In Proctor v. Andrews, 972 S.W.2d 729, 735 (Tex. 1998), the Court held that a delegation of authority to private entities to select "qualified neutral arbitrators" to hear civil service commission appeals provided adequate guidance. Proctor, 972 S.W.2d at 738. In that case, however, the assessment of qualifications was uniquely within the delegate's expertise, and the term "neutral" was sufficiently specific to reflect legislative intent. Moreover, in Proctor, the authority delegated was narrow -- to forward names of potential arbitrators for selection. The criteria "qualified" and "neutral" were well-suited for this narrow purpose. This contrasts starkly with the delegation here, in which the elastic standards "reasonably feasible and practical" provide little guidance to the landowners in exercising their relatively broad authority.
