When the defendants in a decades long land dispute in India officially asserted in court that their land had been given to them by their gods, the trial judge decided that he’d play along and require that the gods themselves attest to this claim. Hilarity ensued.
What also ensued is a brief but telling look into what a legal system based on the admission of untestable religious claims into evidence might look like. You can claim all you want that legal procedures are based on religious notions or premised on religious teachings. In practice, however, those notions seem nigh useless when it comes to resolving actual disputes.
