What is the effect of section 1203.2a of the California Probation Code on a defendant who has been released from both confinement and parole?

3 Petitioner has sought dismissal of review on grounds of mootness, asserting he has now been released from both confinement and parole on his Marin County sentence. While the issue on which we granted review is thus "technically moot" in petitioner's case (see Butt v. State of California (1992) 4 Cal.4th 668, 677, fn. 7, 15 Cal.Rptr.2d 480, 842 P.2d 1240), we nonetheless exercise our discretion to address the issue, and therefore deny the dismissal request. Proper application of section 1203.2a is a recurring issue of public importance on which county probation officers and lower courts require practical guidance. (Butt v. State of California, supra, 4 Cal.4th at p. 677, fn. 7, 15 Cal.Rptr.2d 480, 842 P.2d 1240.)
