A German appeals court ruled Tuesday that a former Nazi medic at the Auschwitz death camp was fit enough to be put on trial.
The court in Rostock overruled a lower court that said the 95-year-old defendant identified as Hubert Z. was too frail to withstand a trial.
The suspect served in Auschwitz from October 1943 until September 1944. He faces nearly 3,700 counts of being an accessory to murder.
While he is not directly charged with killing anyone, prosecutors say he was aware of the purpose of the death camp and "lent support to the organization."
Auschwitz, in southern Poland, was perhaps the most notorious camp in the Nazi death machine of World War II before Soviet forces liberated it in January 1945.
More than 1 million people were exterminated there. Most of the victims were Jews, but they also included Roma, prisoners of war and opponents of the Nazi regime.
