Is a trial court's failure to strike a prior conviction allegation subject to review under the deferential abuse of discretion standard?

The trial court's "failure to . . . strike a prior [felony] conviction allegation is subject to review under the deferential abuse of discretion standard." (People v. Carmony (2004) 33 Cal.4th 367, 374.) "[A] trial court will only abuse its discretion in failing to strike a prior felony conviction allegation in limited circumstances. For example, an abuse of discretion occurs where the trial court was not `aware of its discretion' to dismiss [citation], or where the court considered impermissible factors in declining to dismiss [citation]." (Id. at p. 378.) In reviewing for abuse of discretion, we are "guided by two fundamental precepts. First, `"[t]he burden is on the party attacking the sentence to clearly show that the sentencing decision was irrational or arbitrary. [Citation.] In the absence of such a showing, the trial court is presumed to have acted to achieve legitimate sentencing objectives, and its discretionary determination to impose a particular sentence will not be set aside on review."' [Citations.] Second, a `"decision will not be reversed merely because reasonable people might disagree. `An appellate tribunal is neither authorized nor warranted in substituting its judgment for the judgment of the trial judge.'"' [Citation.] Taken together, these precepts establish that a trial court does not abuse its discretion unless its decision is so irrational or arbitrary that no reasonable person could agree with it." (Id. at pp. 376-377.)
