PENAL CODE SECTION 1214.1
  
1214.1.  (a) In addition to any other penalty in infraction,
misdemeanor, or felony cases, the court may impose a civil assessment
of up to two hundred fifty dollars ($250) against any defendant who
fails, after notice and without good cause, to appear in court for
any proceeding authorized by law or who fails to pay all or any
portion of a fine ordered by the court.
   (b) The assessment shall not become effective until at least 10
calendar days after the court mails a warning notice to the defendant
by first-class mail to the address shown on the notice to appear or
to the defendant's last known address.  If the defendant appears
within the time specified in the notice and shows good cause for the
failure to appear or for the failure to pay a fine, the court shall
vacate the assessment.
   (c) If a civil assessment is imposed under this section, no bench
warrant or warrant of arrest shall be issued with respect to the
failure to appear at the proceeding for which the assessment is
imposed or the failure to pay the fine.  An outstanding, unserved
bench warrant or warrant of arrest for a failure to appear or for a
failure to pay a fine shall be recalled prior to the subsequent
imposition of a civil assessment.
   (d) The assessment imposed under subdivision (a) shall be subject
to the due process requirements governing defense and collection of
civil money judgments generally.
