When a civil matter, commenced in or removed to the court, involves subject matter that
comprises all or a material part of the subject matter or operative facts of another action, whether
civil or criminal, then or previously pending in any court or administrative agency, counsel must
file a list and description of all such actions then known to counsel and a brief summary of the
relationship between the cases. If information concerning any such proceeding is obtained after
the filing of the original pleading in the latter case, counsel must notify the court and opposing
counsel in writing of the relationship between the cases. [Amended February 1, 2011]
