The post-Apartheid Truth and Reconciliation Commission found that when Geldenhuys and General Ian Gleeson were informed that the SADF and Security Branch had assassinated Dr Fabian Ribeiro and his wife Florence Ribeiro on 1 December 1986 they failed to pass this information onto the Attorney-General or the police. The commission concluded that they both "acted in an obstructive way for which they are legally responsible". As part of the Commission's hearings it was alleged that Geldenhuys had also authorised the use of SADF special forces personnel to support the Security Branch's operations within South Africa; he denied having done so.[7]
In 2023, Geldenhuys was named as an accomplice to the torture and murder of anti-apartheid activist Abdullah Haron.[8]
