The eDocket web site was designed to work with Windows Internet Explorer 10. IE 10 or higher will provide the best user experience on the website, however other browsers may also be used. Adobe Acrobat version X is the recommended version to print PDF documents and reports.
Most docket numbers have five elements. (Line-siting dockets have a sixth element at the end.) As an example, the Docket Number T-01234A-19-0021 would break down as follows:

T 01234 A 19 0021 XXXXX
1 2 3 4 5 6
  1. Docket Type. In the example, "T" means Telecommunications.
  2. Company Number. In the example, "01234" is the unique company number assigned to a specific company. In some dockets that involve multiple entities, such as in a Securities case with multiple Respondents, a company number will be created for the docket although it does not refer to a specific company or individual. In a generic or rulemaking docket, "00000" is used for the company number. In some miscellaneous case dockets, "99999" is used for the company number.
  3. This letter is a vestige of a prior system. The letter "A" is now used by default for new dockets.
  4. Year. The "19" designates the year the docket was opened. For example, this docket was opened in 2019.
  5. Matter. The "0021" is the unique identifying matter number assigned to this docket when the docket was opened. The "21" means that this was the 21st docket opened in 2019.
  6. Line-Siting case number. The extra 5-digit field is used for line-siting cases only ("L" docket type). It is assigned sequentially based on how many line-siting cases have been done in Arizona to date when the docket is opened.
The primary search options in eDocket are:
  • Docket Search
  • Document Search
  • Event Detail Search

Within each search type, you can filter results based on criteria entered. Search page results are restricted to 500 records.

All documents filed in any docket since approximately 2000 are available as PDFs on eDocket, with the exception of Transcripts. Additionally, many Commission Decisions issued before 2000 are available as PDFs on eDocket. The Commission continues to add older Decisions to eDocket as time permits.


Older documents not yet available on eDocket are saved on microfilm in the Docket Control office and can be viewed during regular operating hours. Documents on microfilm may be printed at a cost of 10 cents per page.

Yes. If you enter the 5-digit Decision Number in the search box at the top right of the screen, the result will be "Document Details," with three different tabs. The "Document" tab takes you to the PDF of the Decision (scroll down).
If you enter the year and matter numbers in the search box at the top right of the screen (e.g., "19-0021"), the result will be "Docket Details," with seven different tabs. The "Docket" tab takes you to general information about the docket, and the "Documents" tab takes you to a list of the documents filed in the docket to date (all of which are accessible as PDFs).
No, not at this time. However, the Commission intends to provide this enhancement in the future.

Yes. The Calendar link on the top right of the screen takes you to an interactive monthly Calendar that features past and upcoming events. Clicking on an event results in additional information for the specific docket/s involved, with the ability to link to individual dockets. The calendar can also be filtered by event type.


Additionally, the Search link on the top right of the screen takes you to a page with several search option tabs, including an Event Detail Search tab. Using this tab, you can search for hearings, other proceedings, and due dates for individual dockets within specified date parameters.


***A party to a case should not rely on the eDocket Calendar or Event Detail Search functions for the procedural schedule in the case. Each party is responsible for being aware of each proceeding date and procedural deadline established in a case and must review each Procedural Order issued in the case and attend (or review the archive for) each proceeding held in the case to ensure such awareness.***

Case-Related Document FAQs

An application is a filing in which a person specifically requests that the Commission grant the person a right, a certificate, a permit, another authority or approval, arbitration, or affirmative relief, other than in the context of a formal complaint.

A tariff is a document that outlines the terms and conditions – and frequently the prices charged – for services from a particular utility. Many utility tariffs are available on the Commission’s website by clicking on "Utilities" and then the utility type (Electric, Gas, etc.) The Commission also has a tariff library in its Utilities Division where people can research approved tariffs.

This is an abbreviation for Certificate of Convenience and Necessity. It is the permit that allows a utility to serve a specific geographic area. Before a company can provide a regulated utility service (water, electric, natural gas, sewer, or landline telephone), it must first obtain a CC&N that outlines the territory and terms under which the territory was granted.

An interconnection agreement establishes the specific terms and conditions under which one utility may connect its infrastructure to the infrastructure of another utility. These are most common in the telecommunications industry, when one company is interconnecting and using the "hardware and software" of another company.

