"We will therefore duly study the judgment, including a proper dissection and comprehension on its far-reaching implications on how Parliament conducts its constitutional function in future," spokesperson Moloto Mothapo said in a statement.
"In the interim, we accept without reservations the orders made in the judgment, particularly as they relate to Parliament, and therefore we will ensure they are fully realised."
The Constitutional Court earlier on Thursday ordered that the resolution passed by the National Assembly - absolving President Jacob Zuma from compliance with Public Protector Thuli Madonsela's remedial action - was invalid and should be set aside.
Reading out the judgment, Chief Justice Mogoeng Mogoeng said only a court of law could set aside the Public Protector's findings.
Madonsela found in her report Secure in Comfort , released in March 2014, that Zuma had unduly benefited from some of the upgrades. She recommended that he repay a reasonable portion of the R246m spent on the upgrades, and that the ministers involved in the project be reprimanded.
Mogoeng found that Madonsela's report and the one by Police Minister Nathi Nhleko absolving Zuma of liability were "mutually destructive".
"The judiciary should have been approached to ask the Public Protector's findings to be set aside. Only then could the president have disregarded the Public Protector's report and remedial action."
