Two victims and London Mayor Sadiq Khan were given permission last month to mountain a plea over the lawfulness of the decision to free the sequence sex attacker.
Three judges in London will hear the movement against the Parole Board over two days and Worboys, 60, is approaching to seem around videolink from prison.
He stays behind bars since a proxy bar on his release, primarily imposed by the High Court in January, was renewed by Sir Brian Leveson and Mr Justice Garnham during February’s hearing.
Worboys was jailed indefinitely in 2009, with a smallest term of eight years, for drugging and sexually assaulting womanlike passengers in his cab.
Many of his victims had been celebration in West End and Chelsea bars and Worboys would offer them champagne peaked with absolute sedatives to applaud a made-up lottery win.
He would try to infer this by showing them a conduit bag pressed with cash.
He would then pounce on his victims in the back of his car as they were left inanimate and incompetent to strengthen themselves.
Worboys, who now goes by the name John Radford, was convicted of 19 offences against 12 victims, but has been related to some-more than 100 complaints.
A Parole Board decision that he should be liberated on looseness after spending reduction than a decade behind bars was widely criticised by his victims and politicians.
Phillippa Kaufmann QC, for the victims, told the justice on the prior arise that it seemed something had left “very wrong”, and they were “concerned not only for themselves but for the wider open and women in particular”.
The victims were also concerned, she said, that the recover decision was “made wholly in secret”.
The Sun journal is also holding partial in the authorised movement after Sir Brian and Mr Justice Garnham gave permission to renter News Group Newspapers to plea the Parole Board’s refusal to tell its decision.
The Sun’s lawyers contend the refusal was “unlawful” and breaches the newspaper’s right to leisure of expression.
