Section 130.10. Summons; definition, function, form and content

1. A summons is a process issued by a local criminal court directing a
  defendant  designated  in  an information, a prosecutor's information, a
  felony complaint or a misdemeanor complaint filed with such court, or by
  a superior court directing a defendant designated in an indictment filed
  with such court, to appear before it at  a  designated  future  time  in
  connection  with  such  accusatory  instrument.  The  sole function of a
  summons is to achieve a  defendant's  court  appearance  in  a  criminal
  action  for the purpose of arraignment upon the accusatory instrument by
  which such action was commenced.
    2.  A summons must be subscribed by the issuing judge and  must  state
  or  contain  (a)  the name of the issuing court, and (b) the name of the
  defendant to whom it is addressed, and (c)  the  name  or  title  of  an
  offense  charged  in  the  underlying accusatory instrument, and (d) the
  date of issuance of the summons, and (e) the date and time  when  it  is
  returnable,  and  (f)  a  direction that the defendant appear before the
  issuing court at such time.
