Docket Control Center Filing Requirements

All documents officially filed with the Corporation Commission must go through the Docket Control Center. Below are instructions to assist you when making paper filings.

They may also be submitted through mail or delivery to our Phoenix office. 

The Commission currently allows eFiling in most dockets. Additional eFiling information is available here.

  5. Each copy must be properly collated.
  6. No confidential or proprietary information may be included in the filing.
    1. It is the filing person’s responsibility to remove or redact any confidential or proprietary information that would not be appropriate for public view.

  8. Each filing made by a party or potential party to an existing Docket that is not a generic or rulemaking docket must be served on each party to the Docket, and the filing should include a Certificate of Service showing that this service is being or has been made.
    1. The parties for a Docket are shown on eDocket in the Service List tab for the Docket.
    2. If a party has consented to receive Service by Email (“Email Opt-in” is checked), you may provide the party service using the email address/es shown on the Service List.
    3. The Certificate of Service must list each party to whom service is being made, with the address used for the party, and the following (or substantially similar) language:

      By: _________________________________
      Signature [of person providing service]

      Name and Title of person providing service”
    4. While your filing will not be rejected if you fail to include a Certificate of Service, the ALJ may not be able to take any action in response to your filing without an assurance that service has been made on all parties. Thus, failure to include a Certificate of Service may cause delay.

If you have any questions concerning the filing of documents, please call Docket Control at 602-542-3477.
