It may not be possible to know in advance of the proceedings in all circumstances whether an application should be made, and limiting such applications to before the start of a proceeding would be inconsistent with the approach taken in respect of other procedural provisions in current law that, if granted, enable a witness to testify with some form of accommodation. Reference can be made to section 486.1, testifying in the presence of a support person, or section 486.2, testifying via closed-circuit television.
