In Henley v. Youngstown Bd. of Zoning Appeals, 90 Ohio St.3d 142, 2000 Ohio 493, 735 N.E.2d 433, the Ohio Supreme Court distinguished the standard of review to be applied by common pleas courts and appellate courts in R.C. Chapter 2506 administrative appeals. The Court stated: "The common pleas court considers the 'whole record,' including any new or additional evidence admitted under R.C. 2506.03, and determines whether the administrative order is unconstitutional, illegal, arbitrary, capricious, unreasonable, or unsupported by the preponderance of substantial, reliable, and probative evidence.
