Attorney General Eric Holder Jr. this month issued new guidance to federal prosecutors in a memo that one U.S. Attorney said Thursday provides greater flexibility, and calls for more collaboration, in making charging decisions in criminal cases.

The Holder memo, which was submitted Wednesday to the U.S. Sentencing Commission for its hearing Thursday in Washington, D.C., says the “reasoned exercise of prosecutorial discretion is essential to the fair, effective, even-handed administration of the federal criminal laws.”
