The so-called Cannibal Cop is asking for a new trial.
Gilberto Valle was set to be sentenced Wednesday on his conviction for conspiring to kidnap, cook, and eat more than 100 women.
His sentencing has now been postponed indefinitely because his lawyers have filed papers asking that his conviction be thrown out.
They argue that his only crime is having deviant fantasies about women.
Valle had faced life in prison at his sentencing.
