What is the standard of abuse of discretion in the appellate review of the denial of Romero motions?

(1999) 20 Cal.4th 490, 503.) This abuse of discretion standard also applies to appellate review of the denial of Romero motions. (People v. Carmony, supra, 33 Cal.4th at pp. 374-376.) It is the defendant's burden as the party attacking the sentencing decision to show that it was arbitrary or irrational, and, absent such showing, there is a presumption that the court " ' "acted to achieve the legitimate sentencing objectives, and its discretionary determination to impose a particular sentence will not be set aside on review." ' [Citations.]" (Id. at p. 377.) Such a discretionary decision " ' "will not be reversed merely because reasonable people might disagree." ' " (Ibid.)
