The Court of Appeal is to be asked to increase the minimum jail term to be served by a millionaire, thought to be Britain's most prolific paedophile.
Some of Goad's victims were as young as eight-years-old
William Goad, 60, of Plymouth, was jailed for life last October for sexual offences against boys over 40 years.
The judge imposed a tariff of six years and two months, the minimum he must serve before any parole hearing.
Three appeal judges will be asked to rule this "unduly lenient" at a hearing in London on Wednesday.
Goad, of Ford Park Road, was sentenced to life in prison for each of 14 specimen counts of serious sexual assaults to run concurrently with a three-year sentence for each of two counts of indecent assault.
In court, he was described as a "voracious, calculating, predatory and violent homosexual paedophile".
Goad was said to groom his victims, some aged as young as eight, by offering them well-paid jobs in his shop and inviting them back to his home.
He treated the boys who came to his house to sweets, soft drinks and money and let them play pool or computer games.
Some of Goad's victims said he continued to abuse them three to four times a week for two to three years.
The court heard that two of Goad's victims, not among those to whom the charges referred, had committed suicide.
Passing sentence last year, Judge William Taylor credited Goad for pleading guilty, but added: "I make it as plain as I can that you will not be released until the authorities are perfectly satisfied that you no longer pose any threat to anyone.
"It may well mean in your case life will mean just that."
The Court of Appeal is being asked to declare the tariff set by the judge as "unduly lenient" by the Attorney General, Lord Goldsmith QC, after an appeal by the web-based support group for the victims of paedophilia, Phoenix Survivors.
The case will be heard by Lord Justice Kennedy, Mr Justice Simon and Mr Justice Bean.
It will be argued the sentence was unduly lenient in that the tariff failed to take account of the gravity of the offences and the aggravating features of the case and of the need to deter Goad and others from committing this kind of offence.
Phoenix Survivors founder Shy Keenan said: "There were dozens and dozens of victims.
"When we heard the tariff given, we were quiet appalled and felt that, in this instance, justice didn't reflect the harm done."
During the trial, David Batcup QC, defending, had said the fact that Goad had attempted suicide more than once indicated he recognised the gravity of his crimes.
