Some laws were pre-Christian in origin. These secular laws existed in parallel, and sometimes in conflict, with Church law. Although brehons usually dealt with legal cases, kings would have been able to deliver judgments also, but it is unclear how much they would have had to rely on brehons. Kings had their own brehons to deal with cases involving the king's own rights and to give him legal advice. Unlike other kingdoms in Europe, Gaelic kings—by their own authority—could not enact new laws as they wished and could not be "above the law". They could, however, enact temporary emergency laws. It was mainly through these emergency powers that the Church attempted to change Gaelic law.
