Any dispute arising on a claim for compensation under this Act, being a dispute for the determination of which provision is not made by or under any section of this Act other than this section, shall be determined, if the parties so agree, by arbitration or, in default of agreement, by the county court.
The county court shall have jurisdiction to deal with any dispute which by virtue of subsection (1) above is to be determined by such a court notwithstanding that, by reason of the amount of the claim or otherwise, the case would not, but for this provision, be within the jurisdiction of a county court.
