An offence is a breach of law, a crime
An offender is someone who has committed a crime. The term offender is only used after a person has been convicted of an offence. Before conviction, someone facing a charge is called the accused.
Most criminal hearings are heard in open court where the public can attend. Some sensitive cases are heard in private, which is known as ‘in camera’.
Opinion A statement by a court or judge of reasons for the decision in a case. In the Sheriff Court it is called a "Note" and is attached to the interlocutor containing the decision.
Options hearing A hearing in an ordinary action in the sheriff court to decide the next stage in the case. That could be a continuation of the hearing for up to a month to adjust the pleadings, the fixing of a debate on the law or a proof of the facts.
Order for Lifelong RestrictionAn OLR is a lifelong sentence put in place to protect the public. It is a sentence of imprisonment which can be imposed on people convicted at the High Court of a serious violent offence (other than murder), a serious sexual offence, an offence which endangers life, or an offence which indicates a tendency to serious violent, sexual or life-endangering offending. The court must impose an OLR where it appears that, because of the nature or circumstances of the offence, there is a likelihood that the offender will in the future seriously endanger the lives, or physical or psychological well-being, of members of the public, if he or she is not in custody.
