From the NACDL press release:
The ‘trial penalty’ refers to the substantial difference between the sentence offered in a plea offer prior to trial versus the sentence a defendant receives after trial. This penalty is now so severe and pervasive that it has virtually eliminated the constitutional right to a trial. To avoid the penalty, accused persons must surrender many other fundamental rights which are essential to a fair justice systemYou can access the entire report here.
This report is the product of more than two years of careful research and deliberation. In it, NACDL examines sentencing and other data underlying the fact that, after a 50 year decline, fewer than 3% of federal criminal cases result in a trial. With more than 97% of criminal cases being resolved by plea in a constitutional system predicated upon the Sixth Amendment right to a trial, the fact of imbalance and injustice in the system is self-evident. The report identifies and exposes the underlying causes of the decline of the federal criminal trial and puts forth meaningful, achievable principles and recommendations to address this crisis. With its release, NACDL intends to launch a sustained effort to rein in the abuse of the trial penalty throughout federal and state criminal justice systems. The Trial Penalty report, and the principles and recommendations it puts forward, seeks to save the right to a trial from extinction.
