In People v. Pacchioli (1992) 9 Cal.App.4th 1331, the defendant asserted that it would be "fundamentally unfair" to allow his statements made during a probation interview after a guilty plea, which was later withdrawn, to be used against him. (Id. at p. 1338.) The appellate court determined that there was no denial of due process where a trial court ruled the defendant's voluntary statements to the probation officer during a post-plea, pre-sentence interview would be admissible for impeachment if the defendant chose to testify. (Id. at pp. 1339-1341.)
