A top German court ordered a cannibal to be retried Friday, saying his manslaughter conviction for killing and eating a willing victim was too lenient.

“The conviction only for manslaughter and not for murder does not stand up to legal review,” the Federal Court of Justice said in a statement, upholding an appeal by prosecutors.

Armin Meiwes, 43, was sentenced to eight and a half years in January 2004 after a gory case that both fascinated and repulsed Germany and the world.

Meiwes admitted to killing a Berlin computer specialist, Bernd-Juergen B, he met via the Internet, but was spared a murder conviction as the victim had asked to be eaten in a startling case of sexual fetishism.

Prosecutors believed Meiwes should have been convicted of murder as he had killed to satisfy perverted desires. Meiwes’ lawyer urged the lesser “killing on request,” a form of illegal euthanasia that carries a maximum five year sentence.
