When a judge is deciding what happens with a child's case at this stage, they can look at all evidence that both sides bring forward, as long as it's relevant. But the judge doesn't have to treat every piece of evidence equally. If something seems unreliable, repeats what's already been shown, or is just being used to slow things down, the judge can limit how much weight it gets or even keep it out.
This part of the process works a bit differently than a full trial. At this hearing, the judge or review body is allowed to consider evidence that normally wouldn't be allowed later on, at the actual adjudication hearing where the main facts of the case get decided. This gives the court more flexibility to gather information early on, even if that information would face stricter rules later in the case.
For families involved in these proceedings, this means the hearing may include a wider range of information than what shows up in a formal trial. It also means the judge has real discretion here. They're trusted to sort through what's useful and what's not, rather than being locked into strict evidence rules from the start.
