Disputes
Trading parties can raise a dispute if they believe another party in the market is operating incorrectly in relation to; incorrect data items, inaccuracy of settlement reports, non-adherence to the Market Arrangements Code (MAC) obligations and/or non-adherence to other areas of the code.
You can find out more about the different types of disputes below, along with a list of all active disputes.
Trading Disputes
Trading Disputes occur when two trading parties disagree on whether a data item has been accurately maintained, which has had an effect on Primary Charges. Under the Market Arrangements Code (MAC), parties have an obligation to ensure that data is maintained accurately. In the event of inaccuracy, raising a Trading Dispute effectively escalates the dispute to ensure rectification. Prior to raising a Trading Dispute, however, a trading party must make all reasonable steps to resolve the discrepancy with the parties involved.
For more information, please visit the Trading Disputes page.
Market Operator (MO) Disputes
The Market Operator (MO) Dispute resolution process aims to rectify any errors considered to be the cause of inaccurate results occurring within the Settlement Report. An error can be raised by the contracting wholesaler or retailer, but must not be due to errors in or omissions of any data items, as this would constitute a Trading Dispute.
For more information, please visit the MO Disputes page.
MAC and Non-Trading Disputes
MAC Dispute resolution is designed to resolve any issue, in which a trading party believes an organisation, either MOSL or another trading party, has failed to comply in accordance with their obligations, as stipulated in the market codes. A Non-Trading Dispute follows the same procedure as that contained within the MAC Dispute. The dispute will have the same process, but will differ in terms of the scope.
For more information, please visit the MAC and Non-Trading Disputes page.

FAQs
As the disputing party, you must ensure that you adhere to any SLAs which have been set for you. These are code-obligated SLAs which will help to ensure that all disputes are completed within a justified timeframe. Furthermore, it is important that, as the disputing party, you submit only accurate and correct data, when requested by MOSL.
MOSL, as market operator, retains an overall responsibility to provide independent case management capabilities for disputes in the market. Where MOSL is also a disputing party, we will ensure that we maintain separation when dealing with the dispute in our capacity as Case Manager. We will also ensure that no one making decisions regarding the resolution is involved in the overall management of the dispute. In all cases, MOSL will operate to a Code of Conduct to ensure appropriate behaviour and neutrality.
The 'expert' is appointed through mutual consent by participating disputing parties, to aid the resolution of a dispute. Experts can be nominated by any party or through a list of recommended 'subject matter experts' from the Academy of Experts.
The role of the expert is to act as an independent decision maker, who will deliver an overall judgement, oversee the creation of a remediation plan and disperse the total expenses and fees incurred through the MO Dispute process.
The expert will provide the MO disputing parties with a breakdown of fees and any reasonable expenses incurred. The disputing parties are required to share the fees and expenses equally, unless directed otherwise by the expert. The expert has the authority to direct one party to pay a larger sum (which includes, but is not limited to, fees and expenses).
