S.231(4) is unconstitutional in its entirety and "cannot be severed into good and bad parts".
In addition to the reasons given in Kruger, s. 231(4) is in breach of s. 8 of the Charter to the extent that it does not comply with the following criteria: (1) there must be an independent arbiter (such as a judge, but not the Minister) who is satisfied that there are reasonable grounds for believing that an offence has been committed; (2) the Minister must present to the arbiter or judge grounds to believe that evidence is likely to be found at the place of search; (3) there must be statutory direction as to what is to be issued by the judge in granting his approval; and (4) the authorization must specify the things to be searched for.
