No. Once the police are called in, the complainant loses control over the process. And just as police follow strict policies to lay charges in domestic cases, prosecutors are under strict policies to zealously pursue convictions to the full extent of the law. If a complainant tries to get the charges dropped, she will be sent to speak with a worker at the Victim Witness Assistance Program, which is an agency affiliated with the Crown. They will discourage her from trying to have the charges dropped. If she says that she exaggerated or lied to the police, she will be told that she risks being charged with public mischief. Even if she continues to insist on having the charges dropped, the Crown will likely proceed with the prosecution anyway.
