It's my understanding that the provision is made for witnesses, including victims, and for prosecutors and judges to be able to apply for the imposition of measures to protect the security of a witness.
Existing Criminal Code provisions governing the application of testimonial aids and other measures designed to protect witnesses all provide for the possibility of a witness bringing an application, or for the prosecutor doing so on the witness' behalf.
This amendment would seek, it seems, to eliminate the possibility of witnesses making an application, which would be at odds with some other procedural provisions dealing with testimonial aids and the like; for example, those in which witnesses can make application or prosecutors can do so on behalf of a witness in respect of sections 486.1, testifying in the presence of a support person; 486.2, testifying via closed-circuit television; 486.3, restrictions on personal cross-examination; and 486.5, publication bans.
