The Canadian Charter of Rights and Freedoms was enacted in 1982 as part of the repatriation of our Constitution. Prior to that citizens had no constitutional rights of privacy or freedoms and the final appeal in criminal cases was to the Privy Council in England. In 1982 we became masters of our own laws. At that time there existed Writs of Assistance which was a special type of search warrant issued to a police officer for his or her lifetime. No judicial decision was necessary. Under this Writ the officer could order citizens to do whatever the officer wanted to assist him in the execution of his or her duties and use whatever physical force considered necessary. The officer had unlimited power unrestricted as to date, time or place to enter any premises the officer wished to. Damaged or destroyed property did hot have to be repaired or destroyed. The Charter changed this.
