The New York Times reports:

Judges appointed by Republican presidents gave longer sentences to black defendants and shorter ones to women than judges appointed by Democrats, according to a new study that analyzed data on more than half a million defendants.

“Republican-appointed judges sentence black defendants to three more months than similar nonblacks and female defendants to two fewer months than similar males compared to Democratic-appointed judges,” the study found, adding, “These differences cannot be explained by other judge characteristics and grow substantially larger when judges are granted more discretion.”

The study was conducted by two professors at Harvard Law School, Alma Cohen and Crystal S. Yang. They examined the sentencing practices of about 1,400 federal trial judges over more than 15 years, relying on information from the Federal Judicial Center, the United States Sentencing Commission and the Transactional Records Access Clearinghouse at Syracuse University.

Douglas A. Berman, an authority on sentencing law at Ohio State University, said the study contained “amazing new empirical research.”

“It’s an extraordinarily important contribution to our statistical understanding of sentencing decision making in federal courts over the last two decades,” he said.

It has long been known that there is an overall racial sentencing gap, with judges of all political affiliations meting out longer sentences to black offenders. The new study confirmed this, finding that black defendants are sentenced to 4.8 months more than similar offenders of other races. [Continue reading…]
