The Johannesburg High Court has set aside the International Relations Department's decision to grant Grace Mugabe diplomatic immunity.

Judge Bashier Vally found the decision to grant Mugabe diplomatic immunity was inconsistent with the Constitution.
EWN reporter Barry Bateman says the State argued it didn't confer diplomatic immunity, but merely recognised it.
