The Change Process

The role of the Panel is to consider changes that have been raised, and recommend to the Authority whether these proposed changes should be implemented in the market codes.

MOSL, in its role, supports the change process by establishing working groups and managing consultations on the instruction of the Panel. We encourage parties that are considering raising a change to contact MOSL in advance so that we can support the Proposer develop the change.
