66. Unless otherwise agreed between the parties, any difference under any provision of this Order (other than a difference which falls to be determined by the tribunal) shall be referred to and settled by a single arbitrator to be agreed between the parties or, failing agreement, to be appointed by the London Court of International Arbitration on the application of either party after giving notice in writing to the other.
67.—(1) In proceedings for an offence under any provision of this Order it is a defence for the Harbour Authority to prove that it took all reasonable precautions and exercised all due diligence to avoid the commission of such an offence.
(2) If in any case the defence provided by paragraph (1) involves allegations that the commission of the offence was due to the act or default of another person, the Harbour Authority shall not, without leave of the court, be entitled to rely on that defence unless, within a period of seven clear days before the hearing, it has served on the prosecutor a notice in writing giving such information identifying or assisting in the identification of that other person as was then in its possession.
68. The Secretary of State may cause to be held such inquiries as she may consider necessary in connection with the exercise of any powers or duties conferred or imposed upon her and the giving of any consent or approval under this Order, and subsections (2) to (5) of section 250 of the Local Government Act 1972(1) shall apply to any such inquiry as if it were an inquiry held in pursuance of subsection (1) of that section and the Harbour Authority were a local authority.
