The Obama administration is expanding the criteria to decide which prisoners jailed for drug crimes can obtain clemency. The Fair Sentencing Act of 2010 reduced sentencing disparities between users of crack cocaine and powdered cocaine to address a racial imbalance in prison terms. But the law did not apply retroactively. On Monday, Attorney General Eric Holder said the administration will announce new guidelines to help close the gap.

Attorney General Eric Holder: “There are still too many people in federal prison who were sentenced under the old regime and who, as a result, will have to spend far more time in prison than they would if sentenced today for exactly the same crime. This is simply not right. The White House has indicated it wants to consider additional clemency applications to restore a degree of justice, fairness and proportionality for deserving individuals who do not pose a threat to public safety. The Justice Department is committed to recommending as many qualified applicants as possible for reduced sentences.”

The new criteria could mean early parole for thousands of prisoners. Details of the new policy are expected on Thursday.
