The Alberta Crown Prosecution Service (ACPS) is the provincial agency responsible for prosecuting criminal cases in Alberta on behalf of the Crown (the government). Crown prosecutors review charges laid by police, decide whether there is enough evidence to proceed to trial, and present cases in court. They represent the public interest, not individual victims, though they work to achieve justice for all parties. The ACPS handles cases ranging from minor offences to serious crimes like murder, operating independently from political influence to ensure fair application of the law.
