial. Under the present Rules, the acceptance of an offer to plead guilty is not a demandable right but depends on the consent of the offended party and the prosecutor, which is a condition precedent to a valid plea of guilty to a lesser offense that is necessarily included in the offense charged. The reason for this is that the prosecutor has full control of the prosecution of criminal actions; his duty is to always prosecute the proper offense, not any lesser or graver one, based on what the evidence on hand can sustain (Estipona v. Lobrigo, G.R. No. 226679, August 15, 2017).
