A hearing to decide whether to resume the inquest into the death of Dr David Kelly will be held on 16 March.
Lord Hutton found that Dr Kelly had committed suicide
Oxfordshire Coroner Nicholas Gardiner said he would be holding the inquiry at the Old Assize Court in Oxford.
He must decide if an inquest into the death of the government scientist is still needed after the Hutton report.
Dr Kelly was found dead near his home in Oxfordshire last July after he was named as the possible source of a BBC story on the government's Iraq dossier.
Mr Gardiner said the convened coroner's court would hear representations from "properly interested persons".
"The matter will be dealt with in open court," he said.
The coroner has been considering statements from witnesses that were withheld from the Lord Hutton's inquiry, the findings of which were published in January.
The inquest was adjourned under Section 17a of the 1988 Coroner's Act while the inquiry was held.
Lord Hutton concluded Dr Kelly, 59, had killed himself by cutting his left wrist after taking co-proxamol painkillers.
