“While ensuring that the allegations are properly put and responded to, the fact-finding hearing or other hearing can be an inquisitorial (or investigative) process, which at all times must protect the interests of all involved. At the fact-finding hearing or other hearing: each party can be asked to identify what questions they wish to ask of the other party, and to set out or confirm in sworn evidence their version of the disputed key facts; and the judge should be prepared where necessary and appropriate to conduct the questioning of the witnesses on behalf of the parties, focussing on the key issues in the case.”
