First Minster Carwyn Jones is to be called as a witness at the inquest into the death of sacked Welsh Labour minister Carl Sargeant.
The 49-year-old Alyn and Deeside AM was found dead at his home in Connah's Quay, Flintshire, in November 2017.
Four days earlier, he had been sacked from the Welsh Government amid allegations he "touched or groped" women.
A previous inquest heard the provisional cause of death was hanging.
On Friday, a pre-inquest hearing at Ruthin's Coroner's Court found Mr Sargeant had been taking anti-depressants at the time of his death.
The solicitor representing Mr Sargeant's family said Mr Jones must have been fully aware of his personal issues as they had been friends for 16 years.
But Mr Jones's solicitors disagreed with this claim. The hearing was told the first minister did not believe the former communities secretary was suffering from a mental health condition or any other vulnerability when he was sacked from the cabinet.
Mr Jones was not present but was legally represented at the hearing as he is being treated as an interested party.
Mr Sargeant's son Jack, who replaced his father as Alyn and Deeside AM after his death, attended the hearing.
The coroner for north Wales east and central John Gittins is hearing arguments as to whether the inquest should be broader in scope and examine the wider circumstances around Mr Sargeant's death.
