Section 71-0207. Pleas by mail

A  defendant charged with a violation of any provision of this chapter
  or rule, regulation or  order  promulgated  or  adopted  thereunder  may
  himself  plead guilty to the charge in open court. He may also submit to
  the magistrate having jurisdiction, in person, by duly authorized agent,
  or by registered mail, a statement (a) that  he  waives  arraignment  in
  open  court  and  the  aid  of counsel, (b) that he pleads guilty to the
  offense as charged, (c) that he elects and requests that the  charge  be
  disposed  of  and  the  fine  or  penalty fixed by the court, (d) of any
  explanation that he desires to make concerning the offense charged,  and
  (e)  that  he  makes all statements under penalty of perjury.  Thereupon
  the magistrate may proceed as though the defendant  had  been  convicted
  upon  a  plea  of  guilty  in  open  court,  provided  however, that any
  imposition of fine or penalty hereunder shall be deemed tentative  until
  such  fine  or  penalty shall have been paid and discharged in full.  If
  upon receipt of the aforesaid statement the magistrate  shall  deny  the
  same,  he shall thereupon notify the defendant of this fact, and that he
  is required to appear before the said magistrate at a  stated  time  and
  place  to  answer  the  charge  which  shall  thereafter  be disposed of
  pursuant to the applicable provisions of law.
