§ 311.3. Petition; fact-finding hearings. 1. When two or more\nrespondents are charged in separate petitions with the same crime or\ncrimes the court shall conduct a single or consolidated fact-finding\nhearing. The court, however, upon motion of a respondent or the\npresentment agency, may, in its discretion and for good cause shown,\norder that any respondent be granted a fact-finding hearing separate\nfrom the other respondents. Such motion must be made within the period\nprescribed in section 332.2.\n 2. If such petitions, in addition to charging the same crime or crimes\nagainst the different respondents, charge other crimes not common to\nall, the court may nevertheless conduct a single fact-finding hearing\nfor the crime or crimes common to all.\n
