From "Justice League: Paradise Lost: Part II (#1.9)"
Diana, princess of Themyscira, stand forth! As your mother, I am overjoyed that you have at last returned to us. But as your queen, I am obliged to uphold the laws of Themyscira, and in bringing these outsiders to our island, you have broken our most sacred law. This cannot be overlooked.
[holds up hand for silence
] Diana, I have no choice. It is with a heavy heart that I must exile you from Themyscira.
