Complex Litigation Cases

Maricopa County Local Rule 3.12

A "complex case" is a civil action that requires continuous judicial management to avoid placing unnecessary burdens on the court or the litigants and to expedite the case, keep costs reasonable, and promote an effective decision making process by the court, parties and counsel.

The Complex Litigation judges are:

  • Judge Danielle Viola
  • Judge Scott McCoy
  • Judge Dewain Fox

At the time of filing the initial complaint, a plaintiff may designate an action as a complex case by:

  • Filing a motion and separate certification of complex case civil case.
  • The motion is ruled upon by the Civil Presiding Judge within 30 days after the filing of the response to the designating party's motion.
  • The court may also decide on its own motion that a civil action is a complex case.
  • Parties shall not have the right to appeal the court's decision regarding the designation of an action as complex or non-complex.
  • The factors of a complex case can be found in Maricopa County Local Rule 3.12.
