The pre-inquest review into the 11 deaths following the Shoreham air crash due to take place on Wednesday 24 January has been postponed.
West Sussex Senior Coroner Penelope Schofield said the Crown Prosecution Service had recently notified her that no decision would be reached before the date of the pre inquest review on whether or not the pilot of the aircraft will be charged with any criminal offences.
The pre inquest review has been rescheduled for Monday 26 March.
The Coroner has informed the families of the new date.
Ms Schofield described the decision to postpone as regrettable but with no decision from the CPS that little progress could be made.
She indicated she was still working towards holding the full inquest in the autumn if no criminal charges are brought. The inquest may have to be suspended if the CPS decides to bring criminal charges.
The 11 who died in the air crash were:
Maurice Rex Abrahams, 76 of Brighton
Dylan Archer, 42 of Brighton
Anthony David Brightwell, 53 of Hove
Matthew Grimstone, 23 of Brighton
Matthew Wesley Jones, 24 of Littlehampton
James Graham Mallinson, 72 of Newick
Daniele Gaetano Polito, 23 of Goring by Sea
Mark Alexander Reeves, 53 of Seaford
Jacob Henry Schilt, 23 of Brighton
Richard Jonathan Smith, 26 of Hove
Mark James Trussler, 54 of Worthing.
They were killed when a Hawker Hunter jet crashed during a display at the Shoreham Airshow on Saturday 22 August 2015.
