What is the burden of proving that counsel deliberately failed to object to a motion of motion?

affirmatively demonstrate "that counsel had '"'no rational tactical purpose'"' for [the] ... omission." (People v. Mickel, supra, 2 Cal.5th at p. 198.) This conclusion forecloses defendant's claim on direct appeal. Moreover, although defendant acknowledges he bears the burden of demonstrating prejudice on appeal and he advances a bare claim of prejudice, he makes no showing that counsel's failure to object resulted in prejudice in this case. As such, defendant satisfies neither prong of the inquiry.
