Is there a reasonable probability that the defense would have disclosed impeached impeached or impeached evidence to the defense?

disclosed to the defense, the result of the trial would have been different. [Citation.] Such a reasonable probability exists where the undisclosed evidence 'could reasonably be taken to put the whole case in such a different light as to undermine confidence in the verdict.' [Citations.] Impeachment evidence, as well as exculpatory evidence, falls within the scope of Brady. [Citation.]" (Eulloqui v. Superior Court (2010) 181 Cal.App.4th 1055, 1063.)
