Author Jacques Pauw says his legal team will fight South African Revenue Services (Sars) in court.
Sars has opened a case against him for the contents of his controversial book, The President's Keeper's.
Sars argues that Pauw contravened tax laws by disclosing confidential taxpayer information.
The book accuses President Jacob Zuma of tax evasion among other shocking revelations.
According to Pauw's lawyers, the Tax Administration Act only applies to Sars officials and their non-disclosure of taxpayer information.
The author adds that public interest will also form the basis of his team's legal defence.
He argues that the material revealed in the book was done so in the interest of the South African public as it pertains to the President's affairs.
Wits Law Professor James Grant agrees the public interest is a relevant primary legal defence.
