Inrng reports that Longo got off on a technicality (of course). Discrepancy between French law and the WADA/UCI guidelines.

The FFC followed guidelines set by the UCI and WADA over naming Longo in their “testing pool” of athletes who are subject to regular monitoring and surprise controls. Under the rules once an athlete is named, they are in this pool until further notice. It could mean a decade if they have a long career and in the case of Longo, the most evergreen of athletes, even longer.
But those are the rules and French law is different. An amendment to Article L.232-15 of the Code du Sport, 2010-379 on 14 avril 2010 requires a sports body in France to inform the athlete concerned that they are in the testing pool every year, to send a letter confirming their status. It seems the FFC did not do this, thus under the law Longo was not notified that she was in the pool. Therefore under the law Longo was no longer subject to the testing. She could not miss a test since she was no longer considered to be in the pool.
