Chief Coroner Greg Forestell says due to a court challenge relating to the procedures followed at an inquest it will be impossible to start the inquest as scheduled.
Forestell apologizes to the Perry family for the impact this will have on them.
In a hearing last week, the judge ruled that lawyers from Horizon Health can seek standing at the inquest and that hearing is set to resume on Monday.
Perry died at the Regional hospital while a patient in 2012.
