What is the cumulative effect of errors in a jury trial?

Finally, defendant argues the cumulative effect of the errors undermines confidence in the outcome of the trial. "Under the cumulative error doctrine, the reviewing court must 'review each allegation and assess the cumulative effect of any errors to see if it is reasonably probable the jury would have reached a result more favorable to defendant in their absence.' [Citation.] When the cumulative effect of errors deprives the defendant of a fair trial and due process, reversal is required. [Citation.]" (People v. Williams (2009) 170 Cal.App.4th 587, 646.) However, having found no error, it is axiomatic we find no cumulative error.
