ABA Calls for moratorium on executions until death penalty fairness assured.
At its February 1997 mid-year meeting, the American Bar Association House of Delegates passed a resolution calling for a halt on executions until courts across the country can ensure that such cases are "administered fairly and impartially, in accordance with due process," and with minimum risk of executing innocent people.
The resolution was adopted by a margin of 280 to 119 votes. It cited some of the ABA's existing policies urging jurisdiction across the country to assure that people charged capital crimes receive due process protections. For example: provide competent counsel in capital punishment cases; eliminate race discrimination in capital sentencing; and prevent the execution of mentally retarded persons and persons who committed crimes as minors.
The resolution also said that the ABA takes no position on the death penalty per se.
