The bidding process was suspended in the fall of 2010 due to lack of competition. Before bidding reopened in 2011, Maryland passed a law (at the request of Leo Bretholz and other Holocaust survivors) requiring Keolis's majority owner, SNCF (currently solely owned by the French government)  to fully disclose its role in transporting Jews to concentration camps during World War II (while SNCF was under control of the Nazi government), to the satisfaction of the Maryland state archivist, before Keolis would be allowed to place a bid for MARC service. Keolis faced similar issues while bidding for VRE operations in 2009, but in the end, they were allowed to run VRE.
