Well you don't really need to define it, you need to understand how to apply the dot point. It's looking at how discretion operates in judicial procedures.
Basically judicial discretion is the power of the judge to make decisions on some matters without being bound by precedent or strict rules established by statutes.
Discretion looks at how personnel involved in the criminal process...judges, police, lawyers etc make decisions.
In reference to your dot point, what your looking at here is sentencing discretion. When a judge or magistrate sentences offenders he/she has to use his/her discretion...basically their sense and see whether or not they are going to follow or apply judicial guidelines, mandatory sentencing, maximum penalties, and this is up to them...basically discretion.
Judges and magistrates have different attitudes towards the various objectives of sentencing and this is reflected in their practice when imposing sentences. The sentencing decision is complicated and a number of factors must be taken into account. These factors include the maximum penalty, guideline judgments and mitigating and aggravating factors.
Guideline judgments outline how the tasks of sentencing for specified offences and circumstances should be approached. Guidelines are intended to be indications only and not intended to be applied to every case as if they were binding. It is up to the magistrate or judge whether they use guidelines as restricting mechanism or simply as a tool to structure discretion.
