(1) Failure to comply with the provisions of this chapter shall not be grounds for a continuance nor shall it affect the validity of a jury verdict unless the party requesting the continuance or claiming invalidity has made timely objection and unless the party demonstrates actual prejudice to his cause and unless the noncompliance is substantial. An objection made at the day of a scheduled trial shall not be considered timely unless the objection, with the exercise of reasonable diligence, could not have been made at an earlier time.

    (2) If a data processing error occurs, that error shall not constitute grounds for questioning the entire list selected but only the specific person affected.
