Could unregistered access agreements be enforced under section 150(2) of the CMA 1998?

No, section 150(2) of the CMA 1998 provides that no written access agreement shall be enforceable unless it has been registered with the Commission. Parties to Access Agreements have an obligation to submit their written Access Agreements to the MCMC for registration. In order to enforce the Access Agreement or to seek resolution as provided under the CMA, the pre-requisite is for the Access Agreement to be registered with the MCMC.
