Horace Mann,
Slavery: letters and speeches
(1851)
“ The power of a commissioner, therefore, is judicial in the highest sense,—in the sense of the constitution. His decision cannot be reheard or reëxamined by any judge, or by any court, of any state, or of the United States. In no other case can a commissioner perform any judicial act, or issue any executive order, whose validity may not be reëxamined in the court for which he acts, or in some other. He cannot strike a blow, nor fine a dollar, nor punish by imprisonment for an hour. ”
