Does a sentencing error in a federal civil case violate due process?

A sentencing error may violate due process if the state court misapplied its sentencing laws in an arbitrary or capricious manner. See Richmond v. Lewis, 506 U.S. 40, 50 (1992) ("[T]he federal, constitutional question is whether [the sentencing error] is so arbitrary or capricious as to constitute an independent due process . . . violation."). "Absent a showing of fundamental unfairness, a state court's misapplication of its own sentencing laws does not justify federal habeas relief." Christian v. Rhode, 41 F.3d 461, 469 (9th Cir. 1994). Nothing fundamentally unfair occurred here.
