What is the test for making a defendant pay restitution?

"The California Constitution gives crime victims a right to restitution and, consequently, requires a court to order a convicted wrongdoer to pay restitution in every case in which a crime victim suffers a loss. (Cal. Const., art. I, 28, subd. (b)(13)(B).) To implement this requirement, section 1202.4, subdivision (f), generally provides that 'in every case in which a victim has suffered economic loss as a result of the defendant's conduct, the court shall require that the defendant make restitution to the victim or victims in an amount established by court order, based on the amount of loss claimed by the victim or victims or any other showing to the court.' " (People v. Sy (2014) 223 Cal.App.4th 44, 62.) But section 1202.4 "limits restitution to losses caused by the criminal conduct for which the defendant was convicted." (People v. Lai (2006) 138 Cal.App.4th 1227, 1249.)
