A witness is a person who gives evidence at a hearing , either in person or in writing. They must have first-hand knowledge of the facts they are giving evidence about.
An expert witness is a person with specialised knowledge. They give evidence relevant to the case based on their expertise. The primary duty of an expert witness is owed to VCAT - not to their client.
At a hearing, the best way to give evidence is in person at the hearing.
Prepare questions in advance
You have the right to question the witnesses called by the other party so prepare a list of questions. After the witnesses are questioned, the applicant has an opportunity to clarify any matters raised.
When a witness cannot attend
If a witness cannot attend the hearing in person, they can give written evidence in an affidavit or statutory declaration. These documents must be completed truthfully, accurately and clearly. Sworn documents from a witness may not be as useful as the witness appearing in person because the other parties cannot question the person who made the document.
You may be able to summons a witness to appear if that person cannot or will not attend willingly.
A witness statement is a document that outlines the evidence a witness will give at a hearing. At the hearing, each witness is asked to ‘swear’ or to ‘solemnly affirm’ that their witness statement is true and correct.
How to prepare a witness statement
When you prepare a witness statement, you must:
- state your name, address and occupation at the beginning
- set out all the evidence you intend to give at the hearing in numbered paragraphs, in date order
- sign and date the document.
Give your witness statement to VCAT and the other party
Before the hearing, you need to send a copy of your witness statement to VCAT and give a copy to the other party. If you refer to documents in the witness statement, those documents also need to be shown to the other party before the hearing and submitted as evidence at the hearing.
See more about witness statements and other types of communication with VCAT and other parties.
Summons a witness
A summons is a legal document that says someone must produce documents or appear at VCAT on a certain date to give evidence.
Only summons a witness if that person is likely to be able to give evidence that is relevant to the case.
Before you apply for a summons, ask the person to provide the evidence or relevant documents. If the person refuses or is unable, you can apply to VCAT to issue a summons.
Apply for a summons
Any party to a proceeding can request a summons using the Summons to appear form. Other parties or the summonsed witness can object to the summons. We will decide if the witness must appear or produce documents.
Requesting an interstate summons
You can ask us for permission to summons someone outside Victoria. We can grant permission to serve a summons outside Victoria, by a VCAT order. The order must be signed by a judicial member of VCAT - that is, our president or vice president.
An expert witness is a person with specialised knowledge based on their training, study or experience.
VCAT may rely on the evidence from expert witnesses to form an opinion about a specialised or technical matter relevant to the case.
The expert’s opinion should be sound, complete, fair, unbiased and within the area of their expertise. The expert witness has a duty to VCAT to provide fair evidence, rather than to act as an advocate for the party who asked them to appear.
Expert witnesses must follow the procedures set out in the VCAT practice note on expert evidence: Practice Note PNVCAT2 - Expert Evidence.
If you are going to call an expert witness, you must make sure they are aware of the requirements set out in the practice note.
