§ 311.3. Petition; fact-finding hearings. 1. When two or more
respondents are charged in separate petitions with the same crime or
crimes the court shall conduct a single or consolidated fact-finding
hearing. The court, however, upon motion of a respondent or the
presentment agency, may, in its discretion and for good cause shown,
order that any respondent be granted a fact-finding hearing separate
from the other respondents. Such motion must be made within the period
prescribed in section 332.2.

2. If such petitions, in addition to charging the same crime or crimes
against the different respondents, charge other crimes not common to
all, the court may nevertheless conduct a single fact-finding hearing
for the crime or crimes common to all.
