ACAS Concilliators at the Tribunal?

I've recently appeared before the Northern Ireland Industrial Tribunal and noticed that a Labour Relations Agency (the Ulster equivalent of ACAS) Concilliator was in attendance to help parties settle cases. The Concilliator was only there for the cases where there were Case management conferences and pre-hearing reviews. So the first question for GB Tribunal users (and any ACAS officers out there) is "Should ACAS send concilliators along to Tribunals to help settle claims at the case management/PHR stage?"
