Crouch acreditava que Bagman estava trabalhando com os Comensais da Morte
Barty Crouch processou Bagman durante a Primeira Guerra Mágica por fornecer informações a Augustus Rookwood. Crouch era notoriamente draconiano e provavelmente acreditava que Bagman fosse culpado.
“Ludo Bagman, you have been brought here in front of the Council of Magical Law to answer charges relating to the activities of the Death Eaters,” said Mr. Crouch. “We have heard the evidence against you, and are about to reach our verdict. Do you have anything to add to your testimony before we pronounce judgment?”

Bagman, no entanto, provavelmente só foi enganado por um verdadeiro Comensal da Morte, Rookwood.
“But I’ve told you, I had no idea!” Bagman called earnestly over the crowd’s babble, his round blue eyes widening. “None at all! Old Rookwood was a friend of my dad’s . . . never crossed my mind he was in with You-Know-Who! I thought I was collecting information for our side! And Rookwood kept talking about getting me a job in the Ministry later on . . . once my Quidditch days are over, you know . . . I mean, I can’t keep getting hit by Bludgers for the rest of my life, can I?”

Crouch presumivelmente disse a Winky que Bagman estava trabalhando para Voldemort. Esta era provavelmente a informação que ela estava referenciando quando alegou que Bagman era "um feiticeiro malvado".
Crouch, sem dúvida, acreditava que qualquer um que ele processasse era culpado, e de fato havia presidido o julgamento de pelo menos um outro inocente, Sirius Black.“Despicable,” Mr. Crouch spat at Dumbledore, sitting down as Bagman walked out of the dungeon. “Rookwood get him a job indeed. . . . The day Ludo Bagman joins us will be a sad day indeed for the Ministry. . . .”
