Our conclusion that the Judge should be taken to have proceeded under s.120 fits in with the position established by s.124. That provides in subs.(1) that prima facie a conviction is not to be recorded against a child offender. The section goes on to deal with particular situations. Referring to s.120, for orders made under subs.(1)(a) or (b), no conviction may be recorded: s.124(2). For orders under s.120(1)(c) to (f) a conviction may be recorded: s.124(3). Referring then to s.121, s.124(4) provides that "if a Court makes an order under s.121 ... and the order is not allowed under s.120 ... a conviction is taken to be recorded." In other words, if the Court imposes a penalty within the more stringent range provided for by s.121, a conviction is deemed to have been recorded. We say the more stringent penalty provided for by that section because the order made, in order to attract the automatic recording of a conviction, must not have been "allowed" under s.120. Now if an order were made for detention for, say, less than 10 years, in the case of a serious and life offence otherwise coming under s.121(3), and that were regarded as an order "under s.121", then s.124 would be left making no provision for the discretionary recording of a conviction. That circumstance would favour then the construction that these subject orders should be taken to have been made "under" s.120(1)(f), in the terms of s.124(3), so that the Court did indeed have a discretion to record a conviction. Otherwise one would be left with the unlikely result that a conviction would not automatically be recorded - s.124(4) not applying - and there would be no discretion to record a conviction specifically granted by the legislation, notwithstanding that such a discretion is granted for orders under s.120(1)(c) to (f), encompassing orders of comparable severity to the ones made here.
