What causes wrongful convictions? Lies, mistaken eyewitnesses top the list.

Researchers examined 873 wrongful convictions and found that perjury or false accusations were responsible for more than half. New report offers insight into what leads to miscarriages of justice.

False accusations, official misconduct, and mistaken eyewitness identity are the primary reasons behind hundreds of wrongful convictions nationwide over the past 23 years, legal researchers conclude in a new report.

The report, released Sunday, is part of a database compiled by the University of Michigan and Northwestern University law schools that for the first time tries to pinpoint the problem of flawed judicial outcomes in state and federal courts. 

Researchers identified 873 wrongful convictions between January 1989 and March 2012; 46 percent of the cases examined were homicides, 35 percent were sexual assaults, and the remainder were other crimes. Half involved African-Americans, 38 percent whites, and 11 percent Latinos. The report concluded that perjury or false accusations were responsible for just over half of the failures, followed by mistaken eyewitness identification, official misconduct, false or misleading evidence, or false confession.

The number is tiny compared with the hundreds of millions of criminal cases handled over the same period, says Samuel Gross, a University of Michigan law professor and lead author. The figure is based on formal decisions by courts or executive officers; the majority of the wrongful convictions were cleared without the use of DNA evidence.

“These are the ones we know about. They don’t give us any direct measure of how common false convictions are across the system,” Mr. Gross says. “They just give us a sense of the ones that have come to light.”
