William O. Douglas,
Bailey v. Central Vermont Railway…
“ While a litigant has no constitutional right of appellate review, Congress has seen fit to grant it. And, until 1891, this court was, with negligible exceptions, the only instrument of such review. The increasing volume of our appellate work bade fair to render the court incompetent to give needed consideration to important cases which the public interest required that it decide. To preserve the privilege of appellate review, and to provide an appellate tribunal where most federal litigation should end without resort of this court, Congress created the Circuit Courts of Appeals. ”
