Sec. 2. Under a plan approved by the commissioners court of the county in the same manner as a plan is approved for jury selection under Section 62.011, Government Code, in a case other than a capital felony case, the court's designee may hear and determine an excuse offered for not serving as a juror, including any claim of an exemption or a lack of qualification. The court's designee may discharge the prospective juror or postpone the prospective juror's service to a date specified by the court's designee, as appropriate, if:
(1) the court's designee considers the excuse sufficient; and
(2) the juror submits to the court's designee a statement of the ground of the exemption or lack of qualification or other excuse.
