What is the appropriate sentence for a defendant who has been convicted of a serious felony under section 667, subdivision (a)(1) of the California Criminal Code?

Where a person has been convicted of a serious felony in the current case, and it has been alleged and proved the person suffered a prior serious felony conviction within the meaning of section 667, subdivision (a)(1), the trial court must impose a consecutive five-year term for each such prior conviction that has been brought and tried separately. The trial court has no discretion in the matter; the imposition of such a term is mandatory. (People v. Valencia (1989) 207 Cal.App.3d at p. 1045, 255 Cal.Rptr. 180.)
