Representation before the State Tax Commissioner is governed by the applicable statutes and decisions of the Nebraska Supreme Court. These rules shall not, however, prohibit anyone from representing themselves or transacting his or her own affairs.
All notices required under these practice and procedure regulations, other than notices scheduling informal conferences, shall be mailed certified mail, return receipt requested, to the last known address of the party, his or her representative, or served personally.
A petition, other than a petition regarding a procurement action, is considered filed with the State Tax Commissioner on the date that it is received by the State Tax Commissioner, or if delivered by United States mail after the due date, the petition is considered filed with the State Tax Commissioner on the date of the postmark of the United States Post Office stamped on the envelope. Postmarks made by other than the United States Post Office will not be accepted as conclusive evidence of the filing date of any petition received after the due date.
Any petition regarding a procurement action must be filed within seventy-two (72) hours of the release of the Request for Proposal or the Invitation to Bid, or twenty-four hours prior to the submission date and time, whichever is earlier, or within seventy-two (72) hours of receipt of a notice of a rejection of a bid or proposal or notice of a contract award. For a petition on a procurement action, the petition must be physically received by the State Tax Commissioner within the appropriate time period.
