[12] Secondly, the appellants' proposition is a gloss upon, rather than an interpretation of, s 16(3) of the Bail Act. It may be accepted that lengthy detention without trial is not easily justified, but to say that it cannot be justified by the strength of the Crown case is a proposition not supported by any available reading of s 16(3).[5] Further, there may be several reasons for delay. In some cases, the delay may be due to the conduct of the accused. In some cases, it may be due to the conduct of the prosecution. In some cases, it may be due to the shortage of court resources to deal with a case involving many witnesses or a large mass of documentary evidence. In some cases, it may be due to a combination of all of the above. To the extent that the Crown is not intentionally, or by neglect, causing the delay, it becomes more difficult to accept that "delay of itself shows cause". Unacceptable risks of flight or witness tampering or further offending do not become acceptable because the case against the accused requires a lot of witnesses to be called and, therefore, a long time to get to trial.
