A law expert thinks an injunction suppressing key details in the Tom Phillips case will be difficult to keep in place.

Media and authorities have been suppressed from discussing certain details related to the case since the Marokopa fugitive and his children were found last Monday.

Media lawyers have been advocating for the right to report and the Wellington High Court will hear the matter again next month.

Senior Law Lecturer Nikki Chamberlain told Heather du Plessis-Allan that it's very difficult to stop individuals discussing the details on social media.

She says unless you can make each individual subject to the injunction, you'd have to make the entire social media platform a party in the court order.
