This is a court proceeding in Superior Court where the result of a bail hearing can be appealed. You can apply for a bail review if you are denied bail at your bail hearing. To succeed, you must show either a change in circumstances or an error of law by the justice of the peace who conducted your original bail hearing.
A change in circumstances is a big change in your life that makes your bail plan more suitable. For example, you may have an additional surety who is able to help supervise you.
