Tex. Tax Code § 6.037

In this title, a reference to the taxing units entitled to vote on the appointment of appraisal district board members includes the conservation and reclamation districts participating in the appraisal district, without regard to whether the conservation and reclamation districts are currently entitled to do so under Section 6.03(c). In a provision of this title other than Section 6.03 or 6.031 that grants authority to a majority or other number of the taxing units entitled to vote on the appointment of appraisal district directors, including the disapproval of the appraisal district budget under Section 6.06 and the disapproval of appraisal district board actions under Section 6.10, the conservation and reclamation districts participating in the appraisal district are given the vote or authority of one taxing unit. That vote or authority is considered exercised only if a majority of the conservation and reclamation districts take the same action to exercise that vote or authority. Otherwise, the conservation and reclamation districts are treated in the same manner as a single taxing unit that is entitled to act but does not take any action on the matter.
