What action must a party take if they wish to initiate a hearing process?

To initiate a hearing process, a party must submit a formal request. This action is essential because it establishes the intent to proceed with a hearing and provides the relevant authority with the necessary information to begin the process. A formal request outlines the specific issues at hand and signals the need for a resolution, effectively prompting the legal system to engage with the matter.

The other options, while related to legal processes, do not specifically initiate a hearing. Notifying the attorney general may be necessary in certain cases, but it does not directly trigger a hearing. Waiting for a scheduled date implies that a hearing is already set, rather than initiating one. Filing a complaint might be part of the broader process leading to a hearing but does not explicitly serve as a request for a hearing, making it insufficient on its own for that purpose.
