In a trial, the jury is selected at random from among the population. From the moment at which a person reaches legal age, and if you are selected, you are required to do jury duty, except in exceptional situations. Refusing or canceling your participation can lead to a prison sentence. Lawyers may refuse a certain number of selected jurors, and this is why the term « selection » is used. In one famous trial in Quebec, no one wanted to sit on the jury and all found excuses. Thus a court order was given to police officers to go and get the jury members off the street, from among the first people they met!
