In any case where a youth is committed to any youth facility for an offense punishable by confinement in the penitentiary, and it is found by the state commissioner of public institutions that the youth facility is unable to benefit such youth, and that his presence is a detriment or menace to other youths in the institution, or to the general good of the facility, he may be returned to the court by which he was committed to the facility, and such court shall thereupon pass such sentence upon him as to confinement in the penitentiary as may be proper in the premises, or as it might have passed had it not committed him as a youthful offender. The Governor shall have power, when, in the judgment of the warden of the penitentiary and of the superintendent of the facility, it is advisable, to remit the penalty of any offender under the age of eighteen years confined in the penitentiary to a commitment to a youth facility.
