22. The arbitrators shall take, before the Minister or a justice of the peace, the following oath:
“I, A. B., do swear that I will well and truly examine into such claims as may be submitted to me for compensation for damages consequent upon the construction of public works, or for payment or allowance in respect of any contract; and that I will give a true judgment and just award thereon to the best of my knowledge and ability; and that, in giving such judgment, I will take into due consideration the benefits derived and to be derived by the claimants through the construction of such public work, as well as the damages suffered thereby. So help me God”.
