Any difference under any provision of this Order, unless otherwise provided for, is to be referred to and settled by a single arbitrator to be agreed between the parties or, failing agreement, to be appointed on the application of either party (after giving notice in writing to the other) by the President of the Institution of Civil Engineers.

For the avoidance of doubt, any matter for which the consent or approval of the Welsh Ministers is required, or which is subject to the direction making powers of Trinity House, under any provision of this Order shall not be subject to arbitration.
