A mother wrongly jailed for the murder of two of her children is meeting the Attorney General on Monday.
Ms Cannings was given a life sentence in 2002
Angela Cannings' conviction was quashed in December 2003 when key medical evidence against her was discredited.
That evidence was from paediatrician Professor Sir Roy Meadow, called as an expert witness for the prosecution in many baby death cases.
The Home Office has refused to pay damages to Mrs Cannings, 41, of Saltash, Cornwall.
Mrs Cannings says she will be asking Lord Goldsmith for a public inquiry into how far courts should rely on the evidence from paediatricians in cases like hers.
Mrs Cannings, said: "Hopefully the meeting will be a positive one.
"We would like to see the whole system involving family court cases and paediatricians changed in the way they look at accused parents.
"The whole system has to change for the sake of the child and for the sake of the family and for the sake of devastation that it causes."
