Is a defendant's failure to object to the section 1203.7.1 fee imposed by the probation department in violation of the California Probation Act?

^7. Defendant suggests, mainly in a heading preceding discussion of the section 1203.1 fee, that the section 1203.1 fee was imposed in violation of the statute's requirements that the probation officer determine a defendant's ability to pay. Defendant does not develop this claim and appears to acknowledge that the probation department recommended imposition of the fee after reviewing his work history and income sources. Lack of clear argument supporting a statutory violation claim forfeits its review on appeal. (Paterno v. State of California (1999) 74 Cal.App.4th 68, 106.) In any event, to the extent defendant is claiming a statutory violation, defendant's failure to object to the fee waives the claim on appeal. (People v. Valtakis (2003) 105 Cal.App.4th 1066, 1071-1072, 1075.)
