What is the test for a motion for a new trial based on newly discovered evidence?

A court may grant a new trial "[w]hen new evidence is discovered material to the defendant, and which he could not, with reasonable diligence, have discovered and produced at the trial." ( 1181, subd. 8.) In ruling on a motion for new trial based on newly discovered evidence, the trial court considers whether: (1) the evidence, and not simply its materiality, is newly discovered; (2) the evidence is not merely cumulative; (3) the defendant in the exercise of reasonable diligence could not have discovered and produced the evidence at trial; (4) the newly discovered evidence is of such strength that a result more favorable to the defendant is probable if the new evidence is admitted on retrial; and (5) these facts are shown by the best evidence of which the case admits. (People v. Howard (2010) 51 Cal.4th 15, 43.) " 'In addition, "the trial court may consider the credibility as well as materiality of the evidence in its determination [of] whether introduction of the evidence in a new trial would render a different result reasonably probable." [Citation.]' " (Ibid.)
