Petition deadline is the date the petition must be received by the Court.

Petitions may be electronically filed with the Court. However, original petitions must be received by the petition deadline for the matter to be scheduled on the appropriate trial calendar. If the electronically filed petition is received before the petition deadline, but the original petition is received after the petition deadline, the petition will be docketed on the date the electronic version is received but the scheduling order issued will set the matter on the next trial docket. Service of the petition and scheduling order by the clerks is not made until after the original petition is received.  The original petition must be filed with the Court within 3 days after the electronic petition is received. ARM 24.5.303(6).
