What is the current state and federal law on the grounds of prosecutorial misconduct?

"The applicable federal and state standards regarding prosecutorial misconduct are well established. '"A prosecutor's . . . intemperate behavior violates the federal Constitution when it comprises a pattern of conduct 'so egregious that it infects the trial with such unfairness as to make the conviction a denial of due process.'"' [Citations.] Conduct by a prosecutor that does not render a criminal trial fundamentally unfair is prosecutorial misconduct under state law only if it involves '"'the use of deceptive or reprehensible methods to attempt to persuade either the court or the jury.'"' [Citation.] As a general rule a defendant may not complain on appeal of prosecutorial misconduct unless in a timely fashionand on the same groundthe defendant made an assignment of misconduct and requested that the jury be admonished to disregard the impropriety. [Citation.]" (People v. Samayoa (1997) 15 Cal.4th 795, 841.)
