About
Jonathan Bach represented the defense on Day 12 during disputes over expert testimony and in examinations of Dr. Dawn Hughes and George Kaplan.
At an evidentiary hearing, Bach told the court that the defense was concerned that coercive-control testimony and a broad presentation of abusive conduct could exceed limits previously set for Hughes's testimony. He then cross-examined Hughes in multiple resumed segments that day.
Bach also participated in a hearing over an expert-bias training document. The court asked him to explain the basis for offering the document, later overruled an objection during his cross-examination, and described a sequence in which redirect could address a possible Rule 702 gap before Bach responded on recross.
After Kaplan's redirect, Bach conducted recross-examination. The proceedings reflect his role in testing expert testimony, litigating the scope and use of expert-related material, and preserving further examination on the issues raised.
