What is the case law on whether prior conduct involving moral turpitude is not a criminal offence for impeachment purposes?

People v. Mansfield (1988) 200 Cal.App.3d 82, 87-88 [simple battery is not a crime of moral turpitude admissible for impeachment purposes].) But even if the evidence was relevant to their credibility as conduct involving moral turpitude, we conclude the trial court acted well within its discretion in excluding the evidence on the ground that its probative value, if any, was substantially outweighed by the probability its admission would necessitate undue consumption of time, confuse the issues, and mislead the jury. (See People v. Clark (2011) 52 Cal.4th 856, 931 [trial court has discretion under section 352 to exclude prior conduct involving moral turpitude].)