Before a regulated utility can put all or part of its used and useful infrastructure up as collateral against a loan, or can enter into debt with a repayment term of 12 months or longer, it must submit a financing application and receive Commission approval. Financing applications are reviewed in detail to make sure ratepayers will somehow benefit from whatever changes or improvements come from the financing.

If a person has a problem with the way a utility is providing service or billing for service, the person can submit a public comment describing the problem to the Commission’s Consumer Services section. If the problem is specific to the person’s own service or billing from the utility, the Commission’s Consumer Services personnel will offer to assist in resolving the problem. Consumer Services will provide the informal complaint issue to the utility for response to the customer and Consumer Services. Consumer Services may also serve as an intermediary, and possibly even an arbitrator, in an attempt to resolve the problem without the need for a formal complaint and evidentiary hearing.


More information is available on the Consumer Services page: www.azcc.gov/utilities/consumer-services.

If a person is not satisfied after trying to resolve a problem directly with a utility or through Consumer Services, the person has the right to file a formal complaint under A.R.S. § 40-246. In a formal complaint, the person ("complainant") must include the name of the utility; a detailed written description of the problem, explaining what the complainant has done to address the problem so far; the specific statutes or Commission rules that the complainant believes the utility has violated; and the specific resolution the complainant is seeking. A complainant should not seek monetary damages, as the Commission legally cannot award such damages.


The Commission can also file a formal complaint against a company for failing to comply with Arizona statutes or Commission rules.

The process for a formal complaint is similar to a court case. The complainant and the utility will testify in front of an Administrative Law Judge ("ALJ") during an evidentiary hearing. The complainant bears the burden of proof as to the assertions made against the utility in the formal complaint. After the hearing, the ALJ will prepare recommendations for the Commissioners in the form of a Recommended Opinion and Order ("ROO"), which will be provided to the complainant and utility. The Commissioners will consider and vote on the ROO at a public Open Meeting.


More information is available on the Consumer Services page: www.azcc.gov/utilities/consumer-services.

An Order to Show Cause is filed by a Commission Division when it believes that a utility or another regulated entity has committed willful or serious violations of Arizona statutes or Commission rules. This is the most serious form of complaint that can be filed against a utility. An Order to Show Cause requires the utility to provide why it has acted or failed to act – in other words, to show cause as to why the utility should not be sanctioned for violating statutes or rules.

A motion to intervene is a request filed by an individual or entity that desires to become a party to a case. Becoming a party confers certain rights and responsibilities. For information about intervention, please go to: www.azcc.gov/hearing/how-to-intervene-in-a-case

Testimony is oral or written statements presented under oath to answer questions about the factual basis for a party’s position in a particular case. Most of the documents labeled as "testimony" in eDocket are pre-filed written testimony that parties were required to file before a hearing. Transcripts memorialize oral testimony and cross examination that takes place during a hearing.

"Exceptions" is the term used for a document filed within a specified period after a Recommended Order ("RO") or Recommended Opinion and Order ("ROO") has been filed by an Administrative Law Judge ("ALJ"), or a Proposed Order has been filed by a Commission Division, in which a party outlines the party’s disagreement with the recommendations made by the ALJ or the Commission Division. Only a party to a case may file exceptions. The deadline for exceptions to a ROO/RO/Proposed Order is included on a cover letter or memo to the ROO/RO/Proposed Order when it is filed.

A Procedural Order issued in a case, or an applicable Commission rule, may require a utility to publish notice of its application in a newspaper/s within the affected area or to provide specific notice using another method/s. An affidavit of public notice or an affidavit of publication is a notarized document setting forth the notice that has been provided, to whom it was provided, the date it was provided, and the manner in which it was provided. An affidavit of publication must be obtained from a newspaper publisher.

A motion is a formal request for the Administrative Law Judge ("ALJ") to take a specific action or rule on some aspect of a case. A party to a case should file a motion whenever the party desires for the ALJ to act or make a ruling. A party must ensure that the party’s motion conforms as closely as practicable to the Arizona Rules of Civil Procedure.

