In a nutshell, every criminal case begins with an investigation and arrest by the police. After the arrest, if you are not released on a promise to appear in court, you are held for a bail hearing, where it is determined whether you should be released before trial, and on what terms.
After your bail hearing, we request the Crown disclosure, and review it with you. When disclosure is complete, we schedule a meeting with the Crown's office to negotiate for your charges to be withdrawn or reduced. Oftentimes, we also meet with the Crown and judge to discuss the legal issues in your case, such as outstanding disclosure, delay, the violation of your rights by police on arrest, unlawful searches by the police, and the admissibility of your statements to police.
If you wish to fight your criminal case at a trial, we will schedule trial dates. Oftentimes, we need to prepare pre-trial applications to deal with legal issues before trial, which are scheduled and argued before a judge. If you do not wish to have a trial but to resolve your criminal matter, we can hammer out the best deal possible with the Crown, and assist you in resolving the matter in court..
At trial, the Crown has the burden of proving their case. The Crown calls evidence, and you have the right to cross-examine the Crown's witnesses. You also have the right to call defence evidence, including through witnesses of your own. After the evidence is heard, the judge or jury make their decision, and, if you are convicted, there is a sentencing hearing to determine what punishment should be imposed.
After trial, you have the right to appeal, if you are unhappy with the result. You can appeal your conviction or sentence (or both). An appeal hearing is scheduled where you can argue that the judge or jury at your trial made an error of fact of law, that entitles you to a substituted decision (acquittal), new trial, or reduced sentence. You can also apply to remain on bail pending your appeal hearing.
If you are sentenced to imprisonment, there is a process for early release (parole), and once you are released from imprisonment. there is a process for applying for a pardon and to have your fingerprints and mugshot destroyed. This is the criminal justice process, in a nutshell.
