Why Has The DOJ Stopped Civilly Enforcing The FCPA?

The Foreign Corrupt Practices Act specifically authorizes the DOJ to civilly (not just criminally) enforce the statute against non-issuers.
Indeed, between 1991 and 2001 approximately 35% of all DOJ corporate FCPA enforcement actions were civil actions. However, the last time the DOJ invoked this express statutory remedy was in 2001 and the question is posed: why has the DOJ stopped civilly enforcing the FCPA?
Make sure to read to the end of the post to hear the DOJ’s non-responsive answer to this question.
Perhaps instead of creating new ways to enforce the FCPA not even mentioned in the statute (such as non-prosecution agreements, deferred prosecution agreements and most recently declinations with disgorgements) the DOJ should go back to enforcing the FCPA in ways expressly authorized by Congress.
