(a) to establish or rebut an allegation that unreasonable force was used to enable the procedure to be carried out; or
(b) to determine the admissibility of a confession or admission or other evidence adverse to the person where the person alleges that the evidence was induced or obtained by the use of unreasonable force; or
(c) to establish or rebut an allegation that the forensic procedure was not carried out in accordance with Division 6.
