How to change a complaint

A complainant must:

There are two kinds of changes to a complaint:

  1. Adding details about conduct in the complaint. The legal term is “particulars”.
  2. Adding new conduct that the complainant says is discrimination. This is called a “new allegation”.

You don’t need to apply if you want to add details about conduct in the complaint.

When a complainant must apply to change a complaint

Rule 24 of the Tribunal’s Rules of Practice and Procedure apply to amending a complaint.

You must apply to add a new allegation in three situations.

  1. The hearing is less than 4 months away
  2. The respondent applied to dismiss the complaint and the Tribunal has not decided the application
  3. The new allegation occurred outside the time limit for filing the complaint under s. 22 of the Human Rights Code

Legal test: change a complaint if the hearing is less than 4 months away

  • Participants need enough time to prepare for the hearing. You can add a new allegation if the hearing is more than 4 months away.
  • If not, you must show that changing the complaint will help get to a “just and timely resolution” of the complaint.
  • The Tribunal will consider the effect on the process and the outcome.
    • How will it affect the time to solve the complaint?
    • How much would it cost the other side?
    • Would it affect a participant’s ability to present their side?
    • Would it affect a participant’s chance to have a say about something important? For example, something that could affect the outcome of the complaint.
  • In the application, explain:
    • How is the change important?
    • Why didn’t you change the complaint earlier?
    • Will the change delay the hearing?

Legal test: the respondent applied to dismiss the complaint

  • A respondent may apply to dismiss the complaint. It might be unfair to change the complaint after this happens.
    You must show that changing the complaint will help get to a “just and timely resolution” of the complaint.
  • The Tribunal will consider the effect on the process and the outcome.
    • How will it affect the time to solve the complaint?
    • How much would it cost the other side?
    • Would it affect a participant’s ability to present their side?
    • Would it affect a participant’s chance to have a say about something important? For example, something that could affect the outcome of the complaint.
  • In the application, explain:
    • How is the change important?
    • Why didn’t you change the complaint earlier?
    • How will the change affect the respondent’s application to dismiss the complaint?

Legal test: change to complaint is late

If the change to the complaint is late, you must show two things.

  1. There is a good reason to accept the new allegation. The legal term is that it must be in the “public interest”.
    Reasons include:
    • why you are adding the allegation late
    • why adding the new allegation would benefit the public
  2. The delay does not cause real harm to anyone. The legal term is no “substantial prejudice”.
    • The delay means the time after the 1-year time limit.
    • Real harm includes things like the respondent no longer has evidence they need to respond to the complaint.
    • Set out any harm. Explain how the Respondent can still defend against the allegation.
    • Or say, “I know of no harm to the Respondent.”
