What is the test for ineffective assistance in a motion for writ of habeas corpus?

To establish ineffective assistance, Roden must show that 1) his counsel's performance fell "below an objective standard of reasonableness," and that 2) there is "a reasonable probability that, but for counsel's errors, the result of the proceeding would have been different." (People v. Benavides (2005) 35 Cal.4th 69, 93.) "'Because the appellate record ordinarily does not show the reasons for defense counsel's actions or omissions, a claim of ineffective assistance of counsel should generally be made in a petition for writ of habeas corpus, not on appeal.'" (People v. Lucero (2000) 23 Cal.4th 692, 728-729.)
