The Justice Department’s immigration courts have become less productive despite hiring more judges to handle deportation cases, according to a report released Thursday.

The report, issued by the DOJ’s inspector general (IG), found that the number of cases completed by the Executive Office of Immigration Review’s (EOIR) courts has decreased since 2006 despite the hiring of 27 additional judges

The EOIR has 59 immigration courts and 238 judges who decide which immigrants should be removed from the United States after the Department of Homeland Security (DHS) recommends deportation.

In fiscal 2006, the EOIR’s 211 judges completed 324,040 immigration cases. But in fiscal 2010, the courts’ 238 judges were only able to complete 287,207 out of the 325,326 cases they received, or about 88 percent, according to the IG’s investigation.
