Educating Jurors about Forensic Evidence: Using an Expert Witness and Judicial Instructions to Mitigate the Impact of Invalid Forensic Science Testimony

Invalid expert witness testimony that overstated the precision and accuracy of forensic science procedures has been highlighted as a common factor in many wrongful conviction cases. This study assessed the ability of an opposing expert witness and judicial instructions to mitigate the impact of invalid forensic science testimony. Participants (N = 155) acted as mock jurors in a sexual assault trial that contained both invalid forensic testimony regarding hair comparison evidence, and countering testimony from either a defense expert witness or judicial instructions. Results showed that the defense expert witness was successful in educating jurors regarding limitations in the initial expert's conclusions, leading to a greater number of not-guilty verdicts. The judicial instructions were shown to have no impact on verdict decisions. These findings suggest that providing opposing expert witnesses may be an effective safeguard against invalid forensic testimony in criminal trials.     

The adequacy of China's responses to wrongful convictions

This paper examines a series of reforms that followed the discovery of high-profile wrongful convictions in China since 2005. There have been two waves of criminal justice reforms to prevent future wrongful convictions and to improve China's criminal justice system more generally. But it will be suggested in this paper that China's responses are inadequate because they allow traditional police and judicial practices that will lead to future wrongful convictions to continue. Further reforms will be suggested. First, police interrogations should be fully recorded, and the entire recording should be played back at trial. Second, the role of the defense counsel should be expanded. The use of state secrets as evidence against the accused should be curtailed. The close cooperation between the police, procuratorates and judiciary in the criminal justice should be counteracted by the creation of an independent body to review all serious convictions. Finally, the Chinese criminal justice has proven itself not safe enough to allow the broad use of capital punishment as a punishment for non-violent offences and at the very least, the immediate execution of prisoners who lose their final appeal must be abolished.     

Case rethinking: a protocol for reviewing criminal investigations

Mistakes in decision-making have been identified as the most common type of error in police investigations. Consequently, wrongful convictions and other types of criminal investigative failure may require a complete case ‘rethinking,’ particularly when new evidence disrupts the existing theory. A rush to judgment resulting in a premature shift from an evidence-based to a suspect-based investigation can produce a number of problematic thinking errors. Faulty assumptions, tunnel vision, groupthink, and other cognitive biases and organizational traps hinder evidentiary interpretation and evaluation. This article outlines a protocol for reviewing evidence and rethinking a wrongful conviction or unsolved crime when the existing investigative theory appears to be incorrect. The protocol involves four stages: (1) evidence; (2) interpretation; (3) patterns; and (4) analysis.     

Contractualism and the Death Penalty

It is a truism that there are erroneous convictions in criminal trials. Recent legal findings show that 3.3% to 5% of all convictions in capital rape-murder cases in the U.S. in the 1980s were erroneous convictions. Given this fact, what normative conclusions can be drawn? First, the article argues that a moderately revised version of Scanlon’s contractualism offers an attractive moral vision that is different from utilitarianism or other consequentialist theories, or from purely deontological theories. It then brings this version of Scanlonian contractualism to bear on the question of whether the death penalty, life imprisonment, long sentences, or shorter sentences can be justified, given that there is a non-negligible rate of erroneous conviction. Contractualism holds that a permissible act must be justifiable to everyone affected by it. Yet, given the non-negligible rate of erroneous conviction, it is unjustifiable to mete out the death penalty, because such a punishment is not justifiable to innocent murder convicts. It is further argued that life imprisonment will probably not be justified (unless lowering the sentence to a long sentence will drastically increase the murder rate). However, whether this line of argument could be further extended would depend on the impact of lowering sentences on communal security.

Judicial alignment and criminal justice: evidence from Russian courts

This paper investigates the effect of informal ties between judges (as represented by regional court chairpersons) and prosecutors on the repressive implementation of criminal justice in Russia in the area of fraud convictions. The authors utilize criminal law statistics of Russian regional courts for 2006–2010 to determine the alignment between chairpersons and prosecutors by measuring the length of their mutual career paths. The informal ties have a strong impact on trial outcome, which, however, changes over time. During periods of high bureaucratic risks and uncertainty, regions with a higher extent of informal ties between judges and prosecutors exhibit more repressive law enforcement. If external risks decrease, informal coalitions seem to increase the independence of the courts, insulating them from bureaucratic pressures and limiting their repressiveness.
