(a) A properly addressed determination or decision is final for all purposes unless the party to whom it is mailed files an appeal no later than 14 calendar days after the mailing date.
(b) Each party to a complaint, adjudication, or appeal shall promptly notify, in writing, the Board, Board's designee, or the Agency with which the complaint or appeal was filed of any change of mailing address. Determinations and decisions shall be mailed to the new address.
  (1) A copy of the determination or decision must be mailed to a properly designated party representative in order for it to become final.
  (2) The Board or Agency is responsible for making an address change only if the Board or Agency is specifically directed by the party to mail subsequent correspondence to the new address.
  (3) If the Board, Board's designee, or Agency addresses a document incorrectly, but the party receives the document, the time frame for filing an appeal shall begin as of the actual date of receipt by the party, whether or not the party receives the document within the appeal time frame set forth in subsection (a) of this section. However, this does not apply if the party fails to provide a current address or provides an incorrect address.
(c) A determination or decision mailed to a party shall be presumed to have been delivered if the document was mailed as specified in subsection (b) of this section.
  (1) A determination or decision shall not be presumed to have been delivered:
    (A) if there is tangible evidence of nondelivery, such as being returned to the sender by the US Postal Service; or
    (B) if credible and persuasive evidence is submitted to establish nondelivery or delayed delivery to the proper address.
  (2) If a party provides the Board or Agency with an incorrect mailing address, a mailing to that address shall be considered a proper mailing, even if there is proof that the party never received the document.
(d) A complaint or an appeal shall be in writing. Complaints or appeals may be filed electronically only if filed in a form approved by the Agency in writing. The filing date for a complaint or an appeal shall be:
  (1) the postmark date or the postal meter date (where there is only one or the other);
  (2) the postmark date, if there is both a postmark date and a postal meter date;
  (3) the date the document was delivered to a common carrier, which is equivalent to the postmark date;
  (4) three business days before receipt by the Board or Agency, if the document was received in an envelope bearing no legible postmark, postal meter date, or date of delivery by a common carrier;
  (5) the date of the document itself, if the document date is fewer than three days earlier than the date of receipt and if the document was received in an envelope bearing no legible postmark, postal meter date, or date of delivery by a common carrier;
  (6) the date of the document itself, if the mailing envelope containing the complaint or appeal is lost after delivery to the Board or Agency. If the document is undated, the filing date shall be deemed to be three business days before receipt by the Board or Agency; or
  (7) the date of receipt by the Board or Agency, if the document was filed by fax.
(e) Credible and persuasive testimony under oath, subject to cross-examination, may establish a filing date that is earlier than the dates established under subsection (d) of this section. A party shall be allowed to establish a filing date earlier than a postal meter date or the date of the document itself only upon a showing of extremely credible and persuasive evidence. Likewise, when a party alleges that a complaint or appeal has been filed that the Board or Agency has never received, the party must present credible and persuasive evidence to support the allegation.
(f) A decision or determination shall not be deemed final if a party shows that a representative of the Board, the Board's designee, or Agency has given misleading information on appeal rights to the party. The party shall specifically establish:
  (1) how the party was misled; or
  (2) what misleading information the party was given, and, if possible, by whom the party was misled.
(g) There is no good cause exception to the timeliness rules.
