DMM Help: Guide to Classification of Documents

The table below provides information on how documents are classified.




(Note that examples do not represent an exhaustive list but merely are listed as useful guidance.)

Affidavits of Service

A notarized document that certifies service of Commission and Department issued documents. Typically signed by the Secretary, the document includes the document type, date of issuance and parties served.


Due to the file size of certain documents, it is necessary to break them into manageable pieces for posting to the website.  Going forward the category "Attachment" will no longer be used.  A petition will remain intact.  All pieces of a petition will be categorized as "Petition" and described accordingly, such as Attachment 1 to petition, Attachment 2 to petition, etc.


Brief on exception
Initial brief
Reply brief
Reply brief on exceptions
Post-hearing brief (& reply)
Letter in lieu of brief
Memorandum of law
(Cover letter included with filed document)


Comments & Reply comments from active parties
Comments on Staff White Paper
(Cover letter included with filed document)

NOTE:  Comments from the general public, including letters and e-mails, whether or not specifically solicited through a formal notice, are filed under the “Public Comments” tab on DMM.  The “comments” referred to here are typically longer, formal documents filed by parties under a “notice and comment” process that may be used instead of or in addition to evidentiary hearings.


Customer appeal documents
Appeal of shared meter decision
Appeal of informal hearing decision
Complaints by a telecom carrier against another telecom carrier
Complaints against a utility by a competitor

See NOTE under “Petition” about classification of initial documents in a formal case

Consumer Complaint Determination

The Commission’s determination on a consumer complaint.


General correspondence to or from Secretary or ALJ regarding procedural matters
Correspondence between Secretary or an ALJ, on the one hand, and active parties, on the other hand, regarding procedural or substantive matters, that do not fit into other categories such as “motion” or “ruling,” e.g., questions sent to parties regarding a filing or to be answered at an upcoming hearing. See NOTE 3 below.
Requests for party status
Notice of newspaper publication

NOTE 1:  Comments from the general public, including letters and e-mails, whether or not specifically solicited through a formal notice, are filed under the “Public Comments” tab on DMM and not as “correspondence” under the “Filed Documents” tab.
NOTE 2:  Cover letters accompanying filed documents are filed with the accompanying document and not as correspondence.  One exception to the general rule of filing cover letters with their accompanying document is that, in the case of a new filing that serves to begin a formal case, the initial document, generally a cover letter, is classified as a “petition” for the purpose of generating a case number.  See NOTE under “petition.”
NOTE 3:  Communications from an ALJ or the Secretary that establish procedural requirements such as scheduling milestones or documents to be filed are “Rulings” and filed as such, even if they take the form of informal correspondence.  ALJs and the Secretary will endeavor to identify such documents as rulings.
NOTE 4:  Motions or briefs or responses or replies to same submitted by active parties in the form of letters are classified as motions or briefs; authors of such letters should clearly identify their character in the subject line or first sentence of the letter.

Letter from Office Director under delegated authority, e.g., granting CPCNs, tariff approvals, or cable temporary operating authority

NOTE 1:  This category is reserved for outgoing letters issuing from the Commission or the Department of Public Service and is not used for incoming correspondence.

NOTE:  For purposes of generating a new case number, the initial document of a new matter is classified as a “petition,” regardless of how that document would otherwise be classified.  Often a cover letter serves this purpose.   E.g., the cover letter that accompanies tariff amendments and testimony in a rate case is classified as a “petition” to trigger the assignment of a case number.
