A more thorough explanation:

Definition: Ex officio information is a type of criminal information that is filed by the attorney general on behalf of the Crown in the Court of King's Bench. This type of information is used for offenses that more immediately affect the government, as opposed to other types of informations where the Crown is the nominal prosecutor.

Example: If a person is suspected of committing a crime that directly affects the government, such as treason or espionage, the attorney general may file an ex officio information on behalf of the Crown. This type of information is used to ensure that justice is served and that the government is protected from harm.

Explanation: The example illustrates how an ex officio information is used in cases where the government is directly affected by a crime. The attorney general files this type of information to ensure that the Crown is represented in court and that the offender is held accountable for their actions. This type of information is important for maintaining the integrity of the government and protecting it from harm.
