It is impossible to implement the administrative court's decision to return certain privatized companies to the state because the companies' actual situation in terms of factors such as employment have changed, state TV quoted Minister of International Cooperation Fayza Abul Naga as saying on Saturday.
In recent months, a series of Egyptian court decisions have challenged privatization deals.
In September, a court ordered that three industrial companies be returned to the state, as the deals that privatized them squandered public funds.
The court ruled that the sales of Tanta Flax and Oil Co., Misr Shebin al-Kom Spinning and Weaving and al-Nasr Company for Steam Boilers be annulled, and the companies and their assets be returned to state ownership.
In the same month another court ruled that the sale of more than 50 percent of Nile Cotton Ginning Co. in the late 1990s violated regulations, as its shares were substantially undervalued.
Lawyers and activists have pointed to numerous violations and the systematic squandering of public funds in such deals during the terms of former prime ministers Atif Sidqi and Atif Ebeid, as well as that of Ganzouri, who served in the same post in the 1990s.
