A Bind Over is neither a conviction nor a punishment. It is a preventative measure whereby a person enters into a recognisance before the court (gives a promise) to engage in good behaviour and to keep the peace for a period not exceeding three years. The recognisance is a promise to pay a specified sum of money if the recognisance is breached.
The bind over specifies the conduct which must not be committed during the period of the bind over. Orders made for payment of all or part of the recognisance if the bind over is breached are similarly not criminal convictions.
