The Southern University Law Center overpaid employees by nearly $24,000 the past two years during international study abroad trips, according to a Louisiana legislative audit released Tuesday.

The overpayment, which did not receive state Division of Administration permission, was the only negative finding for the law school in the audit that received a ā€œCā€ letter grade.

The problem revolved around Southern following the U.S. State Department rates for travel, meals and lodging rather than the smaller Louisiana rates, without receiving proper state approval.

In a response letter, Southern Law Center Chancellor Freddie Pitcher Jr. said the school will, in the future, ensure that the proper steps for requesting state permission are followed.
