A 27-year-old liquor store robber hoping to persuade the Court of Appeals to lighten his four-year prison term was warned that he could end up with a longer sentence.

Appeals Court president Sir James Astwood on Friday warned Dwayne Doars: "Looking at your case, the judge has been very generous with you. Something may be wrong with the sentence ...in your favour.'' Doars was convicted of stealing $96 from Devonshire Liquors on August 20, 1997.

He was prevented from robbing more cash by the store's Rottweiler, Jenny.

His previous convictions include forging cheques amounting to more than $2,000.

And Smith also stole a $2,000 Peugeot cycle shortly before the liquor store robbery.

Smith blamed cocaine, his addiction since the age of 15, for his crimes.

Puisne Judge Richard Ground activated a three-month suspended prison sentence, sentenced Doars to three years in prison for stealing from Devonshire Liquors, and nine months for stealing the cycle. The sentences were consecutive.

He was also sentenced to three two-year prison terms for the cheque forging and uttering offences, to run concurrently with the other sentences.

Doars is currently seeking legal aid, and asked to have his appeal adjourned while he was under review.

Sir James told Doars that although he was looking to have his sentence reduced, it was very possible that his sentence might be lengthened.

And he cautioned Doars, stating: "Looking at your case, the judge has been very generous with you.'' The appeal was adjourned until June 24.
