THE department of correctional services has reversed an earlier decision to allow convicted assassin Janusz Walus to marry gospel singer Berril Roy in Pretoria Maximum Security Prison. Walus is serving time for the murder of Communist Party leader Chris Hani in 1993, plotted with fellow prisoner and former Conservative Party MP Clive Derby-Lewis. Prison authorities say that the ban on the wedding is part of a general crackdown on prison luxuries. The authorities deny that the timing of the ban was directed at frustrating the Walus wedding. The last wedding in a prison is believed to have been in Johannesburg a year ago. Walus, who has applied for amnesty from the truth commission, has also launched a court case for the right to conjugal visits from partners.
