2025Under the second component of the IAC test, a defendant must prove prejudice “that is a ‘ “demonstrable reality,” not simply speculation.’ [Citations.] Prejudice requires ‘a reasonable probability that a more favorable outcome would have resulted …, i.e., a probability sufficient to undermine confidence in the outcome.’ ” (People v. Fairbank (1997) 16 Cal.4th 1223, 1241 .) “It is not enough for the defendant to show that the errors had some conceivable effect on the outcome of the proceeding.” ( Strickland, supra, 466 U.S. at p. 693–694, italics added; see Harrington, supra, 562 U.S. at p. 112

2016In order to establish a claim of IAC, defendant must demonstrate, “(1) counsel’s performance was deficient in that it fell below an objective standard of reasonableness under prevailing professional norms, and (2) counsel’s deficient representation prejudiced the defendant, i.e., there is a ‘reasonable probability’ that, but for counsel’s failings, defendant would have obtained a more favorable result.

2025“If the record on appeal sheds no light on why counsel acted or failed to act in the manner challenged,” the claim “must be rejected unless counsel was asked for an explanation and failed to provide one, or there simply could be no satisfactory explanation.” (People v. Carter (2005) 36 Cal.4th 1114, 1189 .) Defendant’s first IAC claim rests on the assumption the trial court ruled to allow, without restrictions, questioning the victim about currently hearing voices in her head.

2023Watson’s IAC and Evidence Code Section 352 Claims Fail for Lack of Prejudice Watson argues his IAC claim in both his direct appeal and his habeas petition and argues his Evidence Code section 352 claim in his direct appeal. 34 As we have discussed, to prevail on an IAC claim, a party must show that his counsel’s representation was unreasonable under “prevailing professional norms” and that, as a consequence, he was prejudiced. ( Strickland, supra, 466 U.S. at pp. 687–688, 692; Ledesma, supra, 43 Cal.3d at p. 216 .) Prejudice is established by demonstrating “a reasonable probability that, but f

2022In order to establish a claim of IAC, defendant must demonstrate, “(1) counsel’s performance was deficient in that it fell below an objective standard of reasonableness under prevailing professional norms, and (2) counsel’s deficient representation prejudiced the defendant, i.e., there is a ‘reasonable probability’ that, but for counsel’s failings, defendant would have obtained a more favorable result. [Citations.] A ‘reasonable probability’ is one that is enough to undermine confidence in the outcome.” (People v. Dennis (1998) 17 Cal.4th 468 , 540- 541, citing, among other cases, Strickland v

2019Under the plain language of section 1473.7 as amended, it is apparent that a defendant is no longer required to prove an IAC claim in order to have his or her convictions vacated and declared legally invalid: "A finding of legal invalidity may, but need not, include a finding of ineffective assistance of counsel." ( § 1473.7, subd. (a)(1).) Rather, a superior court is required to make a finding of legal invalidity if the defendant simply proves by a preponderance of the evidence a "prejudicial error damaging the moving party's ability to meaningfully understand , defend against, or knowingly a

2025Under the second component of the IAC test, a defendant must prove prejudice “that is a ‘ “demonstrable reality,” not simply speculation.’ [Citations.] Prejudice requires ‘a reasonable probability that a more favorable outcome would have resulted …, i.e., a probability sufficient to undermine confidence in the outcome.’ ” (People v. Fairbank (1997) 16 Cal.4th 1223, 1241 .) “It is not enough for the defendant to show that the errors had some conceivable effect on the outcome of the proceeding.” ( Strickland, supra, 466 U.S. at p. 693–694, italics added; see Harrington, supra, 562 U.S. at p. 112
