William O. Douglas,
Casey v. United States (343 U.S. 808…
“ Whatever action we take is a precedent.I cannot state too strongly my belief that if the courts are to retain their independence, they must decide cases taken on the merits. A confession of error by a litigant is, of course, an important factor to take into account in studying a record. [4] It may disclose an intervening decision on a question of law that undermines the lower court's conclusion; it may disclose perjury by an important witness or newly discovered evidence; it may disclose other factors which weaken the conclusion of the lower court. ”
