William J. Brennan, Jr., Blount v. Rizzi — Opinion of the Court
“ One Senate Report expressed misgivings when the Postmaster General had originally sought the impounding power: 'The committee recognizes that even in its present form the bill gives the Postmaster General extraordinary and summary powers to impose a substantial penalty by impounding a person's mail for up to 20 days in advance of any hearing or any review by the courts. Such power is directly contrary to the letter and spirit of normal due process, as exemplified by the Administrative Procedure Act, which requires a hearing before any penalty may be imposed. ”
