R ( H, A and O) v Southampton Youth Court  EWHC 2912 (Admin) - (see, in particular, paras 33-35). Trial venue can be a difficult decision and the law is, to say the least, complex. The general aim of the system is to avoid Crown Court trial but, in some instances the law requires it in relation to very serious offending. The CPS website has a summary of the various provisions - see Youth Offenders.
Mrs Justice Andrews gave judgment in BH (A Child) v Llandudno Youth Court. I encourage the reader to look at the whole of the judgment. BH, aged 11 at the time of the alleged offence, was charged with a single count under the Sexual Offences Act 2003 s8(1) and (3) - causing or inciting a boy under age 13 to engage in a sexual act of a non-penetrative nature, namely to suck on his penis. See para. 4 of the judgment for further details. The incident is certainly not pleasant in nature but did such alleged conduct require the full panoply of a Crown Court trial? A District Judge considered that the matter should be handled by the Crown Court. On a judicial review of that decision, Mrs Justice Andrews, having considered various authorities, held that the District Judge was plainly wrong.
