Section 4 amends Article 92(4) of the Industrial Relations (NI) Order 1992 to enable parties before the Industrial Court to engage legal representation with the exception of one jurisdiction which is related to the provision of voluntary arbitration in relation to industrial disputes. Legal advice states that failure to allow legal representation could lead to a challenge under Article 6 of the European Convention on Human Rights (Right to a fair trial). Voluntary arbitration, by its nature, would not benefit from legal representation.
