What is the test for reversal of a finding of misconduct in a criminal case?

Assuming the claim was properly preserved, the question becomes whether the prosecutorial misconduct was prejudicial, that is, whether it is reasonably probable a result more favorable to the defendant would have occurred if the prosecutor had refrained from the misconduct.⁴ (People v. Haskett (1982) 30 Cal.3d 841, 866.) Prosecutorial misconduct requires reversal under federal law unless the misconduct was harmless beyond a reasonable doubt. (People v. Cook (2006) 39 Cal.4th 566, 608.)
