The Employment Security Law at 26 M.R.S.A. Sections1194(2), (3), (8), and (10) provides for the period within which an appeal may be filed by interested parties. When the period during which an appeal may be filed under the Employment Security Law ends on a Saturday, Sunday or holiday, the appeal period shall end on the next day which is not a Saturday, Sunday or holiday if the appeal is filed by delivery and is received in-hand by the agency. If the appeal is filed by mailing, however, the appeal period will not be extended, and the appeal must be postmarked within the statutory appeal period, unless the appeal period falls on a Sunday or a holiday, in which case the appeal period will be extended until the next day which is not a Sunday or holiday.
