(See link for footnotes.)

> Non-Judicial Proceedings.—A court proceeding is not a requisite of due process.745 Administrative and executive proceedings are not judicial, yet they may satisfy the Due Process Clause.746 Moreover, the Due Process Clause does not require de novo judicial review of the factual conclusions of state regulatory agencies,747 and may not require judicial review at all.748 Nor does the Fourteenth Amendment prohibit a state from conferring judicial functions upon non-judicial bodies, or from delegating powers to a court that are legislative in nature.749 Further, it is up to a state to determine to what extent its legislative, executive, and judicial powers should be kept distinct and separate.750

Fair. I sit enlightened. Although the court cases so far didn't seem to end up there.
