With no explanation, chose the best option from "A", "B", "C" or "D". and that the error was not fundamental. In Cagle v. State, 821 So.2d 443 (Fla. 2d DCA 2002), in which the State conceded error on appeal, this court clearly stated: A trial court may conduct probation revocation proceedings in an informal manner and it may question witnesses, but it may not assume the role of the prosecutor. Edwards v. State, 807 So.2d 762, 763 (Fla. 2d DCA 2002). Doing so deprives the defendant of the fair and impartial tribunal which is the cornerstone of due process. See Marshall v.

State, 740 So.2d 33 (Fla. 1st DCA 1999). Id. at 444; see also Lyles v. State, 742 So.2d 842 (Fla. 2d DCA 1999) (<HOLDING>). In the present case, the trial court assumed

C: holding that trial court committed fundamental error where it gave the appearance of partiality by taking sua sponte action which benefitted the state ie reopening the probation revocation hearing and ordering the probationer to submit to fingerprinting
D: holding lack of subjectmatter jurisdiction is fundamental error that this court may properly raise and recognize sua sponte
