Donald Trump's ban from Facebook and Instagram has been upheld by Facebook's Oversight Board, APA reports citing BBC.
But it criticised the permanent nature of the ban as beyond the scope of Facebook's normal penalties.
It has ordered Facebook to review the decision and "justify a proportionate response" that is applied to everyone, including ordinary users.
The former president was banned from both sites in January following the Capitol Hill riots.
The Oversight Board said the initial decision to permanently suspend Mr Trump was "indeterminate and standardless", and that the correct response should be "consistent with the rules that are applied to other users of its platform".
The ruling means that Mr Trump's suspension remains in place for now.
The Board said Facebook must respond within six months.
Facebook's Oversight Board was due to announce its decision last month but delayed the ruling in order to review more than 9,000 public responses to cases, it said.
In the meantime, Mr Trump, who is also banned from Twitter, launched a new website on Tuesday to update supporters with his thoughts.
