Administrative due process over substantive due process

In Ledesma v. Court of Appeals, it elaborated on the well established doctrine of due process in administrative proceedings as follows:

Due process, as a constitutional precept, does not always and in all situations require a trial-type proceeding. Due process is satisfied when a person is notified of the charge against him and given an opportunity to explain or defend himself. In administrative proceedings, the filing of charges and giving reasonable opportunity for the person so charged to answer the accusations against him constitute the minimum requirements of due process. The essence of due process is simply to be heard, or as applied to administrative proceedings, an opportunity to explain one’s side, or an opportunity to seek a reconsideration of the action or ruling complained of.
