Although uncommon these days, a "no decision" bout (ND) occurred when--by law or by pre-arrangement of the fighters--if both boxers were still standing at the bout's conclusion and there was no knockout, no decision was rendered and neither boxer was declared the winner.
There were two primary reasons for ND bouts: 1) some jurisdictions, in an attempt to curb gambling on the outcome of fights, enacted laws prohibiting decisions; and 2) some reigning boxing champions, in order to protect their titles, would demand in advance that a bout be "no decision" so that his opponent could not capture his crown by a win on points.
But this did not prevent the pool of ringside newspaper reporters from declaring a consensus result among themselves and printing a newspaper decision in their publications. Officially, however, a "no decision" bout results in neither boxer winning or losing.
Note: BoxRec.com Editors and other boxing historians sometimes use these unofficial newspaper decisions in compiling fight records for illustrative purposes only. These have a "NWS" designation in career records contained in the BoxRec database. Editors try to cite the specific newspapers giving their "decision."
