The tribunal, which will offer a cheap way to challenge Charity Commission decisions, was due to open for business today. An OTS spokesman said there was a "minor delay due to administrative reasons". A new launch date has not been set.
The Government has insisted that all 12 members of the new Charity Tribunal will be appointed before it begins hearing cases.
So far only its president, charity lawyer Alison McKenna, is in place. Interviews for the 12 positions are expected to happen in April.
A spokeswoman for the Ministry of Justice said: "By the time the tribunal is hearing cases there will be a full complement." She added that the tribunal president could also hear cases alone.
