The appeal concerns a high court ruling in favour of lobby group Freedom Under Law (FUL) to set aside a decision to withdraw criminal and disciplinary charges against Mdluli.
An SCA court official confirmed the court would hear the appeal on April 1.
Mdluli, the NPA and the Specialised Commercial Crime Unit received the go-ahead to appeal to the SCA in the Pretoria High Court on December 2, 2013.
Deputy Judge President of the High Courts in Johannesburg and Pretoria Aubrey Ledwaba granted leave to appeal against Judge John Murphy’s ruling in September 2013 in favour of FUL.
Murphy had set aside the decisions to withdraw charges of money laundering and murder, and disciplinary proceedings, against Mdluli.
Ledwaba found there were compelling reasons to grant leave to appeal and there was a reasonable prospect that another court might come to a different conclusion.
FUL did not oppose the high court appeal application, indicating that the matter concerned issues of significant public importance which ought to be aired in the SCA.
