When you are part of an inquiry, you can receive any evidence that you think will help you with your inquiry. You can use evidence that would not be allowed in a court of law if you think it will assist you. You can also ask people to promise to tell the truth, either by swearing an oath or making an affirmation, and one of your team members can ask them to do this. You can let people give evidence in different ways, such as in writing or electronically, and you can ask them to promise that what they say is true. You have the power to decide how you want to collect and use evidence to help you with your inquiry.
