Farmer said he is seeking to reinstate the penalties handed down in the High Court.
All four avoided jail time when sentenced in 2012, when Justice Robert Dobson said the offending was much less serious than that involving other failed finance companies, such as Bridgecorp. They had been found guilty of making untrue statements in investment documents and advertisements in late 2007 and early 2008 and the Crown had initially sought jail terms.
The Appeal Court imposed custodial sentences after determining the original penalty didn't reflect the gravity of offending and didn't give sufficient weight to accountability, denunciation and general deterrence.
Jeffries was sentenced to eight months' home detention and 250 hours community work and Reeves was sentenced to nine months' home detention and 250 hours community work, having both initially been sentenced to 400 hours community work.
Graham and Bryant were each sentenced to six months' home detention and fines of $100,000 apiece. Graham had his sentence of community work reduced to 200 hours from 300 hours.
Colin Carruthers QC, appearing for the Crown, told the court this "is a serious case in the category of carelessness," and that the decision to omit the information in the Lombard prospectus wasn't open to the directors.
"That puts it into a significant category," he said.
The hearing is being heard by Chief Justice Sian Elias, and Justices Terence Arnold, William Young, Susan Glazebrook and Peter Blanchard. It is set down for one day and is proceeding.
The 4,400 Lombard Finance investors owed $127 million at the time of the receivership have been repaid 13 cents in the dollar, and are looking at an estimated recovery of between 15 per cent and 20 per cent.
