When a probationer violates the terms of his probation, does the probationer have to be sentenced or terminated by the trial court?

When a probationer has violated the terms of his or her probation, the trial court has discretion to revoke and terminate probation (and impose sentence) or reinstate probation. (People v. Bolian (2014) 231 Cal.App.4th 1415, 1420-1421; see 1203.2, subd. (a) [probation may be revoked "if the interests of justice so require" and the court has reason to believe the probationer has violated a probation condition].) We review for an abuse of discretion. (People v. Downey (2000) 82 Cal.App.4th 899, 909.)²
