Egypt's State Commissioners Authority, a body that advises the government on legal issues, recommended on Monday the dissolution of the Freedom and Justice party (FJP) - the political wing of the Muslim Brotherhood.
The authority's report said that the prior decision, issued in June 2011 by the Political Parties Affair Committee, to accepted a request from the FJP's chairman Saad El-Katatni to form the party, is invalid.
Hence the implications of such a decision are also invalid, added the report.
The Authority's recommendations to the government are non-binding.
On 23 September the Cairo court for urgent matters ordered the banning of the Muslim Brotherhood’s activities.
The court also ordered the interim government to seize the group's funds and establish a panel to administer its frozen assets until any appeal had been heard.
On Monday, the Muslim Brotherhood appealed the court verdict ordering the seizing of the group’s funds.
The Brotherhood has existed outside of Egyptian law for decades and was only officially registered as an NGO in March 2013.
