Section 72

When any person is, under the provisions of this Act, committed by an order or judgment of a court to a place of detention, the order or judgment shall not be invalidated by any subsequent proof that the person is not a child or young person; but in that case it shall be lawful for the court before which such proof is brought to order the production of the person before it for inquiry, and, if it thinks fit, to revoke the order of committal; and the order shall thereupon be cancelled.

When any young person has been committed to a place of detention in accordance with section 66, and it subsequently appears to any court that the person is of so unruly or depraved a character that it is undesirable that he should be further detained in a place of detention, it shall be lawful for the court to order the production of the person before it for inquiry, and, if it thinks fit, to make an order in respect of the young person under section 59(2)(a).
