France’s top court on Tuesday confirmed that a probe into the shooting down of a presidential plane that triggered the 1994 Rwanda genocide should be closed.

This marks an end to a two-decade legal saga.

The Court of Cassation rejected the appeal by families of people killed in the missile attack on president Juvenal Habyarimana’s aircraft on April 6, 1994.

They had asked judges to reverse a lower court’s decision to abandon the case against people close to current President Paul Kagame.

“The investigation was complete and sufficient charges did not exist against anyone for committing the alleged crimes, nor any other infraction,” the Court of Cassation found.
