(a) If a minor is found an unfit subject to be dealt with under the juvenile court law pursuant to Section 707, then the following shall apply:

1. (1) The jurisdiction of the juvenile court with respect to any previous adjudication resulting in the minor being made a ward of the juvenile court that did not result in the minor’s commitment to the Youth Authority shall not terminate, unless a hearing is held pursuant to Section 785 and the jurisdiction of the juvenile court over the minor is terminated.
2. (2) The jurisdiction of the juvenile court and the Youth Authority with respect to any previous adjudication resulting in the minor being made a ward of the juvenile court that resulted in the minor’s commitment to the Youth Authority shall not terminate.

   1. (A) Jeopardy has not attached and the minor was 16 years of age or older at the time he or she is alleged to have violated the criminal statute or ordinance.
   2. (B) Jeopardy has not attached and the minor is alleged to have violated a criminal statute for which he or she may be presumed or may be found to be not a fit and proper subject to be dealt with under the juvenile court law.

   1. (A) Jeopardy has attached.
   2. (B) The minor was under 16 years of age at the time he or she is alleged to have violated a criminal statute for which he or she may not be presumed or may not be found to be not a fit and proper subject to be dealt with under the juvenile court law.

5. (5) If, subsequent to a finding that a minor is an unfit subject to be dealt with under the juvenile court law, the minor is convicted of the violations which were the subject of the proceeding that resulted in a finding of unfitness, a new petition or petitions alleging the violation of any law or ordinance defining crime which would otherwise cause the minor to be a person described in Section 602 committed by the minor prior to or after the finding of unfitness need not be filed in the juvenile court if one of the following applies:

   1. (A) The minor was 16 years of age or older at the time he or she is alleged to have violated a criminal statute or ordinance.
   2. (B) The minor is alleged to have violated a criminal statute for which he or she may be presumed or may be found to be not a fit and proper subject to be dealt with under the juvenile court law.

6. (6) Subsequent to a finding that a minor is an unfit subject to be dealt with under the juvenile court law, which finding was based solely on either or both the minor’s previous delinquent history or a lack of success of previous attempts by the juvenile court to rehabilitate the minor, and the minor was not convicted of the offense, a new petition or petitions alleging the violation of any law or ordinance defining crime which would otherwise cause the minor to be a person described in Section 602 committed by the minor prior to or after the finding of unfitness need not be filed in the juvenile court if one of the following applies:

   1. (A) The minor was 16 years of age or older at the time he or she is alleged to have violated a criminal statute or ordinance.
   2. (B) The minor is alleged to have violated a criminal statute for which he or she may be presumed or may be found to be not a fit and proper subject to be dealt with under the juvenile court law.
7. (7) If, subsequent to a finding that a minor is an unfit subject to be dealt with under the juvenile court law, the minor is not convicted of the violations which were the subject of the proceeding that resulted in a finding of unfitness and the finding of unfitness was not based solely on either or both the minor’s previous delinquent history or a lack of success of previous attempts by the juvenile court to rehabilitate the minor, a new petition or petitions alleging the violation of any law or ordinance defining a crime which would otherwise cause the minor to be a person described in Section 602 committed by the minor prior to or after the finding of unfitness shall be first filed in the juvenile court. This paragraph does not preclude the prosecuting attorney from seeking to find the minor unfit in a subsequent petition.