Public comments can include statements, letters, petitions, or other forms of communication about a case that are filed by non-parties. Public comments often include questions, concerns, or other statements filed by persons who could be affected by the outcome of a case.

Rate Case - Typical Flow

Rate case processes and timelines depend on many factors, most notably the Class of utility involved. Rate cases have many points at which the Utilities Division or outside parties, called intervenors, may influence how the case proceeds. Additionally, the procedural schedule for a case may be modified as the case progresses. The following process could be used for a typical utility rate case under A.A.C. R14-2-103.

A rate case generally is commenced when a utility files its Application. After this, the Utilities Division ("Staff") has 30 days to determine whether the Application meets the application submission requirements set by Commission rule (A.A.C. R14-2-103(B)) and can be deemed "sufficient." If the Application is not sufficient, Staff sends the utility a Letter of Deficiency explaining what must be done to make the Application sufficient. The utility is provided an opportunity to make the Application sufficient, generally by submitting additional information or documentation. Until an Application is deemed sufficient, as evidenced by a Letter of Sufficiency issued by Staff, the rate case will not progress.


A Class A or B utility of any type, and a Class C electric or gas utility, must include Direct Testimony in its Application filing to support the Application.

Once an Application is deemed sufficient, the Administrative Law Judge ("ALJ") will issue a Procedural Order ("P.O.") setting the schedule and procedural requirements for the case. The P.O. will require the utility to provide notice of the Application to its customers, providing the language to be used for the notice, the method/s of notice to be used, and the deadline for notice to be completed. The P.O. will also establish the deadline for intervention, dates for parties to file testimony, and (if a Class A, B, or C utility), the date/s for a hearing and any public comment session/s to be held.

After an Application is sufficient, the parties to the case begin what is known as "discovery," the process through which parties request information from each other, and submit information to each other, so that each party is able to talk to witnesses, obtain any records pertinent to the case, and prepare its testimony and other evidence to offer at hearing.


Parties sometimes disagree about what information may be obtained during discovery. If parties are unable to agree upon discovery, after having made a good faith effort to resolve the dispute through telephonic or in-person discussion, a party may file a motion for a procedural conference; may contact the Hearing Division’s administrative personnel ((602) 542-4250) to request a procedural conference; or may file a Motion to Compel or Motion for Protective Order, as applicable.


Subpoenas may be used during discovery and are obtained upon application to the Executive Director’s office. Additional information on subpoenas is available here: www.azcc.gov/administration/subpoena-forms

Except in rate cases for the smallest utilities (Class D and E), the utility and the Utilities Division ("Staff") are required to file written testimony to support their respective positions. Intervenors are required to file written testimony if they intend to present evidence at hearing, but otherwise may choose not to file testimony.

Usually, the testimony filed includes:


  • Utility Direct Testimony—filed with the Application
  • Staff (and any intervenor) direct testimony—responding to the application>
  • Utility Rebuttal Testimony—responding to Staff (and any Intervenor) Direct Testimony
  • Staff (and any Intervenor) Surrebuttal Testimony—responding to the Utility Rebuttal Testimony
  • Utility Rejoinder Testimony—responding to the Staff (and any Intervenor) Surrebuttal Testimony

The parties may engage in negotiations to determine whether the disputed issues in the case can be resolved by agreement. These settlement negotiations could result in a Settlement Agreement entered into by some or all of the parties to the case. If this occurs, the Settlement Agreement will be filed with the Commission prior to the scheduled hearing. If the parties believe a Settlement Agreement might be possible and desire more time for negotiations, the parties may file a motion requesting to have the hearing rescheduled.


Through discussions, the parties may reach agreement on many of the disputed issues in the case. The parties may choose not to enter into a Settlement Agreement, but instead to reflect these changed positions in their pre-filed Testimony or witness testimony at hearing.

The scheduling Procedural Order ("P.O.") for a Class A, B, or C rate case will schedule a pre-hearing conference to be held approximately one week before the first day of hearing. At the pre-hearing conference, any or all of the following, among other things intended to enhance the efficiency and orderliness of the hearing process or to ensure a more thorough evidentiary record, could occur:


  • The issues in the case may be clarified or simplified,
  • Oral argument on pending motions may be presented,
  • Rulings on pending motions may be made,
  • Objections to pre-filed testimony may be made and ruled upon,
  • Admissions of fact and of exhibits may occur (to avoid unnecessary proof at hearing),
  • Witness scheduling may be established,
  • Hearing procedures may be discussed, and
  • The parties may be notified of specific issues or subject areas that the Administrative Law Judge ("ALJ") desires to have addressed at hearing.

