Abuse of discretion n.滥用自由裁量权，滥用酌处权
a polite way of saying a trial judge has made such a bad mistake （“clearly against reason and evidence” or against established law） during a trial or on ruling on a motion that a person did not get a fair trial. A court of appeals will use a finding of this abuse as a reason to reverse the trial court judgment. In criminal cases abuse of discretion can include sentences that are grossly too harsh. In a porce action， it includes awarding alimony way beyond the established formula or the spouse‘s or life partner’s realistic ability to pay.
