A former St James Christian Brothers' College student turned Satanist has launched a Supreme Court bid this week to have Satanism taught in religious instruction classes in Queensland state schools. Solicitor Trevor Bell, 54, is fighting on behalf of the Noosa Temple of Satan, which claims it was unlawfully barred from state schools earlier this year by Peter Kelly, the deputy-director general of state schools. The case has lifted the lid on the bizarre and disturbing world of black masses and devil worship by Satanists, who announced they will also support Premier Annastacia Palaszczuk's mercy killing laws. Bell said the Temple of Satan was seeking a judicial review of the department's ban. A hearing was set for July.