In a Class A, B, or C rate case, an Administrative Law Judge ("ALJ") presides over a hearing to examine the evidence in the case. The utility, any intervenors, and the Utilities Division ("Staff") are provided the opportunity to make opening statements, to present their own witnesses, to cross-examine other parties’ witnesses, to present documentary exhibits, and to object to other parties’ evidence. During the hearing, the ALJ and any Commissioners in attendance may question witnesses, and the ALJ may request that a party provide additional information or exhibits on specific issues. The ALJ may allow the parties to make closing arguments at the conclusion of the hearing or may require that the parties instead file post-hearing briefs.


Members of the public may attend hearings. The ALJ will allow public comments to be made on the first day of hearing, before the presentation of evidence begins.


If a Settlement Agreement has been filed, the hearing will focus on the terms of the Settlement Agreement and whether it is in the public interest.

If the Administrative Law Judge ("ALJ") requires the parties to file post-hearing briefs rather than to make oral arguments at the conclusion of the hearing, the ALJ will establish the deadline for those briefs to be filed. The ALJ may require that responsive briefs also be filed.


if a party has proposed a revenue requirement, rate base, rate of return, or rate design in the case, the alj will require the party to file final schedules with docket control and, additionally, to submit to the hearing division an electronic copy of each electronic file prepared in reaching its final position, with all calculations and formulas intact and with billing determinants proof of revenue included. The files need to be submitted to the Hearing Division on a USB flash drive unless another format is more appropriate.

After the hearing has concluded and any briefing has been completed, the Administrative Law Judge ("ALJ") prepares a recommendation to the Commissioners based on the law, the weight of the evidence received (including all admitted pre-filed testimony and other exhibits as well as all live testimony at hearing), any agreements that may have been reached, and the ALJ’s determination of what outcome will best serve the public interest. The ALJ’s recommendation is presented in a document called a Recommended Opinion and Order ("ROO"). The ROO may include requirements or reach conclusions that differ from the position of any party. A memo attached to the ROO states the estimated date on which the Commissioners will consider the matter at an Open Meeting and provides a deadline for exceptions to be filed (generally within 10 days after the ROO is filed).

Each party to the case may file exceptions to the Recommended Opinion and Order ("ROO"), to express the party’s disagreement with and any suggested changes to the ROO. Only parties may file exceptions.

Once a month, the Commissioners hold an Open Meeting to consider Recommended Opinions and Orders ("ROOs") that have been issued for different cases, among other things. Members of the public are generally given the opportunity to speak on a case prior to the vote. Any member of the public who wishes to speak on a case must indicate a desire to speak by filling out a speaker slip or signing up to provide comment using the Commission’s public computer terminal. Commissioners often ask the parties to answer questions about the case and to provide a response to the ROO. Amendments to the ROO may be offered by any Commissioner or by the Administrative Law Judge ("ALJ"). A Commissioner may also choose to pick up a party’s suggested changes as an amendment. Votes are taken on each amendment offered, and then a vote is taken on the final document (as amended, if applicable). The Commissioners may accept, amend, or reject the ROO and can also send the matter back to the Hearing Division for further examination, which may include additional proceedings.

If the Commission votes to approve a ROO (as amended, if applicable) at Open Meeting, the Commissioners will subsequently sign a Decision comprised of the ROO with any approved amendments. Once signed, the Decision is filed with Docket Control, where it is dated and assigned a unique Decision Number. The Commission sends a copy of the Decision to each party in the case.

Under A.R.S. § 40-253, a party to a case may file with the Commission, within 20 days after a Decision is issued, an Application for Rehearing of any or all of the issues resolved in the Decision. If the Commission does not grant an Application for Rehearing within 20 days after it is filed, it is deemed denied.

If a party’s Application for Rehearing is denied, the party may appeal a Commission Decision under A.R.S. § 40-254 or § 40-254.01, as applicable.
