(a) Except as provided by AS 47.12.160(d) and (e) and AS 47.12.170, an adjudication under this chapter upon the status of a minor
(1) may not operate to impose any of the civil disabilities ordinarily imposed by conviction upon a criminal charge;
(2) does not operate to permit a minor afterward to be considered a criminal by the adjudication; and
(3) does not operate to permit the adjudication to be afterward considered a conviction, nor may a minor be charged with or convicted of a crime in a court except as provided in this chapter.
(b) The commitment and placement of a minor and evidence given in the court are not admissible as evidence against the minor in a subsequent case or proceedings in any other court, nor does the commitment and placement or evidence operate to disqualify a minor in a future civil service examination or appointment in the state.
