"It is expected that pupils should understand that while different people may hold different views about what is right and wrong, all people living in England are subject to its law. The school ethos and teaching, which schools should make parents aware of, should support the rule of English civil and criminal law and schools should not teach anything that undermines it. If schools teach about religious law, particular care should be taken to explore the relationship between state and religious law. Pupils should be made aware of the difference between the law of the land and religious law."
