The Prosecutor shall open the adjudicative hearing stating orally to the court the nature of the offense which he expects to prove, the proof he expects to produce to uphold the complaint and shall offer his evidence in support thereof. The legal representative of the minor shall then set forth in a concise manner the proofs for his evidence in support thereof. The Prosecutor and the minor charged with the offense may, in that order, offer rebutting evidence only against the evidence originally offered, unless the court, for good reason and in furtherance of justice, shall permit them to offer additional evidence upon the alleged offense.
