Johannesburg - Dentist Casper Greeff's urgent application to either be released on parole or have his case referred back to the correctional services minister for reconsideration was on Tuesday postponed indefinitely in court, The Citizen reported on Wednesday.
His application came after he was told he would only be considered for parole next January.
In court papers, Greeff said he served 13 years and four months in prison and was eligible for parole.
In February 2001, he was sentenced to life imprisonment for arranging the murder of his wife Estelle, who was strangled before her throat was slit.
Handyman Elliot Masango and Christopher Njeje, who admitted to murdering her, were also sentenced to life imprisonment. The report did not provide information on them.
Greeff, once a prominent Kempton Park dentist, began studying biblical archaeology at the University of South Africa in 2003 and was conferred a doctorate in 2010.
He received a master's in ancient near-Eastern studies cum laude in 2013, with a dissertation on dentistry and dental disease in ancient Egypt.
He has also written articles about his field for internationally accredited journals.
