An appeal may be withdrawn in writing by an appellant at any time prior to the rendering of a final decision. Subject to the existence of other appeals on the same application, in such event the appeal proceedings shall terminate as of the date the withdrawal is received. An appeal may be withdrawn under this section regardless of whether other nonfiling parties have relied upon the appeal filed by the appellant. [Ord. NS-2122, 2009; Ord. NS-2016, 2006]
