A child charged with a delinquent act need not be a witness against, nor otherwise incriminate, himself or herself. Any extrajudicial statement, if constitutionally inadmissible in a criminal proceeding, shall not be used against the child. Evidence illegally seized or obtained shall not be used over objection to establish the charge against the child. A confession out of court is insufficient to support an adjudication of delinquency unless corroborated in whole or in part by other substantial evidence. (Added 2007, No. 185 (Adj. Sess.), § 2, eff. Jan. 1, 2009.)
