39 Prior to the repeal of s391(2) there does not appear to be a decision of this Court that expressly addressed these conflicting authorities on statutory provisions that bear some similarity to it. Nevertheless, it is unquestionable that in this jurisdiction it was accepted that s391(2), empowered the Court to backdate a sentence. In Doyle v R (1998) 105 A Crim R 199, Wright J at 206 said that s391(2) had permitted the court to backdate the commencement of a sentence. Crawford J (as he then was) said at 209 that it appeared to have been assumed that the power to backdate a sentence was given to the court by s391(2). Cox CJ, at 200, said that the power to backdate sentences was no doubt considered justified by the provisions of s391. His Honour also noted that in Rudman v R 16/1997, the Court of Criminal Appeal referred without any disapproval to the fact that the sentencing judge had backdated the sentence subject to appeal, and that in Williams v R, an unreported decision of the Court of Criminal Appeal on 28 August 1996, it was held that the sentencing judge had been in error in holding that he had no power to backdate the sentence. I have examined the file of the Court of Criminal Appeal in relation to Williams. The sentence that was the subject of that appeal was imposed by Wright J pursuant to the Criminal Code Amendment (Life Prisoners and Dangerous Criminals) Act 1994. That Act, s9(3), provided that when re-sentencing a prisoner serving a sentence of life imprisonment, "the court has the same powers and duties it would have had if the applicant had been convicted by that court of the crime ...". When sentencing Williams, Wright J said that the substituted sentence he was to impose "must commence to run from the date on which the life sentence was imposed". A ground of Williams' appeal against the substituted sentence was that Wright J had erred in law in so holding. The appeal was allowed and the substituted sentence was backdated to give Williams the benefit of pretrial time spent in custody. The notes of the Court's decision record that it found that s9(3) gave the sentencing judge the power to backdate the sentence of imprisonment pursuant to the Code. In Carr v R [1993] TASSC 20, an unreported decision A14/1993, the Court of Criminal Appeal substituted a backdated sentence of two months' imprisonment for a sentence of five months' imprisonment without discussing its power to do as it did. In Doyle, both Cox CJ and Crawford J said it was the common practice of this Court before the Code, s391(2), was repealed to backdate sentences. My review of the Court's sentencing database confirms the frequency of this practice.
