The board's record of the date and time of receipt of the petition is evidence of the date of filing. Filings transmitted after 5:00 p.m., or on a Saturday, Sunday, or legal holiday, shall be considered filed the on next business day. If the last day for filing a document as required by these rules falls on a day when the board is closed under WAC 461-08-320(3), then the time for such filing shall be extended until the end of the next business day upon which the board is open for business.
