The Attorney General is to review several cases involving child deaths, following the Court of Appeal's decision to overturn Angela Cannings' murder conviction.
Angela Cannings' husband Terry stood by her throughout
The 40-year-old from Salisbury, Wiltshire was originally sentenced to life imprisonment for the murder of her two baby sons, Jason and Matthew.
The prosecution partly based its case on the evidence of retired paediatrician, Professor Sir Roy Meadow, while Mrs Cannings had always insisted that the babies were victims of cot death.
On Thursday, Leader of the Commons, Peter Hain, confirmed a working group had been established by the Attorney General to consider all cases in which the doctor was involved in giving evidence.
Mr Hain described the case as "appalling" and said the government must make sure there were no more like it in the future.
Mrs Cannings had always insisted that the babies were victims of cot death.
Professor Peter Fleming, a paediatrician at Bristol's Children's Hospital said the outcome proved that courts were not the place to deal with cases of this type.
Wiltshire Police said the case against Mrs Cannings was based on a painstaking and thorough investigation, and with the help of acknowledged experts.
"This case was brought to court in consultation with the Crown Prosecution Service and was based on information that arose from the investigation, which was both painstaking and thorough," said a police spokesman.
"Considerable research was undertaken, together with the help of acknowledged experts in the fields of paediatrics and sudden and unexplained deaths of infants.
"In light of additional information, which was not available at the time of the trial, it was right that this matter was brought to the attention of the Appeal Court, so as to enable the due process of law to take its course. "
