Premier Daniel Andrews could soon be forced to hand over the web browsing history from his computer and every staffer in his office.

The Victorian Civil and Administrative Tribunal will rule on a case brought by Liberal MP Tim Smith, who is seeking a list of websites visited by all people employed by or seconded to the premier's office between January 1 and March 24 last year.

Mr Smith took the matter to VCAT after he was refused a request made last year under Freedom of Information laws to access the documents.

The Coalition said it wanted the internet browsing histories from the premier's office "to make sure that they're working".
