28 U.S.C. § 2107 : US Code - Section 2107: Time for appeal to court of appeals

      (a) Except as otherwise provided in this section, no appeal shall
    bring any judgment, order or decree in an action, suit or
    proceeding of a civil nature before a court of appeals for review
    unless notice of appeal is filed, within thirty days after the
    entry of such judgment, order or decree.
      (b) In any such action, suit, or proceeding, the time as to all
    parties shall be 60 days from such entry if one of the parties is -
        (1) the United States;
        (2) a United States agency;
        (3) a United States officer or employee sued in an official
      capacity; or
        (4) a current or former United States officer or employee sued
      in an individual capacity for an act or omission occurring in
      connection with duties performed on behalf of the United States,
      including all instances in which the United States represents
      that officer or employee when the judgment, order, or decree is
      entered or files the appeal for that officer or employee.

      (c) The district court may, upon motion filed not later than 30
    days after the expiration of the time otherwise set for bringing
    appeal, extend the time for appeal upon a showing of excusable
    neglect or good cause. In addition, if the district court finds - 
        (1) that a party entitled to notice of the entry of a judgment
      or order did not receive such notice from the clerk or any party
      within 21 days of its entry, and
        (2) that no party would be prejudiced,

    the district court may, upon motion filed within 180 days after
    entry of the judgment or order or within 14 days after receipt of
    such notice, whichever is earlier, reopen the time for appeal for a
    period of 14 days from the date of entry of the order reopening the
    time for appeal.
      (d) This section shall not apply to bankruptcy matters or other
    proceedings under Title 11.
